Sierra Designs Nitro Quilt

A quilt eliminates the insulation underneath you, which is typically compressed and ineffective when you lie on it. Instead, it relies on your sleeping pad for bottom insulation, saving weight and bulk while allowing you to move more freely.

The 35-degree rating assumes you are using a sleeping pad with an appropriate R-value to insulate you from the cold ground. If you are a cold sleeper or using a pad with low insulation, you may want to pair this with a liner or sleep in warmer layers.

The hand pockets allow you to pull the edges of the quilt tightly around your shoulders, effectively sealing out drafts that often creep into open-back systems. The hide-away hood adds a layer of warmth for your head, which is particularly useful on colder nights when a beanie isn't enough.

This quilt uses 800-fill DriDown, which is treated to be water-resistant. While it is not waterproof, it resists moisture much better than untreated down and will retain its loft and thermal efficiency significantly longer in damp, humid conditions.

The Nitro Quilt is designed to drape over you rather than strap directly to your pad. The integrated hand pockets and the overall cut are intended to keep the quilt secure around your body, but it does not feature a dedicated pad-attachment system.
