Spring, summer, fall—sleep like a baby through them all.

As the lightest bag in the new Sea To Summit Talus Series, the Ts1 is ready to keep you comfy on all of your spring, summer, and fall adventures. Put your worries about condensation turning your bag into a damp piece of plastic to rest—the innovative 2D Nanoshell keeps the 750+ down fill dry and lofty by repelling moisture and by letting your excess heat escape out of the bag once you get warm enough. With this bag's relaxed mummy shape and larger hood, you'll be as likely to sleep with stars overhead as in your own bed.

  • EN rating is 23F for the lower limit (an average women's comfort level) and 34F for the comfort range (average man's comfort level), making the Ts1 perfect for summer, spring, and fall adventures
  • The Ts1 is stuffed with 750+ down fill so you get maximum loft and warmth when the temperature starts to drop on crisp fall nights
  • This bag is wrapped in 2D Nanoshell fabric that is incredibly breathable and water repellent so you don't have to worry about brushing up against condensation on the wall of your tent
  • The hood has been engineered to fully cocoon your head without feeling claustrophobic while maximizing loft
  • An adjustable collar inside the hood adjusts temperature levels and seals out bone-chilling drafts
  • The YKK zipper's anti-snag system prevents pesky snags when you're getting in and out of the bag
  • The relaxed mummy shape increases thermal efficiency and has a broader shoulder and larger hood than most mummy bags so you can actually move comfortably
  • The lightest in the Talus series, the regular size Ts1 weighs in at just under two pounds, making it a pleasure to pack to your favorite camping trips
  • Includes a lightweight Ultra-Sil compression bag, mesh storage cell, and laundry bag

Warm and roomy, great hood.

  • Familiarity: I've used it several times

I have only used this bag a handful of times and have been very happy with it as a 3-season bag. It is roomy, the zipper is catch free and the double synch at the face of the bag is very well designed. I recently took it on a climbing trip sleeping at about 8,000 feet, it was adequately warm even as temps dropped into the teens. I did have a down jacket on as well, but I was surprised at the amount of warmth given this bag's rating. I haven't had a chance to see how the treated down performs under wet conditions, but the outside of the bag had ice on it from condensation in my tent and the DWR coating did a great job as well. So far this has been an ideal all-in-one bag. I sleep hot usually, so if you are a cold sleeper the Talus TsII may be a good alternate.
