*Gloves are non-returnable if they have been removed from the packaging.

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.

These are absolutely the warmest socks. I take them backpacking to put on when I get into camp and they keep my feet toasty.

These socks are very thick and warm! They are rugged enough to hike in on cold days, and they also make excellent sleep socks. They are great for winter sports as well.

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.

Get ready for sweet dreams on cold nights when bundled up with the Zpacks Down Hood. A perfect companion to your ultralight down quilt, stay cozy and snug tucked away from the cold.

A down hood can move with your head as you turn side to side in your quilt, unlike an integrated mummy bag hood. You can also wear it around camp, or tuck it inside your camp pillow when you don't need it.

Zpacks Down Hoods are reversible, face whichever color you prefer outward.

This is the lightest and most comfortable day to day t shirt.

– Jason H., ★★★★★

Designed for comfort and fashion, rep Zpacks on and off the trail with our high quality soft tri-blend T-Shirt.

Material: Tri-Blend 50% Polyester, 25% Cotton and 25% Rayon

Printed in the USA.

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.

The Zpacks Octa® Fleece hat delivers impressive warmth without the bulk, ensuring you stay cozy whether you're tackling a windy trail or your morning commute.

Ultralight by design and featuring a double layer of fleece around the ears, this hat locks in heat where it matters most while remaining breathable and easy to pack. Warmth without compromise—no matter where the day takes you.

For a heavier weight 4 season option, check out our Brushtail Possum Beanie.

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.

When the morning air has more bite than your trail mix, the Zpacks Octa® Neck Gaiter has your back (and your neck, face, and occasionally your hair). This ultralight wonder isn’t just a gaiter, it’s a shape-shifting sidekick ready to tackle whatever the trail throws at you.

Need warmth? Done. Sunburn defense? Check. Bad hair day camouflage? Absolutely. Think of it as a multi-tool for your head except way softer, lighter, and less likely to pinch your fingers.
