Keep it simple on short trips away, without compromising on performance - thanks to the Trailhead Th3 Sleeping Bag from Sea to Summit.

The Trailhead features a unique WaveLoft construction that loops together thick layers of synthetic insulation to trap warm air and keep you cosy. This bag has a tapered rectangular shape allowing extra room in comparison to a traditional mummy bag. For a compressible and lightweight design, the shell is made from 30D DWR nylon while the 20D nylon lining attached prevents any tangling.

When the weather is warm, simply open the full-length side and foot zip for use as a quilt, or ventilate by opening the zip slider in the footbox. There’s nothing more annoying than your zipper getting caught - so the anti-snag, oversized zip draft tube puts that bother to bed. Its -1°C comfort rating and -7°C lower limit has this sleeping bag ideal for chillier nights out at the campsite.

When you want technical features bundled into an uncomplicated design, enjoy the Trailhead Th3 Sleeping Bag from Sea to Summit.
