Unmatched Versatility

Backcountry quilts offer incredible versatility that is unmatched by traditional sleeping bags.

On cold nights, our quilts can be easily closed up to form a tight fit, similar to a standard mummy sleeping bag. Even the foot box can be closed up with cinch cords to keep the warmth in.

When the weather warms up, open up the quilt to keep you nice and comfortable. You can even adjust comfort throughout a backpacking trip as the weather changes.

Finally, use it as a simple blanket while enjoying a backcountry meal or high alpine sunset.

The beauty of quilts is that they can be adapted to suit almost everyone, in almost every situation. There's no need to have several sleeping bags for different seasons.

Superior Insulation

Each quilt is filled with 20 ounces of high-quality RDS-certified 800-fill power down (22 ounces for Long version) for amazing loft.

However, the added warmth does not compromise on size and weight. The quilt comes in at only 33 oz. (35 oz. for Long version) and packs down to just 9 x 6 inches.

What's Included?

The quilt comes with a sleeping pad strap system to easily secure it to your sleeping pad. It will keep you on your pad at night and also prevent any drafts while you sleep.

In addition, we provide a durable compression sack to keep the packed size as small as possible.

Finally, between trips, use the included mesh storage bag to properly store the quilt.
