Mountaineering Sleeping Bags

Gear up for cold-weather adventures with our high-performance mountaineering sleeping bags. Engineered for extreme alpine conditions, our selection features lightweight down and durable synthetic models designed to deliver maximum warmth without weighing you down.

Read Buying Guide: How to Choose (Materials, Temp Ratings & R-Value) ▼

1. Down vs. Synthetic Insulation

  • Down (700+ FP): Highest warmth-to-weight ratio and ultra-packable. Ideal for alpine expeditions. Hydrophobic down treatments add water resistance.
  • Synthetic Insulation: Retains heat even when damp. Excellent for wet environments or extended base camp stays.

2. Understanding ISO/EN Temperature Ratings

  • Comfort Rating: The lowest temperature for a comfortable night’s sleep. Use this as your primary benchmark.
  • Limit Rating: The lower threshold for a curled-up sleeper before feeling cold.
  • Extreme Rating: Survival limit only to prevent hypothermia; not intended for regular use.

3. The Importance of Mat R-Value

Ground heat loss is a major factor in alpine camping. Pair your bag with an insulated sleeping pad:

  • 3-Season Alpine: R-Value 3.0 – 4.5
  • 4-Season / Winter Expedition: R-Value 5.0+
