Details & Specs
Are you a bit…broader in the shoulder? Or, like George Costanza, you don’t like to be too constricted when you sleep. “I like to be able to take the blankets and swish them and swirl them.” The Sea to Summit Trek Tk1 is the sleeping bag for the traveller that likes a bit of extra room.
The Trek Tk1 has a tapered rectangular design which provides extra room compared to a mummy style bag. To keep the weight down and ensure that it’s compressible, the shell is made from durable 30D nylon, with a soft and breathable 20D nylon lining. To keep you warm, the Tk1 is filled with RDS certified 650+ Loft ULTRA-DRY Down which provides compressible insulation.
To prevent the zip getting caught, there’s an oversized zipper draft tube and this bag has vertical chest baffles help stop cold spots and down migration. When the temperature rises, open up the full-length two-way side zip and separate foot zip and use it as a quilt. If it’s a chilly night, you can just zip it up and draw in the 3D hood to trap extra warmth.
You can also keep track of essentials such as your phone or headtorch by storing them in the internal security pocket. Be comfortable and get a great night’s sleep on your adventures around the globe with the versatile and classic Trek Tk1 Sleeping Bag from Sea to Summit.
