When there is a decent chance your gear will get wet in the field, the technical Traverse Tv2 from Sea to Summit is the synthetic sleeping bag you can count on.

You’ll have a bit of extra roominess compared to a traditional mummy bag as the Traverse features a tapered rectangular shape. This sleeping bag has a free-flow triple-zip design so that you can close it up for warmth or open it up to ventilate. The half zip on the right side of the bag frees up your arms and allows for air flow, or the full length two-way left side zip and separate foot zip allows you to use it as a quilt.

The shell is made from a 30D nylon with a DWR treatment and has a 20D nylon lining that’s lightweight and easy to compress. Featuring a 2°C comfort rating and a -4°C lower limit, this bag has a unique WaveLoft™ construction, which is layers of looped THERMOLITE®  insulation to trap warm air, and the lining is attached to the shell to prevent tangles.

For cool weather conditions, the Traverse Tv2 from Sea to Summit is a reliable synthetic sleeping bag when performance is a priority.
