Snowbird™ SP550 Down Mummy Sleeping Bag 29.3°F / -1.5°C is engineered for outdoor enthusiasts seeking superior warmth-to-weight performance in cold conditions. Designed with premium duck down insulation and precision construction, it delivers reliable thermal retention while maintaining excellent portability for camping, hiking, and high-altitude expeditions.

Key Features
  • Professional Grade Insulation - Filled with 1000g of premium duck down (85% down content, 650 fill power), this sleeping bag offers exceptional lightweight warmth and softness. The C-shaped wrap design on the upper body maximizes down coverage, creating an enveloping thermal barrier ideal for high altitudes and cold environments.
  • High Performance Fabric - Crafted from soft, skin-friendly 20D nylon, the outer shell delivers outstanding breathability and water-repellent performance to withstand variable outdoor weather conditions, making it perfect for camping, hiking, holiday travel, and backcountry adventures.
  • Lightweight & Portable - Designed for easy transport and compact storage, this sleeping bag balances spacious comfort with exceptional packability. Its lightweight construction reduces carry burden and optimizes storage efficiency, ensuring hassle-free travel on every outdoor trip.
  • Warmth & Comfort Optimized - Featuring a thickened U-shaped hood with an adjustable drawcord, this mummy sleeping bag delivers a snug, wind-resistant fit around the head to block cold drafts. It ensures restful, fatigue-recovering sleep even in harsh winter conditions.
  • Refined Functional Design - The three-dimensional foot box and independent stripe channel construction ensure even down distribution and prevent down migration. A secure Velcro closure stops accidental zipper slippage during sleep. An innovative thermal pocket safely stores phones and small electronics—note: thermal pocket not included on 400G down sleeping bag.
