SEA TO SUMMIT TRAILHEAD TH II 2019
The perfect feature-packed, value oriented synthetic bag for weekend warriors and new campers, Sea to Summit's Trailhead is no slouch when it comes to performance. It’s tapered rectangular shape provides more space and comfort than a traditional mummy bag while the full-length side and foot zip allows the bag to be opened out and used as a quilt. A second zip slider in the footbox provides extra ventilation and versatile temperature adjustment. Our unique WaveLoft™ construction uses thick layers of insulation looped together to gain extra loft and trap pockets of warm air, providing increased warmth in colder conditions. The baffle construction also eliminates the frustration of getting tangled in loose lining as all lining fabrics are attached to the shell fabric.

Waveloft Construction

WaveLoft™ is a unique construction technology designed to maximize loft and minimalize insulation weight. Instead of conventional flat layers of insulation (sewn flat on top of each other) or shingle layers (sewn in diagonally overlapping layers), WaveLoft™ creates curved layers which expand out from the shell to trap the greatest amount of air possible at a lower overall weight than existing synthetic insulation constructions.
