Sea to Summit Trailhead Synthetic Sleeping Bag 30

The Sea to Summit Trailhead Synthetic Sleeping Bag 30 is the men's-specific version of the synthetic Trailhead mummy line, tuned for milder temperatures. EN 13537 testing gives a comfort rating of 4°C, a limit of -1°C, and an extreme rating of -16°C — a typical spring-to-summer bag for lower elevations. At 1,040 g it sits closer to a standard camping bag than an ultralight one. Insulation comes from WaveLoft synthetic fill, which tolerates moisture better than down and needs less careful handling. A full-length, two-way left-side zipper with a draft tube allows on-demand ventilation, while a 30D shell and 20D nylon liner with a DWR finish add abrasion and moisture resistance. It compresses to a 32 × 18 cm stuff sack, roughly 7 L. Cut for a shoulder width of 76 cm and foot width of 51 cm, the bag is sized for men up to 182 cm and cannot be zipped together with a second bag. Given the weight-to-warmth trade-off, it suits camping and easier hikes better than lightweight multi-day trekking.
