Preparing to Climb Mt. Rainier in 2025: An Essential Guide Part 2 - Gear

Clothing

Base Layers: Lightweight moisture-wicking shirts (2 short-sleeve, and 1 long-sleeve) and bottoms (1) -  synthetic, no cotton.  Also, consider a hoodie - great for base warmth and sun protection.  I typically go with 2 pairs of synthetic socks.  Remember, you can 'wear' base layers dry while at camp, or in your sleeping bag.                          Insulation Layers: The next layer is comprised of a light softshell jacket, a vest, and a 'puffy' jacket.  These layers can be used independently, or together when needed. Add a down, or synthetic, heavily insulated hooded parka - this is your heaviest insulated layer.  For pants, go with softshell, or 'climbing' pants.                                                                                                Outer Shells: Waterproof (Gore-Tex, or other weather-proof material), and windproof jacket and pants. Pants should have full-length zippers for easy on/off access.                   Headwear: Warm wool or synthetic hat or beanie, a sun hat or baseball hat, and a buff for warmth and weather protection.              Handwear:  Light-weight gloves for climbing in calm/ warm conditions. Mid-weight ski-type gloves for more severe weather, and down or synthetic mittens for the most severe conditions.                                                     Footwear: Insulated single or double mountaineering boots, depending on weather, and gaiters.

Climbing Gear

Crampons: Ensure they're compatible with your boots.                Ice Axe and Trekking Poles: Make sure to have your ice axe fitted. Do not use the strap on the axe. Trekking poles are optional.  Harness and Carabiners: Harness should have adjustable leg loops. Bring at least 2 locking, and 4 non-locking carabiners.                                             Backpack: Make sure your pack is 65-80L, as you will be packing approx. 40 lbs. guided / 60lbs. non-guided.                                                                        Rope: If you are climbing on a guided expedition the ropes will be provided.  If not, consult a professional climbing store for appropriate rope and length.                                                      Snow Anchors: For crevasse rescue and pitching tents.       Glacier Glasses and Goggles: 100% UV protection and with side shields sunglasses, and ski goggles for extreme conditions.   Helmut and Headlamp: Helmut must meet industry safety standards.  Bring extra headlamp batteries.

Shelter

Tent: A tent that can withstand high winds. If you are on a guided climb the tents are most likely included.                               Sleeping Bag: Rated for temperatures below freezing (0-25 degreesF).                                                                            Sleeping Pad: Insulating pad for warmth.                                Stove, Fuel and Pot: For melting snow and cooking.

Navigation and Communication

Map and Compass: Detailed topographic map of the region.
GPS: With extra batteries. Also, many mountaineering watches have excellent navigation tools, including an altimeter.                                     Altimeter: To keep track of your elevation.                                Two-way Radios: For communication within the team.   Emergency Locator Beacon: For emergencies, including avalanche.

Food and Hydration

Water Bottles: Total capacity of at least 3 liters.                      High-calorie, Lightweight Food: Energy bars, nuts, snacks etc.  I like bringing slices of pizza - a good source of tasty calories – bring food you like.

Additional Safety

First Aid Kit: Tailored for mountaineering.                          Crevasse Rescue Kit: Including pulleys, prusiks, and slings.   Sunscreen: SPF 50+ and lip balm with sun protection.            Multi-tool or Knife: Useful for various tasks.                            Toilet Kit: Including toilet paper and waste disposal bags.
