Designed as an easy-care durable summer quilt, our versatile synthetic Glow GwI also integrates with all Sea to Summit sleeping bags (from 2021) to boost the warmth of your complete sleep system. Ideal for use in humid and damp climates and a great option for a lightweight bivi set up.

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 foot pocket and secure the quilt to your mat with the simple strap and press-stud system to reduce heat loss.

Synthetic insulation excels in wet conditions and by using continuous filament insulation, our 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, our adaptable Glow quilts’ multiple configurations provide easy-care versatility for a wide range of temperatures and environments.
