Traditional comfort and value, with an 'out there' design approach. The roomier Trek™ Series sleeping bags are what we grab for globe-trotting adventures on a budget.
As well as other thoughtful design features, we have included a large internal security pocket, perfect for keeping valuables close or batteries warm.
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. Then the TK1 is filled with RDS certified 650+ Loft ULTRA-DRY Down for superior insulating power.
Vertical baffles over the chest section ensure the down insulation cannot migrate or shift during sleep, creating cold spots. A side block baffle construction maintains the 60/40 fill ratio, keeping more down on the top of the bag for maximum insulation. 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. The foot zip is perfect for extra ventilation or to provide freedom of movement for your feet.
The oversized zipper draft tube uses anti-snag materials to prevent the zipper catching and the soft-touch 20D lining fabric is highly breathable yet also down proof.
All Sea to Summit Down Sleeping Bags use Responsible Down Standard (RDS) certified down.
