Keep it simple on your quicker trips away without compromising on performance with the Trailhead Th3 Sleeping Bag from Sea to Summit.

This bag has a tapered rectangular shape which gives you extra room compared to a traditional mummy bag. The Trailhead features a unique WaveLoft™ construction which loops together thick layers of synthetic insulation to trap warm air to keep you cosy. To make it compressible and lightweight the shell is made from 30D DWR nylon while the 20D nylon lining is attached to the shell to stop it getting tangled.

When the weather is warm, just open up the full-length side and foot zip to use it as a quilt, or ventilate by opening the zip slider in the footbox. There’s nothing more annoying than your zipper getting caught, which is why the oversized zip draft tube has anti-snag, while the -1°C comfort rating and -7°C lower limit makes it ideal for colder sleepers or chillier nights out at the campsite.

When you want technical features wrapped up in an uncomplicated design, grab the Trailhead Th3 Sleeping Bag from Sea to Summit.
