Specter 15F Sleeping Bag: 15F Down

What Our Gearhead® Experts Are Saying:

"I used this on a few alpine bivy nights where wind and frost were constant, and the shell handled moisture really well. The dual zippers are surprisingly useful when you're stuck in the bag but still need to cook or organize gear."

High alpine nights often arrive with cold wind, frost, and exposed camps. Mountain Hardwear built the Specter 15 Sleeping Bag to handle those demanding environments, giving us dependable warmth and weather resistance for big climbs, remote bivies, and cold backcountry camps.

An ultralight Pertex Quantum Pro Diamond Fuse shell provides durable weather resistance that sheds moisture while maintaining excellent compressibility. Inside, 800-fill RDS-certified goose down traps warmth efficiently without adding unnecessary weight to our pack. The performance mummy shape holds warmth close to the body while still leaving space for layering when temperatures drop further than expected.

A contoured footbox improves comfort and heat retention through the night, while the draft collar and down-filled face gasket seal in warmth around the hood opening. Dual side zippers allow ventilation or arm access without fully leaving the bag—an especially useful feature during alpine bivies when we need to handle gear or cook while staying insulated.
