Alpine day climbs typically require a variety of climbing with packs, so packing needs to be a thoughtful balance of necessity versus weight versus space. Here's my suggested list, with links to the gear I use.
Group Gear Provided
- Climbing protection
- Comprehensive first aid kit to stabilize bleeding and fractures
- Emergency communication - cell phone, satellite phone, or beacon device
- Emergency shelter
- Internal frame pack - I find the 30L range is ideal. Blue Ice Warthog 28L
- Appropriate footwear for the conditions or climb: approach shoes, light hiking, or crampon-compatible boots. Scarpa Gecko, Tech Ascent GTX, or Charmoz Pro GTX
- 1-2 Liters of water storage, in Nalgene bottles or in hydration bladders. More about my thoughts about water storage and treatment is here: LINK.
- Lunch - we tend to 3-4 breaks in a day, so a collection of snacks or a sandwich cut in two works well
- Sun screen and lip balm
- Small first aid kit with a couple of band-aids, aspirin, ibuprofen, your preferred blister repair. Also, an epi-pen if you have any critical allergies!
- Pocket knife
- Trekking poles - I'm a huge believer in trekking poles for approaching and returning hikes. Make sure they're three-piece poles, in case we need to carry them in our packs as we climb! Ski baskets for snowy conditions may be necessary.
- Climbing helmet. Black Diamond Half Dome
- Climbing harness - for alpine climbs, I really prefer a flat harness that packs small and weighs little. But if I know I'll have hanging belays or a lot of rappels, I'll pack the rock climbing harness instead. Blue Ice Choucas or Black Diamond Solution
- Belay device with a large "HMS" or "William" belay carabiner. Black Diamond ATC-XP Belay Device and RockLock Screwgate Carabiner
- Two smaller locking carabiners for anchoring. Black Diamond Positron Screwgate Carabiner
- One non-locking carabiner the same size as the smaller locking carabiner - so they can be matched. Black Diamond Hotwire Carabiner
- One 48" / 120cm double-shoulder-length sling. Black Diamond 18mm Nylon Runners
- CONDITION DEPENDENT - Ice axe for snow approaches. Black Diamond Raven Ice Axe
- CONDITION DEPENDENT - Crampons (may affect footwear decisions). Black Diamond Contact Crampons
Clothing - recommending clothing can be the hardest part in the Cascades. What I wear for a climb in May is dramatically different then for the same route in September. Here is a loose suggestion that may be changed depending on actual conditions.
- On head: Knit hat, ball cap, neck gaiter. Knit hat or neck gaiter may get dropped if the forecast is good. Outdoor Research Storm Beanie, Swift Cap, and Echo Ubertube
- On top: Short-sleeve shirt, active insulation, soft or hard shell, belay insulation. Insulation may be dropped if the forecast is good. Outdoor Research Growler S/S Shirt, Deviator Hoody, Ferrosi Hoody or Realm Jacket, and Cathode Hooded Jacket
- On hands: Light or lightly insulated gloves. Outdoor Research Stormtracker Gloves
- On bottom: Lightweight soft shell pants, rain pants. Rain pants may be dropped if the forecast is good. Outdoor Research Prusik Pants and Foray Pants
- On feet: socks. Darn Tough Hiker Micro Crew Cushion
