It has four-way-stretch for a range of motion and a comfortable fit on different body shapes. The Radiant is perfect for a long walk in the woods, a trip to the gym, or as a casual every day tee. 

Natural wool fiber keeps you cool in the sun, warm when wet, and resists odor better than synthetics. Our material is soft against your skin with none of the typical itchiness that other wool fabrics suffer from. Our premium 96% Merino wool blend is also pre-shrunk and isn't fussy. Throw it in the washer and dryer with your regular laundry.

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.

Technical gear isn’t just for your pack. Every aspect of our Trail Cool Hiking Shorts was designed to meet the rigorous demands of thru-hikers, backpackers, and outdoor enthusiasts.

The articulated cut and 4-way stretch mean you’ll feel free to take on miles of rugged terrain with zero restrictions. Whether you wear them backpacking, running, or as ultralight swim shorts the Zpacks Trail Cool Shorts have you covered.
