Our Ultralight bag is a great warm weather bag, and works well in cooler weather if you wear insulated garments while sleeping. An extremely compact sleeping bag when compressed, this European-made bag is of exceptional quality and is perfect for "going in light."
Not just a stand-alone bag, the Ultralight can be used as a liner for the Reveille, which when combined turns the pair into a good cold weather bag. If you buy both, you will be ready for any environment.
The Ultralight features Carinthia G-Loft insulation, the best synthetic insulation on the planet. The incorporated mosquito net allows you to sleep under the stars in warmer weather, while keeping the summer's bugs out.
