The generous 3-D draft collar with elastic cord closure is simple to use, does not feel tight when used and can be opened easily when necessary.

Easy to handle flat cord lock 

Arm hole with closing snap

Stay warm while using your arm. Close the snap button, open the self-locking zipper and slip your arm through the gap. The hood stays in place and keeps you cozy.


Bartack reinforcements where necessary for enhanced durability.

Comfort hood

The large hood opening ensures a comfortable fit. When cinched tight on cold nights it seals accurately around mouth and nose. The inner lining doubles as the cinch cord guard preventing pressure on forehead and nose when the hood is closed. And the hood is large enough to hold a pillow.

Product description

The Winterlite -15° is the perfect choice for harsh weather conditions and demanding adventures in cold temperatures. The water-repellent, windproof shell fabric is made of a PFC free PU coating. It is lightweight and vapor permeable and protects against moisture or condensation. Ideal for sleeping under a tarp or in a snow shelter. The clever tuck-stitch technology ensures durability and optimal moisture control.

The Winterlite features an ergonomic fit for enhanced thermal performance as well as a proportional differential cut. The 3D foot box with 11 individually filled down chambers keeps feet warm. A puffy draft collar retains warmth within the sleeping bag.

Only RDS certified down is used in the Winterlite. All Winterlite sleeping bags can be paired with each other, with other EXPED models, as well as with most sleeping bags from other brands.
