Sea to Summit Trailhead III Regular Wide Sleeping Bag

The Sea to Summit Trailhead III Regular Wide sleeping bag is a versatile 3-season synthetic bag designed for campers and backpackers who value comfort, durability, and eco-friendly materials. With a relaxed mummy shape and generous girth, it offers ample room for side sleepers and those who prefer a less restrictive fit. The THERMOLITE® Ecomade insulation provides reliable warmth even in damp conditions, while the WaveLoft™ construction maximizes loft and heat retention. The included Ultra-Sil Compression Sack allows for compact storage.

Advantages

The THERMOLITE® Ecomade fibers are partially recycled, reducing environmental impact without sacrificing performance. The WaveLoft™ baffle construction prevents cold spots and ensures even distribution of insulation. The left-side zipper features a draft tube to minimize heat loss, and an internal pocket keeps small items handy.
