    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
    • Item #STS0159

    Underperforms, especially in the damp

    • Familiarity: I've put it through the wringer

    We've used these bags for about a year and are pretty dissapointed. My wife and I each purchased one, and so far they've been used on hikes in New England, Patagonia, New Zealand, Australia, and several other places. In temperatures of about 35-40 degrees fahrenheit they begin to feel a bit cold, partly because they're simply too big - it's hard to heat up all that air space. And despite all the hype about dry down technology, performance gets much worse in damp conditions (not rainy, mind you, simply damp or humid), with cold seeping in and dampness accumulating in the down. They become clammy in damp/humid conditions and begin to feel cold at about 40 degrees. I'm not sure if this is due to the dry down technology or the shell material, but the bag simply doesn't breath. That means that any sweat or respiration gets caught in there, and over a 3-4 day trip in damp/humid conditions moisture begins to accumulate, especially around the feet.

    I normally sleep "hot" and have been winter camping comfortably in sub-zero temperatures with bags rated to 15 degrees. My wife often sleeps a bit "cold" and needs a warmer bag. But we both had the same experience with these, feeling like they under-performed and, if there's any humidity or dampness, were almost useless below freezing. I have a Marmot bag rated to 40 degrees, with old-fashioned down. The Marmot bag cost (slightly) less, weighs less, and performs better. So think hard before you get sold on the dry-down thing, If the down can't breath and dry out, it can't loft or insulate. That, along with a too-baggy design, is problem with this sleeping 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.
