Sleep like a baby out there.

Hit the Pacific Crest Trail with the Therm-a-Rest Saros Sleeping Bag in your backpack, and revel in three seasons of blissful sleep. Since this sleeping bag is insulated with synthetic insulation, you won't have to pamper it in the backcountry as you would with a down bag, as it will retain its insulating properties if it gets wet. This full-featured bag is fitted with a draft collar and tube, as well as an anti-snag zipper, so you aren't struggling with your zipper after a long day of hiking. An external zippered pocket is a great place to stash a headlamp, and the adjustable hood can be cinched down to keep your dome warm throughout the night. Like all Therm-a-Rest sleeping bags, the Saros features SynergyLink mattress straps, which allow the bag to be securely attached too your sleeping mattress for a warm and comfortable night's sleep, no matter how much you roll around.

Nice bag - but returning it

  • Familiarity:I returned this product before using it

I actually like this sleeping bag. Nicely built, compacts well, good features (like dual pulls on the double zipper). But I found a bag on sale elsewhere that compacted even better than this one. Also the face port on this one doesn't seal up / close up as much as I'd like (it's a little too wide), whereas the other bag I did buy (from REI, the Lumen), had a smaller face port that sealed up better. And that REI one was on sale... but this Saros bag would TOTALLY make me happy if I received it as a gift. It is designed to be thin on insulation on the bottom (back), which made me concerned that since I sleep on a Thermarest cot, my back could get cold. Not sure tho, not tested. Again, it's built very well... I hope I don't regret sending it back!
