Sea to Summit Trailhead II Long Wide Sleeping Bag

The Sea to Summit Trailhead II Long Wide sleeping bag is a versatile and comfortable 3-season synthetic bag designed for campers and backpackers who value space and warmth. With a tapered rectangular shape, it offers generous room for movement while maintaining thermal efficiency. The bag features THERMOLITE® Ecomade synthetic insulation, providing reliable warmth even in damp conditions, and a WaveLoft™ shingle construction that eliminates cold spots. The long-wide size accommodates users up to 198 cm (6 ft 6 in) with ample shoulder, hip, and foot girth.

Advantages

This sleeping bag excels in comfort and durability. The 30D DWR nylon shell resists moisture, while the soft 20D nylon liner feels great against the skin. The full-length YKK #5 zipper on the left side, plus a secondary footbox zipper, allows for ventilation and easy entry. An oversized draft tube and draft collar prevent heat loss, and an internal pocket keeps small items handy. The included Ultra-Sil™ compression sack and mesh storage sack make packing and storage convenient.
