Inferno 15F/-9C
Inferno 15F/-9C
800-Fill ProDown™ · Side Baffles · Alpine · Recycled Nylon · 2 Lengths

The Inferno 15F/-9C uses 800-fill ProDown™ for high warmth-to-weight ratio and cutting-edge materials resulting in an ultra-versatile alpine sleeping bag. The main body is designed for higher thermal retention, while the side baffles help reduce cold spots and retain loft — a bag engineered for shoulder-season alpine climbs, winter camping, and ski tours where temperatures drop well below freezing but the weight penalty of an expedition bag would slow you down.

800-Fill ProDown™
Premium 800-fill ProDown™ provides exceptional loft and warmth-to-weight ratio — stays lofty longer, traps more warm air per ounce than standard down.
High Warmth-to-Weight Ratio
ProDown™ + strategic baffle design delivers genuine alpine warmth without the weight penalty of expedition-class bags — for sub-freezing temps in a packable package.
Main Body Thermal Retention
Main body is designed with higher thermal retention — concentrates warmth where the body needs it most during long cold nights at altitude.
Side Baffles
Side baffles help reduce cold spots and retain loft along the body — keeps insulation from migrating, even as you shift positions through the night.
Alpine Versatility
Ultra-versatile alpine sleeping bag — works for shoulder-season alpine climbs, winter camping, and ski tours where temperatures drop below freezing.
Recycled Materials
Built with recycled content — helps reduce landfill waste and use of virgin materials without sacrificing warmth-to-weight performance.
15F/-9C Temperature Rating
EN/ISO tested 15F/-9C comfort rating — handles shoulder-season alpine conditions, late-fall and early-spring shoulder camping, and moderate winter use with appropriate base layers.
Draft Control
Draft collar and insulated hood seal in warmth at the head and neck — the two spots where most heat loss happens in a sleeping bag.
Regular & Long Lengths
Available in Regular and Long lengths to fit different body sizes and sleep styles — Long adds room for taller campers or those who want extra interior space.

What's Included
In Box
1 × Inferno 15F/-9C Sleeping Bag (with stuff sack + storage sack)

Use a sleeping bag liner to extend the bag's life and reduce wash frequency.

Spot clean small dirt and stains with a damp cloth and mild soap.

Machine wash in a front-loading washer on gentle cycle with a technical down wash (e.g., Nikwax Down Wash) — avoid top-loaders with agitators that can damage baffles.

Tumble dry low with 2–3 clean tennis balls to break up clumps and restore loft — takes 2–3 hours; air-dry thoroughly before storing.

Do NOT bleach, iron, or dry clean — solvents and heat damage the ProDown™ insulation and DWR finish.

Store loosely stuffed in the included storage sack (or a large cotton sack) — long-term compression in a tiny stuff sack damages loft.
