Person sitting next to a dog in an Alpha Direct Sleeping Bag Liner

Lightweight, breathable, & compressible.

Made with Polartec® Alpha™ Direct fleece, the AlphaDirect Fleece Liner punches well above its weight. It only weighs 6oz and is highly compressible, highly breathable, and quick-drying, all while adding 5–10°F when added to your sleep set up.

Use it on its own as a packable layer for travel or add it to your sleep set up for extra warmth for nights under the stars.
