Zpacks Trail Cool Merino Wool T-Shirt
A super comfortable base layer for outdoor adventures.
Our ultralight 130 gsm material is very breathable, but still thick enough to provide miles of durability on or off trail.
The material is stretchy, allowing it to comfortably conform to your body's movements.
Raglan sleeves provide excellent range of motion while eliminating a top shoulder seam that could rub against your backpack straps.
Sizes are US Men's, however the athletic fit and stretchy material work well for women's figures as well.
Made with a 95% Merino Wool Blend, the shirt is soft and smooth against the skin with no itchiness or transparency.
- Wool stays warm when wet and also helps with temperature regulation in warm weather.
- Merino is unique in that it absorbs odors and reduces unpleasant smells.
- This garment is intentionally cut long. Expect wool to shrink a couple inches in length if washed and dried with regular laundry. Line dry to preserve the initial sizing if desired.
All Zpacks gear has a two year limited warranty against defects in materials or workmanship. Please see our return / warranty policy.

Zpacks Ventum Wind Shell
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 Ventum Wind 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.
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.
This windshell is unisex sizing. We do also have some women's sizes in our Bargain Bin while supplies last.
Fleece Hat
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!
– Jon B., ★★★★★
Stay warm and cozy when the temperature begins to drop, whether you’re on the trail or on your way to work. Ultralight and crafted with a double layer of micro-fleece around the ears, this hat was created to keep you warm but not weigh you down.

Goose Down Hood
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.
– Rachel M., ★★★★★
Get ready for sweet dreams on cold nights when bundled up with the Goose Hood. A perfect companion to your ultralight down quilt, stay cozy and snug tucked away from the cold. The Goose Hood can also be worn by itself when you need extra protection from the chill.
Goose Socks
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!
– Kimberly N., ★★★★★

Do not hike in these socks. Treat them as you would your sleeping bag.
