Sea to Summit Trailhead Sleeping Bag

Yes. The full-length zipper wraps around the foot box, allowing you to unzip the bag completely and lay it flat. This makes it a versatile option for warmer nights or for campers who prefer the feel of a comforter over a traditional mummy bag.

With a 20F temperature rating, this bag is designed for 3-season use. It should keep you comfortable in cool to cold conditions, though if you are camping in temperatures consistently near or below freezing, you may want to pair it with a high-R-value sleeping pad to prevent heat loss from the ground.

WaveLoft construction allows the synthetic insulation to expand into curved layers, which traps more air than standard flat insulation. This design helps maintain consistent warmth throughout the bag without adding unnecessary bulk.

Absolutely. The Trailhead features a tapered-rectangular shape, which offers more shoulder and hip room than a traditional, restrictive mummy bag. It provides the thermal efficiency of a mummy bag while giving you enough space to shift positions comfortably.

The shell is treated with a PFC-free DWR (Durable Water Repellent) finish, which helps it shed light moisture, condensation, and morning dew. While it will protect your insulation from damp tent walls, it is not fully waterproof and should not be used in heavy rain or exposed conditions without shelter.

The Regular size compresses down to about 10.2 liters, while the Long size is roughly 12.1 liters. It comes with a 70D nylon compression sack, making it easy to cinch down and fit into most standard backpacking packs.
