Ultralight Sleeping Bags & Quilts

Our Summer Quilt is designed with just the right amount of warmth for summer nights when the forecast is above freezing. This bag is so light, and packs down so small it can easily be tucked in your day pack just in case, or achieve an unbeatable base weight on longer summer trips.

Combine this quilt with our Zpacks Down Jacket and an Octa Fleece Hat to boost the warmth even further when needed.

The summer quilt closes with a snap at the center and at the neck for easy venting on hot nights. Shock cord can be cinched at the neck to seal out drafts.

The Summer Quilt is also compatible with our Sleeping Pad Quilt Strap (sold separately) which allows you to snap it to your sleeping pad to keep it tucked and in place.

When sub-freezing weather rolls around the Summer Quilt springs back into action as a Winter Liner. It works well as an additional layer to push the limits of your three season sleeping bag further into the colder seasons. It fits well inside any of our bottom zipper or side zipper sleeping bags, quilts, and mummy bags.

If you can only own two sleeping bags, combine one of our 20F (2.5" loft) bags and a 40F (1.25" loft) Summer Quilt / Winter Liner to keep you comfortable nearly year-round by layering as needed.

A Zpacks Slim DCF Roll Top Dry Bag is included! A $30+ value!

Our Summer Twin Quilt is designed with just the right amount of warmth for couples on those summer nights when the forecast is 40F (4C) or above.

Some couples may be able to push this quilt down to freezing by combing it with our Zpacks Down Jacket and an Octa Fleece Hat and by sharing more body heat compared to separate sleeping bags.

Crafted with ethically sourced water-resistant goose down and soft lightweight shell material, our Summer Twin Quilt easily beats the weight, cost, and warmth of two separate sleeping bags when adventuring with a partner.

Includes a Free size Medium Zpacks Roll Top Dry Bag to pack it in! A $39.95 value!

Don't forget to add Sleeping Pad Straps to lash your pads together and block drafts from below.

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.
