The Zpacks Radiant wool T-Shirt is made from the same durable, comfortable, and machine-washable Merino Wool fabric as our popular Mirage Sun Hoody. 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 everyday 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. 

Developed over 3,000 miles on the Continental Divide Trail & tested in the Alps, The Mirage Merino Sun Hoody is engineered to elevate your outdoor experience and be the pinnacle of natural ultralight sun protection and your go to base layer.

We’ve teamed up with Evolved Supply Co to create an expertly designed, ultra-comfortable, and lightweight sun hoody that provides superior sun protection, breathability, and advanced moisture management, ensuring you stay cool even during the most intense outdoor activities.

Thoughtful features include a quarter-zip to help regulate body temperature, a unique hood design to protect you from the sun while still allowing for air flow, and thumb holes that provide sun protection for your hands and prevent your sleeves from riding up.

Also available in a women's version here. Check out the rest of our Merino Collection.

Made from 100% natural, renewable Gostwyck Ultrafine Merino, this isn’t just a sleeping bag liner; it’s a statement piece in your sleep system. The sub-15.5 micron fiber is among the finest merino available anywhere, softer than 99.9% of other merinos, wrapping you in a truly frictionless, itch-free cocoon of comfort night after night on trail.

This luxurious Gostwyck merino doesn’t just feel indulgent; it performs at a level that belongs in a no-compromise kit. It moves moisture efficiently and dries dramatically faster than other merinos in humid, heavy air on trails like the Appalachian Trail or Te Araroa, so your sleep never feels damp, clammy, or second-rate.

The ultrafine fibers also deliver superior odor control, helping keep your sleeping bag noticeably fresher for far longer. Whether you’re in a tent, hut, refuge, hostel, or hotel, it adds an extra layer of protection and the quiet satisfaction of knowing you’re sleeping in the finest sleeping bag liner that money can buy.
