Sierra Designs, established in 1965, is a leading provider of outdoor gear and apparel, dedicated to creating functional products to enhance outdoor experiences. We believe that everyone should have access to outdoor adventures, allowing them to embrace exploration, cherish special moments, and break out of their comfort zones. Our innovative and accessible gear is designed to encourage people to Think Outside and find joy in the adventure itself.

Our zipperless technology, featured in products like the Cloud sleeping bag, incorporates a full-sized integrated comforter and insulated pockets, providing unparalleled comfort for a good night's sleep in the backcountry. The self-sealing foot vent allows for temperature regulation, mimicking the feeling of being at home, while the integrated pad sleeve ensures that the sleeping pad stays in place, allowing for undisturbed sleep.

Featuring PFC free DriDown insulation, our products are treated with a hydrophobic finish, ensuring that the down remains dry, lofted, and dries quickly. Sierra Designs was the pioneer in zipperless sleeping bags with the Backcountry Bed, and our sleeping bags continue to provide campers with a more comfortable alternative to traditional sleeping bags, promoting better sleep with reduced restrictions.
