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.

Slept great this past weekend using it for the first time. I really like being able to control the firmness of the pillow by using the desired amount of extra clothing I’m carrying. And it’s a great waterproof stuff sack!

– Todd L., ★★★★★

A good night's rest isn't worth sacrificing. The Zpacks Padded Pillowcase adds luxury, and functionality to our Inflatable Pillow.

Soft Octa fleece is comfortable against your face, and a few layers of synthetic insulation adds a little bit of extra loft and cushion. 

Elastic straps on the back allow you to boost the height of your pillow with your sit pad, or any stuff sack or dry bag, and a shock cord strap secures the pillow to your sleeping pad to help prevent it from sliding.

This pillowcase is sized to perfectly fit our inflatable pillow, but it could also be stuffed with spare clothing like your Down Jacket. A zipper on the back of the pillowcase provides easy access to blow up your pillow, or to add or remove items.

Protect your investment with our Ultralight Sunglasses Case.

A microfiber cleaning cloth is included, and stores conveniently in the stretchy Lycra pocket. The cleaning cloth stays attached to a small loop inside the pocket so that it never gets lost.

Spare microfiber cleaning cloths are available here.
