Complete Mt Baker summit packing list: essential gear + layers for climbing

backpack (50-75L): Osprey Aura AG 65 (Women’s) / Atmos AG 65 (Men’s)

I used my Osprey Aura AG 50 for our 2-day Baker climb and it was the perfect size for a one-nighter!

helmet: Black Diamond Half Dome Helmet (women’s) / (men’s)

A helmet is essential on any Baker route, not just for rockfall, but for icefall, crevasse hazard, and unexpected slips or impacts.

ice axe: Black Diamond Raven Ice Axe

Routes like Squak Glacier and Easton Glacier typically involve moderate slopes around 30–40°, with some short sections of steeper terrain (up to 45°) near the Roman Wall. You’ll be climbing for hours on snowy or icy surfaces, and having a reliable ice axe is absolutely critical for safety and efficiency on these sustained ascents.

harness: Black Diamond Couloir Harness

A lightweight, packable alpine harness that’s easy to put on over boots and layers is essential for tying/clipping into your rope on the glacier.

glacier rope: Black Diamond 8.9mm Dry Rope (40m)

We climbed as a 3-person rope team with a 40m dry-treated glacier rope, which gave us enough line for crevasse spacing and rescue systems.

mountaineering boots: La Sportiva Trango Tech Leather GTX Boots (women’s) / (men’s)

I wore these from the trailhead to summit and back— the perfect boots for navigating trails and glaciers in a single trip.

crampons: Black Diamond Contact Strap Crampons with ABS Plates

Expect to strap on crampons just after leaving camp, navigating a mix of gentle snowfields and steeper, icy sections on your way to the summit.

Lightweight strap-on models work well with most mountaineering boots, and ABS plates (the plastic pieces attached to the bottom) are absolutely non-negotiable— they prevent snow from balling up underfoot, which can cause dangerous slips on icy or angled terrain. Choose a sturdy 10- or 12-point crampon that can handle both the long approach and the technical summit push without weighing you down.

gaiters: Outdoor Research Expedition Crocodile Gaiters

Gaiters kept snow, ice, and sharp crampon spikes off my pants and socks, especially during steep climbing and step-kicking. These heavy gaiters are durable, secure, and essential for glacier travel on Baker.

trekking poles: Black Diamond Trail Trekking Poles

I used both poles for the approach; on the glacier, I switched to one pole in combination with my ice axe, which gave me extra support and stability without compromising self-arrest ability.

pro, assorted technical gear (as needed)

This is so highly specific to the route and conditions that I wouldn’t dream of writing a standard list of mountaineering pro for Baker, just keep this as a reminder to consider what protective gear is required for your adventure!

We personally used a picket on the Squak only once. Bring what your team needs to build anchors and perform a rescue— and make sure you’ve trained with it before the climb.

PLB/SOS: Garmin InReach Mini 2

A Personal Locator Beacon (PLB) is your lifeline in the outdoors and it is essential for EVERY SINGLE SUMMIT. I carry a Garmin InReach Mini 2, which allows me to send messages, get weather updates, track location, and place an SOS call in an emergency, even without phone service. It does require a subscription (starting at $12/month), but it’s worth every cent and has literally saved both of my parents’ lives in the backcountry!

GPS: CalTopo app on mobile

The absolute best GPS resource is the smartphone you already own, paired with a reliable, low-cost GPS mapping app that allows you to access detailed offline Topo maps and navigate via GPS satellites, even without mobile service.

My go-to is CalTopo, which costs just $20/year and is by far the most feature-rich, affordable, and accurate mapping tool out there.

First Aid Kit: Adventure Medical Kits Backpacker

I always pack a lightweight but thorough kit with painkillers, wound care, foot tape, and emergency meds— enough to support myself or a teammate during a long descent.

headlamp: Black Diamond Spot 400-R

Essential for camp, possibly also part of your climbing gear if you’re aiming for a sunrise summit. I highly recommend a rechargeable headlamp with at least 300 lumens for safe movement through exposed, technical terrain in the dark.

powerbanks: VRURC Portable Charger with Built-in Cables, 10000mAh

Staying charged on Baker was a priority— we relied on phones for GPS and route-finding and an inReach for updates and comms, so I carried a full powerbank in my pack for emergency recharging.

mountaineering tent: Black Diamond Eldorado (4-season)

We camped in a conical Omnipotent tent from the 70s that my dad likes to take out annually “for tradition’s sake”, but if you aren’t tied to tradition, you’ll probably be happy with a lightweight 4-season mountaineering tent like the Eldorado. This is a great choice for 2 people!

sleeping bag: Feathered Friends Murre EX 0 (comfort rated: -18°C) or Sea to Summit Spark 0

A zero-degree (Fahrenheit) bag was just warm enough for sleeping on the summit, paired with a good pad and down booties. It will feel like overkill on the approach, but you’ll be happy to have the warmth at elevation!

sleeping pad: Therm-a-Rest NeoAir XLite NXT Sleeping Pad

I used this inflatable pad directly on the glacier, and it was light, surprisingly warm, and compact. R-value is critical up here—don’t skimp on insulation between you and the snow.

camp pillow: Sea to Summit Aeros Premium

A luxury I’ll never hike without! Lightweight, compact, and so worth the space for better sleep on the glacier.

camp shoes: Mountain Hardwear Down Bootie (High Camp)

Light, packable, and crucial for keeping your feet warm at camp. Sleep with these on for the best result!

toiletries

Toothbrush, toothpaste, hairbrush, deodorant, medications, contact solution, wilderness wipes… whatever you need to stay clean and comfortable for a few days on the mountain.

camp stove (+ fuel): Jetboil Zip

A compact canister stove is ideal for making simple meals on a weight-sensitive trip— crazy fast, fuel-efficient, and effective even in heavy wind.

A conservative estimate for fuel is one 230g canister per 3 days per person, but a small group can easily share 1 canister for this overnighter.

mess kit + cutlery: Sea to Summit Frontier Ultralight Collapsible 4-Piece Dinnerware Set

At the very minimum, your mess kit should contain a spoon and cup; at most, it might extend to a bowl and fork. Plastic is more comfortable to hold onto than metal at below-freezing temps!

water filter: Katadyn BeFree 1.oL Water Filter

Useful on the trail approach where streams are available, but once on the glacier, we melted snow for water.

2x water bottles: Nalgene Wide Mouth

The wide-mouth design made it easy to add electrolytes or refill with boiling water, plus they resist freezing better than narrow bottles.

electrolytes: Liquid IV

With the high physical demands of this climb, I recommend mixing electrolytes into at least half of the water you’re drinking to stay hydrated and avoid crashing.

freeze-dried meals + snacks

I packed 2 full days of food, including freeze-dried dinners, protein-heavy snacks, and a few morale boosters like sour candy and jerky.

Favourite brands: Peak Refuel; Packit Gourmet; Backpacker’s Pantry; Real Turmat (European brand)

sports bra/shirt + hiking shorts for approach + underwear

I wore a sports bra and yoga shorts combo on the approach to the glacier, while temps were warm and the terrain mellow. Lightweight, breathable layers are ideal here— you’ll add glacier layers higher up.

sun shirt for approach: Arc’teryx Taema Hoody (women’s) / Cormac Hoody (men’s)

This long-sleeved sun shirt is a guide-favourite for blocking sun on the lower snowfields and glacier approach— wicks well, dries fast, and gives solid sun protection without bulk.

wool base layer: Smartwool Classic Thermal Base Layer Top (women’s) / (men’s)

A clean base layer for sleeping, merino wool for best warmth-to-weight ratio.

lightweight fleece mid-layer: Arc’teryx Rho LT Hoody (women’s) / (men’s)

This is the first layer I added over my sports bra when we started getting into more alpine conditions on the glacier. It fit well under the next layer.

synthetic insulation: Arc’teryx Atom Hoody (women’s) / (men’s)

This was the next layer I added on the glacier climb and I wore it all the way to the summit and back down. An excellent synthetic

heavyweight down jacket: Arc’teryx Thorium Hoody (women’s) / (men’s)

I didn’t bring this on my climb, but in hindsight, I’d absolutely add it for climbing in calm conditions— if the wind is low, wear the Thorium as an outer layer instead of a shell for added warmth during rest breaks or slow glacier travel. I find this more comfortable than a shell, but again, it only works if the wind is low!

shell jacket: Arc’teryx Beta SL Jacket (women’s) / (men’s)

My waterproof/windproof outer layer for exposed glacier travel and summit weather. Even if you’re wearing a down jacket as your outermost climbing layer, this is still essential for wind, snow, and storm protection, so carry it with you no matter what.

fleece mid-layer bottoms: Arc’teryx Kyanite Base Layer Bottoms (women’s) / (men’s)

Perfect as a second layer under soft shells and over merino base, I wouldn’t summit without them.

soft shell pants: Arc’teryx Gamma Pants (women’s) / (men’s)

These were my primary outer layer from Base Camp to summit— durable, flexible, and wind-resistant.

sun hat: Arc’teryx Gamma 5-Panel Cap

Perfect for the approach and I wore this under my helmet for most of the climb, too!

glacier glasses: Julbo Vermont

The combination of high elevation, full sun exposure, and reflection off the snow means your eyes are at serious risk of UV damage and snow blindness, even on cloudy or overcast days. Glacier glasses are specifically designed with high-coverage lenses and side shields to block light from all angles— unlike regular sunglasses, they offer full wrap-around protection. I wore mine from trailhead to summit and back, and they were absolutely essential for safe glacier travel.

2x neck gaiters: Buff Original + Buff Polar

I brought two: a lightweight Buff for sun and wind protection and a Polar Buff to protect my face from freezing wind. You never know which you’ll need and these are light!

beanie: Arc’teryx Mallow Toque

Very nice for the cold summit camp!

sun gloves: Outdoor Research ActiveIce Chroma Full Sun Gloves

These super-lightweight gloves are a total game-changer for snowfields, glacier travel, and high UV days— they protect your hands from rough snow and ice without adding warmth AND make it easier to hold an ice axe while you’re sweating. I wore these all the way up the glacier to the summit.

lightweight hiking gloves: Outdoor Research Trail Mix Gloves (women’s) / (men’s)

Essential for handling gear around the tent in the evening.

leather mountaineering gloves: Outdoor Research Extravert Gloves (women’s) / (men’s)

I was actually able to wear sun gloves all the way to the top of Mt Baker since we were climbing in the afternoon, but sunrise ascents may require a warmer climbing glove like these.

liner socks: Injinji Liner Crew

I always wear toe-sock liners under my boot socks to reduce friction and prevent blisters.

boot socks: Darn Tough Hiker Micro Crew Cushion Socks (women’s) / (men’s)

Perfect for the entire trip. These have been my go-to for years: durable, breathable, and just the right amount of cushion in my boots.
