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.

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!

Excellent! I have the worst circulation and have tried literally every glove and mitten on the market. My hands and fingertips freeze within a few minutes of being in the cold wether it's mild or below zero. These gloves keep my fingertips warm! I do not have to wear anything else.

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

– Joe B., ★★★★★

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.
