ALPS Mountaineering Blaze 0° Sleeping Bag – 0°F TechLoft Silver Synthetic Mummy for Winter Camping

Warmth, comfort, and rugged reliability for cold nights

Prepare for cold nights in the backcountry with the ALPS Mountaineering Blaze 0° Sleeping Bag. This synthetic mummy bag is designed for winter camping and backpacking, offering warmth and durability without the bulk of heavier down systems. The balance of robust materials and thoughtful features aims to deliver a cozy night under the stars, even when the air turns crisp.

At the heart of the Blaze 0° is TechLoft Silver synthetic insulation. Its multi-denier staple-length fibers and siliconized finish help preserve loft and thermal efficiency, so you feel supported through the night and wake up ready for the next adventure. The insulation works in concert with construction details that minimize heat loss while remaining manageable to pack and carry.

Key design elements for warmth and comfort

• Two-layer offset construction helps reduce cold spots by distributing insulation more evenly around the bag.
• Contoured mummy shape and a form-fitting hood seal in body heat, while a draft-blocking chest baffle and full-length zipper baffle curb chilly drafts.
• Durable polyester ripstop outer shell resists tears and rough terrain, paired with a soft polyester liner for comfort against the skin.
• Reliable hardware, including #8 separating zippers, ensures smooth operation in outdoor conditions.

Liveable warmth meets practical convenience. The Blaze 0° measures about 80 inches in length and 32 inches in width, offering generous space for most sleepers. With a weight around 5 pounds 5 ounces and a compact packed size, it aims to strike a balance between warmth and portability. The standard stuff sack aids straightforward packing for weekend trips or longer expeditions.

What makes it a versatile choice

• The soft liner and roomy cut provide a comforting feel after a long day on the trail.
• The durable shell and insulation configuration are suited for winter camping, mountaineering, and other cold-weather adventures.
