---

-HEADWEAR-

• Beanie/Toque
  • Wool or synthetic. Must fit under a helmet. Easily replaced with hooded layers after the early season.
• Sun Hat
  • Ideally fits under a helmet. Ball caps with a button on top are NOT recommended. Visors or athletic hats are more comfortable, vent better, and are easier to clean and dry out.
• Buff / Neck Gaiter
  • UPF-rated is highly recommended. Lighter colors are better for warm conditions and darker for colder conditions.
• Glacier Glasses
  • These are mandatory. If using glacier glasses, look for lenses that are CAT4 rated and have side shields. Photochromic are more expensive, but usable in a wider range of light.
• Ski Goggles
  • For use in high winds and heavy snow and skiing downhill. These should be lightly tinted or photochromic.
• Helmet
  • A ski or snowboard helmet is necessary for the course if you are skiing or snowboarding. Preferably a helmet with MIPS. Ensure that your helmet fits as this is critical for safety and comfort.

–GLOVES–

• Liner Gloves
  • Thin, lightweight, wool or synthetic gloves. Size to fit snug but not too tight. Phone-compatible fingertips and palm texture are nice to have. These could be worn alone in temps greater than 25°F when it is dry. UPF rated are ideal.
• Hardshell Gloves
  • Waterproof and insulated. If the glove lacks insulation, size it to fit a liner glove inside. Mainly used in wet conditions, cold temps, or when not moving.

-BASELAYERS-

• Undergarments
  • Wool or synthetic. Long, compression-style undergarments can help reduce inner thigh chafing. Sports bras without shoulder buckles or clasps are more comfortable under a pack.
• Base Top
  • A lightweight, wool or synthetic sun hoody is ideal. UPF 30+ sun protection is best. UPF clothing works better than sunscreen.
• Base Layer Pants
  • Wool or synthetic. Typically thin. Bring 1 for the early or late season. Optional for mid-season (depending on weather).

-MIDLAYERS-

• Active Insulation Top
  • Lightweight “gridded fleece” or lightweight synthetic insulated jacket or pullover. Hood preferred. Active insulation weight – 40g/m2. Heavier insulation weight – 60-80g/m2. Alpha fleece works as well.
• Softshell Pants
  • Thin, weather-resistant, breathable, and stretchy. You will wear these a majority of the time.
• Softshell Jacket
  • A soft shell jacket is considered an “action layer.” Its materials are designed to stretch and breathe while also maintaining wind and water resistance. This allows the user to leave this jacket on for a wide range of temps and conditions throughout the day without the hassle of constantly changing layers. Windproof jackets are lightweight and packable but lack the breathability and stretchy nature of the soft shell. Windproof jackets are ideal for blocking wind and light precipitation during low-output activities.

-INSULATING LAYERS-

• Insulation Jacket
  • AKA the “puffy”. Down or synthetic. This piece is worn in cold conditions or when not moving. Hood preferred. If choosing down, water-resistant down treatment is preferred to help prevent matting and loss of insulating ability if the jacket gets wet.
• Down Parka
  • These jackets come in many shapes, sizes, and temperature ratings. If you tend to get cold easily, opt for a slightly warmer and more substantial parka. Otherwise, choose a down parka that is still fully baffled, includes a hood, and offers sufficient coverage over your waist. Must fit over all of your other layers. This parka is ideal for courses where evening and night time temps get very low, this will increase your comfort level considerably after a long day when you are spending time around camp in the evenings. It is optional depending on your comfort level in the cold and conditions for the week.

-HARDSHELLS-

• Hardshell Jacket (Available to rent)
  • Non-insulated jacket with a waterproof and breathable membrane. Three-layer construction is recommended. It must have a hood, ideally helmet-compatible. When sizing, make sure it can fit over other layers. Not insulated.
• Hard Shell Pants (Available to rent)
  • Non-insulated, waterproof, and breathable membrane. Full side zips are recommended. Ideally has at least 1/4 length zipper from the bottom of the pant cuff in order to get pants on and off while wearing mountain boots. When sizing make sure it is able to fit over a base layer and soft shell pants. Insulated ski pants are strongly discouraged due to lack of waterproofness and heavy insulation.
  • Note: If you are wearing ski/snowboard pants, then that layer should suffice; consider adding a base layer for additional warmth. However, if you do not have ski-specific pants, then you will want to stick to the base layer, soft shell layer and hard shell layer combination. Please feel free to reach out to the AAI Equipment shop with any further questions.

-FOOTWEAR-

• Socks
  • Wool or synthetic socks that are over the ankle height. If you are skiing then socks that are just below the knee, or go above the edge of your ski boot are recommended. Having two pairs on hand for the field days are also recommended in case a pair gets wet.
• Ski Boots (Available to Rent)
  • We strongly encourage the use of randonee (AKA AT or alpine touring) equipment. If you are an experienced telemark skier, modern telemark gear will also be accepted. Make sure your boots fit you snug enough for downhill performance, but are comfortable enough to keep your toes warm. The hinge should be flexible enough to allow for comfortable walking, even for long distances. They must be equipped with a deep rubber lugged sole.
    • If splitboarding, you will need touring-specific splitboard boots. We do not have these for rent.

---

• Skis/Splitboard (Available to Rent)
  • Skis with a backcountry flex (softer) are preferable to skis designed for hard-packed lift-serviced skiing. You may choose to bring either telemark skis or alpine touring skis. Telemark skis must be equipped with full metal edges. If you use a cable binding, bring a spare cable. Equip your skis with runaway straps. Alpine touring skis should use bindings that allow for forward and lateral release.
• Poles (Available to Rent)
  • Adjustable poles with a full-size snow basket are recommended. Ski/Probe poles are not a substitute for the avalanche probe.
• Skins (Available to Rent)
  • For the PNW, skins with more traction are recommended over skins with more glide.
• Avalanche Probe (Available to Rent)
  • A 230cm length is the minimum. If you are in the Cascades with an especially deep snowpack then a 320cm probe is recommended. Carbon fiber is lighter and suffers less deflection than aluminum models. Look for a model that has graduated depth markings for use during snow pit studies.
• Avalanche Transceiver (Available for Rent)
  • Your transceiver MUST be a modern, 3-antenna, single-frequency (457kHz) beacon. If your transceiver is older than 5 years, you should consider retiring it or returning it to the manufacturer to have it tested for function and frequency drift. Older 2-antenna transceivers are obsolete.
• Avalanche Shovel (Available to Rent)
  • We require metal (aluminum) shovels. Newer models are lighter, stronger, more packable, and more ergonomic than older ones. Avalanche shovels now have a UIAA rating, so keep that in mind when shopping. Additionally, we recommend a mid-sized blade that can fit in your pack. Smaller blades don’t move enough snow, and larger blades move too much snow where efficiency is lost. A shovel that has a hoe-mode and snow profile-friendly blades are also a bonus.
• Day Pack/Ski Pack
  • A 25L to 35L pack is an ideal size. Whatever you need to use for a full day out. For a ski-specific pack, your pack should fit well, move with you, and not be a major hindrance when downhill skiing. Choose a model with ice axe loops and straps to carry your skis easily. Some models feature additional avalanche features such as an “Avalung” or airbags.

• Crampons (Available to Rent)
  • Must be 12-point steep crampons with front points and compatible with your mountaineering boots. Strap-on or lightweight crampons designed for general mountaineering are not adequate for this course. Must fit your ski or snowboard boots.
• Belay Device
  • Bring an auto-blocking device that accepts 2 ropes.
• Helmet (Available to rent)
  • Must be UIAA-rated for climbing. Be aware that foam, break-away style helmets like the ones listed are susceptible to damage if being loaded in a checked bag.
• Harness (Available to rent)
  • Make sure the harness has a belay loop and gear loops. When sizing, it should fit over your clothes when you have multiple layers on. A harness with leg loop buckles can make getting in and out of your harness with your skis or splitboard much easier.
• Ice Axe (Available to rent) A straight or slightly curved shaft ice axe is recommended. An adze is required. Please contact the Equipment Shop if you have any questions. Ice axe leashes are discouraged and not recommended.
  
  • NOTE: For participants looking to continue on to higher-level courses such as AMTL 2 or Alpine Ice, a slightly curved ice axe in the 50-55cm range, such as the Petzl Sum’Tec is appropriate.
• Slings
  • One 48in (120cm) and one 24in (60cm) pre-sewn sling. Slings must be UIAA-rated for climbing.
• Carabiners
  • Must be UIAA-rated for climbing. Must have:
    • 4 large pear-shaped munter-style locking carabiners
    • 5 non-locking wire gate carabiners
• Prusiks
  • You will need 3 lengths of 6mm nylon cord: 13ft, 6ft, and 5ft. We have these as a kit at our Equipment Shop, and it is encouraged that you use these as they have been specifically chosen for this course. We recommend getting 3 different colors for easy identification.
• Internal Frame Pack (Available to rent)
  • A 65L to 75L pack is the recommended size range. Mountaineering specific packs, instead of backpacking packs, are a good way to shave weight. Should also have the ability to carry weight well.

• Tent (Available to rent)
  • Four-season tent. If your tent does not have wind lines, an additional 6-10ft of 3mm accessory cord is needed for rigging your rainfly in a mountain environment. It’s possible to share if you would like.
• Sleeping Bag (Available to rent)
  • Synthetic or down. If you bring a synthetic bag, bring one on the lower end of the temp range since synthetic bags tend not to be as warm as down. If you sleep cold, bring a warmer bag than required. If choosing down, water-resistant down treatment is preferred to help prevent loss of insulating properties if the bag gets wet.
• Compression Stuff Sack 
  • For your sleeping bag. A waterproof compression sack is recommended.
• Sleeping Pads (Available to rent)
  • Bring 2. One inflatable and 1 closed-cell foam. The foam pad helps insulate from the snow and serves as a backup to the inflatable pad.

-Camp Kitchen-

Link to all camp kitchen items below.

• Stove (Available to rent)
• Fuel
  • Can be bought the morning of your course. More will be needed due to needing to melt snow for water.
• Pot
  • Bring 1 bigger pot for cooking and melting snow, 1.5L to 2L
• Utensils
  • Don’t forget the official “most forgotten item” – The spoon or spork. Long-handled spoons make stirring hot liquids safer and metal ones tend not to break as easily in cold temps.
• Bowl
  • Early Season: Bring a plastic bowl or mug, preferably with insulation
  • Mid/Late Season: Bring a plastic bowl, insulation not necessary
    • NOTE: If you have a Jetboil or MSR Reactor type stove and plan on eating out of your integrated pot, then you don’t need to bring a bowl. The same applies if you plan on using commercially packaged dehydrated or freeze-dried meals.
• Lighters
  • Bring 2.
• Hydration
  • A 3L capacity is recommended, though some people need more. A common approach is to bring a 2-3L bladder and a 1L hard-sided bottle. The bottle is important as a backup to the bladder if it gets punctured. A hard-sided bottle may also double as a mug for hot water, though not every bottle is designed to hold boiling water. Bring more water carrying capacity, usually in the form of bladders (4 to 8L) to reduce the number of times you need to melt snow.
    • For Camelbak-style hydration bladders, bring a drinking tube insulator, as the tube can freeze up. Drinking tubes must also have a lock on the bite valve. If you choose to use this system, be aware that it requires constant vigilance to avoid freezing. Be prepared to have to pull your bladder out of your pack to drink, as hoses freezing is a persistent issue on programs.
• Water Bottle Parkas
  • These are insulating jackets for your water bottles, one for each bottle. Should cover the entire bottle, including the lid. Having an insulated water bottle takes the place of this.
• Water Purification
  • Water purification of some form is required. A water filter is highly recommended, as water purification tabs don’t function in cold water. Steripens are an acceptable alternative to purification tablets. Integrated filters like the BeFree and Quickdraw are preferred.
    • NOTE: Pumps can be damaged by silt in the glacial water and can easily freeze at night and crack.
• Food
  • You are responsible for your own food for the duration of the course. Please consult our meal planning page. You should arrive with enough food for the course. There may be time halfway through to restock some items.

• Toothbrush & Toothpaste
  • Travel size recommended.
• Hand Sanitizer
  • Required. Used after going to the bathroom and before eating. Wet wipes can be used for the “mountain shower”.
• Alarm Clock
  • You will be responsible for waking up at certain times throughout the program. While your guide can sometimes be your alarm, there are often situations where tents are far apart. Be sure if you use your phone as an alarm, you have enough backup battery to accommodate for this. If you plan to use a watch, be sure your alarm is loud enough to work for you.
• Toilet Paper
  • The provided solid waste bags have a small amount of toilet paper with them, but most people do not find this to be adequate. Estimate how much you’ll need for a program of this length and place that in a plastic zip-lock bag. An extra zip-lock bag can be helpful for pack-out of used paper. If you plan to use wet wipes, be wary of scented or exfoliating types as these can be an irritant for some people.
• Suncreen
  • At least an SPF of 30+, zinc-based is preferred. Small travel-size tubes are recommended so you can put them in a close-by pocket for easy access.
• Lip Balm
  • Make sure it is SPF-rated.
• Pee Cloth (Optional)
  • A reusable, antimicrobial pee cloth, used in place of toilet paper or wet wipes. Note that everything is pack-it-in/pack-it-out for Leave No Trace purposes. If toilet paper is used, it will have to be packed out. This also helps keep pack weight down.
• Urination Device (Optional)
  • Pee funnels such as the GoGirl or Freshette.
• Menstrual Cup (Optional)
  • As with toilet paper, everything in the backcountry must be packed out. Menstrual cups can help with waste needing to be packed out.
• Personal First Aid Kit
  • Band aids
  • Blister Treatment
  • Prescription Drugs
  • Ibuprofen, etc
  • If you wear contacts, make sure you have spares if you can’t see without them
• Repair Kit
  • Ski straps (voile style)
  • Duct tape (can be wrapped around a trekking pole or a water bottle. Gorilla Tape tends to be the best brand for the mountains).
  • Zip ties
  • Extra pole baskets
  • Multi-tool to repair bindings etc
  • Binding-specific screws
  • 2 trash bags that are big enough to line the inside of your pack with

These items are not required, although many are nice “luxury” items that can make your expedition more enjoyable. Remember that a few ounces here and there add up to extra pounds on your back and knees during your expedition.

• Navigation App
  • Optional smartphone app such as CalTopo, Gaia, OnX, etc. Please have maps of the area downloaded.
• Map and Compass
  • Map should be of Mt. Baker Area (Preferably Green Trails Maps #13SX). The compass must have a declination adjustment.
• Altimeter Watch
  • If you have one then bring it. It is a great tool to have in the backcountry, especially for navigation.
• Hand/Foot Warmers
  • Recommended for people that are susceptible to cold hands and toes. These should be small, disposable type products.
• Ski Crampons
  • Most useful for March courses. These come in a variety of widths; be sure yours are wide enough to fit the width of your skis.
• Small Foam Pad
  • Can be useful for sitting or kneeling during field instruction. Your pack can also serve this purpose.
• Ear Plugs
  • For defense against snoring and high winds.
• Comfortable Clothing and Footwear
  • Breathable footwear – like flip flops – as well as some comfortable cotton clothing can be nice to change into for when you are not in the backcountry.
• Car Charger
  • Consider bringing an extra battery pack as well; having a lot of people using car charger cables is difficult.
