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.

Relax after a long day of adventure with our inflatable pillow. Designed for ultralight hikers looking to save weight without compromising comfort, our pillow inflates with only a breath or two and features a comfortable crescent shape perfect for back and side sleepers alike.

*This Item is Non-Returnable if Removed from Packaging*

When you've gone so ultralight that you are wearing all your clothing layers to bed but still want a comfortable spot to rest your head the Zpacks Comfy Camp Pillow is the solution!

This camp pillow has ultra-soft Octa® fleece against your face, and is stuffed with multiple layers of synthetic insulation to give it resilient loft. The insulation can be removed or augmented with other gear items like a down hood and booties.

Elastic bands on the back allow you to attach it to a stuff sack, dry bag, or inflatable pillow to give your head extra lift. An adjustable shock cord band secures the pillow to your sleeping pad to keep it from sliding around.

The pillow folds and rolls to about the size of a soda can, and stays compressed with the shock cord strap to keep your packed size at a minimum.

Keep your camp essentials safe and easily accessible with our modular dual-pocket Gear Nest. Perfect for keeping your glasses, phone, and other small items organized. Drop in your headlamp to turn it into an overhead lantern.

The triangular shape preserves your headroom when sitting up on either side of the nest.

To install the Gear Nest, simply attach the adjustable hooks to the loops at the interior of our tent peaks and tighten.

All Zpacks 2 and 3 person tents should already have compatible loops at the peaks.

If your tent does not have loops on the interior, our Stick on Loops work great on shelters made with DCF or other, similar, materials.

It was great at blocking the sun and flexible in the wind. I used it for hours in a rain storm yesterday and it was so light I barely noticed I was holding it that long. I plan to bring this umbrella everywhere.

Take cover from brutal sun and intense downpours with our Lotus Ultralight Umbrella. We worked hard to develop the world's lightest backpacking umbrella. Weighing in at just 6.8 ounces it is perfect for beating the heat or helping you stay dry in a storm while still being durable enough to stand up to the abuse of a thru-hike. This umbrella will have your back rain or shine!

Add our Umbrella Holster for hands free use and our Umbrella Stuff Sack for storage.

The staff is a delight. It’s sturdy, light and easily packed. We’ve tried to think of ways that it might be improved, but we’ve come up short and will just have to keep thinking.

Our Carbon Fiber Staff allows you to support your full weight using two hands on rough terrain, while keeping one hand free on more moderate sections. This staff is an ultralight, extremely strong alternative to Zpacks Trekking Poles. It can fold down for compact packing, or can be folded to the correct height to prop up any of our tents.

The Zpacks Titanium Trail Pen is a custom made ultralight upgrade for hikers who still believe memories are made with ink, not megapixels. Lock the pen into place with our precision-engineered channel system and let your ideas, trail notes, sketches, and discoveries flow. If your gear can outlast a thru-hike, your words should too.

Comfortable for left or right-handed writing. Writes when wet! Pairs great with a Waterproof Trail Notebook!

Includes a small keyring (.02 oz / 7g) and two ink refill cartridges (.02 oz / 7g each.) Pen measures 3.25" (9.26 cm) long. Our tiny oval carabiners, or mini-S carabiners are small enough to fit the little hole on the end of the pen to clip to your pack.

The Zpacks Waterproof Trail Notebook is designed to keep your notes from the field secure and dry when backpacking. This 3" x 5" (7.6 cm x 12.7 cm ) notebook lets you jot down your ideas, drawings, or journal as you go, knowing that the waterproof covers and pages will keep your notes protected from the weather.

This spiral-bound notepad lets you easily tear out pages to leave a note for a friend, or discard no longer needed pages to drop weight as you go on a thru-hike.

Pairs great with a Titanium Trial Pen!
