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.

Rep Zpacks on and off the trail with the Zpacks Trucker Hat. Great for blocking the sun, propping up rain hoods, or just looking stylish. Make all your friends jealous with this great addition to your pack or wardrobe.

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

Choosing the right layer for crisp spring mornings and chilly fall nights can be a challenge. Our Men's Ventum Shell is crafted to cut the breeze and trap warmth in your base layer or against your skin.

Ventum fabric strikes the right balance between cutting cold wind while still allowing enough breathability for sweat to escape when hiking on chilly mornings and evenings. Ventum fabric tests at 39.5 CFM under ASTM D-737.

It’s perfect for when a base layer alone is not enough, but insulation would make you overheat. Weighing under 2 ounces this is a must-have item for when you plan to hike in cool weather.

If you don't see your size, we also have some sizes available at a discount in our Bargain Bin while supplies last.

This is the lightest and most comfortable day to day t shirt.

A standard snap back adjustment will fit just about any head size.

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!
