Designed as an easy-care durable summer quilt, the versatile synthetic Glow GwI also integrates with all Sea to Summit sleeping bags (from 2021) to boost the warmth of your complete sleep system. When the mercury climbs, treat your Glow like a traditional quilt and allow your feet and arms freedom to cool you down. When the temperature drops, cinch the draw cord tight to create a footbox and secure the quilt to your mat with the simple strap and press-stud system to reduce heat loss. Need extra versatility and warmth? The QuiltLock system secures your Glow quilt to any Sea to Summit sleeping bag for a layer of synthetic insulation that won’t slide off in the night. When combined with a down bag, your Glow quilt will help protect it from internal condensation and external moisture. Synthetic insulation excels in wet conditions and by using continuous filament insulation, the Glow quilt provides excellent long-term thermal performance and durability. Offering superior recovery after compression, it retains more loft and warmth over time. The DWR treated 30D Nylon shell and 20D Nylon lining means it’s lightweight and packable—it’s also easy-care and machine washable. For backcountry enthusiasts not so enthusiastic about a restrictive sleeping bag, the adaptable Glow quilts’ multiple configurations provide easy-care versatility for a wide range of temperatures and environments.
