Rteq™ insulation is a proprietary blend of 4 unique polyester fibers, each chosen for its specific characteristics of denier, loft, weight, and thermal efficiency. This advanced blend provides the perfect balance of warmth, durability, and compressibility that make Eureka! bags the ideal choice for users who need a lightweight bag and minimal pack size!
The warm-to-touch, peached polyester lining combines the performance value of a synthetic fabric with the soft feel of cotton. The slightly fuzzy texture provides added warmth and comfort in any condition.
