Are you a restless sleeper? Or, much 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.” If you’re the kind of traveller that likes a bit more room to move than the Sea to Summit Trek WTkI is the one for you.

The bag incorporates highly breathable 2D PermaShell™ fabric which will keep your down in tip top shape. The tapered rectangle design makes the Trek ideal for people with a larger frame or who prefer a roomy bag. The full-length side and foot zips mean you can zip it wide open and use it as a quilt for balmier nights, or have your feet poking out if you need some air flow while you sleep. And, in colder weather, the two-dimensional hood is will help trap warmth for a soundless night’s sleep in the elements.

The length of this bag is reduced for a closer fit, and the hip area is widened for added roominess for a women’s specific fit. The women’s model also comes with two combined down and Thermolite synthetic baffles under the foot area which will keep your heels and ankles warm in the area where feet can compress the down.

Featuring an oversize internal pocket that’s big enough to keep your wallet, passport, and gadgets close while you doze. The included lightweight Ultra-Sil® compression bag will compress the bag down to a mere 6L for easy packing. Designed for the globetrotter who’s chasing the perfect balance between space and a tapered fit - the Trek TkI from Sea to Summit gets it just right.

Is there a long version available for this bag?

G'day Adi,

Unfortunately as the women's sleeping bag range is still quite new, there isn't a long version presently available.
