The Sea to Summit Ember Ultralight Down Sleeping Quilt is the ideal sleeping bag alternative for bike packers, backpackers, hikers, and travelers who are looking for lightweight and highly compressible insulation, without the bulk of zippers or the constrictive shape of a mummy bag. High-loft, 850+ fill power down insulation (Responsible Down Standard certified) is treated with a non-PFC Ultra-Dry Down treatment to improve reaction to moisture, retaining loft and performance in rugged conditions. The Ember Quilt was designed for multi-season use with an excellent warmth to weight ratio. In warmer conditions, the ability to easily ventilate keeps you comfortable. As temperatures drop, the drawcord footbox helps you retain warmth. The light, breathable 10D shell fabric is treated with a non-PFC DWR finish to repel moisture, while the 20D liner fabric is there to deliver pure comfort. Snap on attachment straps secure the quilt to a sleeping pad, while a drawcord cinches the base into a foot pocket. QuiltLock system means the Ember can be secured to a Sea to Summit sleeping bag for additional warmth in colder weather. The Sea to Summit Ember Ultralight Down Sleeping Quilt is available in two sizes: Regular (max user height of six feet) and Long (max user height of six feet six inches); and two temperature ratings: 45-Degree for warm weather and 30-Degree for 2-season outings. Includes Ultra-Sil compression sack. Sea to Summit products are guaranteed against defects in materials or workmanship for the lifetime of the product.
