Serious warmth. Spacious comfort. Built for real nights outdoors.
When the temperature drops and comfort matters most, the Thermoshell Sleeping Bag delivers reliable warmth and room to move — without the cramped, minimalist feel of hiking bags. Designed for campers, hunters, and families who value a good night’s sleep as much as the day’s adventure, this bag brings genuine home-style comfort to the outdoors.
Using ThermoCore dual-layer synthetic insulation, the Thermoshell traps heat efficiently while maintaining its loft and performance even in damp conditions. A tough 210T ripstop polyester shell resists abrasion and moisture, while the soft brushed lining feels warm and welcoming after a long day outside.
Spacious by Design
Forget tight-fitting mummy bags. The Thermoshell’s semi-rectangular shape provides generous legroom and natural sleeping movement, perfect for side sleepers or anyone who prefers a relaxed fit. Its extra width makes it ideal for use on stretchers, airbeds, or camp mats — bringing genuine comfort to your campsite setup.
Adaptable Comfort in Any Season
Whether you’re camping in the high country or enjoying a crisp spring weekend away, the Thermoshell adapts to your conditions.
Full-length twin zips let you open it flat and use it like a duvet on warmer nights
A separate foot zip offers adjustable ventilation
The drawstring hood and draft tube help lock in warmth when the temperature drops

Sooo warm!
Toasty warm and super comfortable. Loved having a wider sleeping bag as I usually toss and turn in the night. No getting tangled up in this bad boy!

Warm without feeling bulky
Used this bag on a frosty Central Plateau trip and stayed warm right through the night. Plenty of room to move without cold spots. Impressed for the price.

Great for cold sleepers
I sleep cold and this bag genuinely surprised me. Paired with a decent mat it handled near-freezing temperatures easily.

Solid winter bag
Bought this for winter car camping. Zips feel solid and I like the foot vent when it warms up overnight.
