Amazingly light but cuts the wind and holds the heat in with a layer underneath!

– Joe B., ★★★★★

The right layer can make all the difference. That's why the Ventum Wind Shell is purpose-built for those moments when a base layer alone isn’t enough, but an insulated jacket would be overkill.

A whisper-light layer that blocks the bite of the wind while staying highly breathable on the move, the Ventum Wind Shell starts at just under 2 ounces and disappears into your pack until you need it. 

Pairs well with an Octa Fleece Hoody to cut the wind and trap in warmth. Ounce for ounce the Ventum Wind Shell has the best warmth to weight ratio of anything we sell.

Whether you’re logging miles on a thru-hike or pushing big days in unpredictable weather, the Ventum Wind Shell keeps you focused on the journey, not your layers.

A few weeks earlier, I would have just lived with a cold head. But not now! For almost no weight and a tiny amount of space in my pack, I put up a strong defense against hypothermia. Another great product!

Couldn’t be happier with this down hood. Perfect for quilt users, doesn’t slide around or off your head at night like a beanie can on straight, slick hair. Much better than the hood on a sleeping bag, which can slide into your face when you turn, and of course can’t be detached for use as a separate warm hood. The ultra light weight is remarkable. It’s very warm and has a cozy fit and feel.

– Rachel M., ★★★★★

Zpacks Down Hoods are reversible, face whichever color you prefer outward.

I’m a cold sleeper and was looking for options to help keep my feet warm through out the night. In the past I’ve used wool socks which helped but didn’t quite keep the chill out. The first night I used the goose socks it was like heaven! They are so lightweight and add noticeable warmth! These will extend my hiking season well into the late fall, worth every penny!

– Kimberly N., ★★★★★
