Sea To Summit Traverse Synthetic Sleeping Bag GreenWhether you hike through snow to sleep in an alpine hut or camp out after a summer storm, the Traverse wont let you down.

Whether you hike through snow to sleep in an alpine hut or camp out after a summer storm, the Traverse won’t let you down. Our unique WaveLoft construction uses thick layers of THERMOLITE® insulation looped together to gain extra loft and trap pockets of warm air, providing increased warmth in colder conditions. The baffle construction also eliminates the frustration of getting tangled in loose lining as all lining fabrics are attached to the shell fabric. The Free-Flow triple-zip design ensures your sleeping bag retains maximum warmth and efficiency when needed and multiple ventilation options when it’s not. The half zip on the right side of the bag provides freedom of movement for both arms, additional ventilation and means the top third of the bag can be folded down as a mini quilt. The full length, two-way left side zip and separate foot zip transforms the bag into a full quilt for when the mercury climbs higher than expected.

FEATURES

  • Tapered rectangular shape for more space and comfort than a traditional mummy bag
  • Free-Flow half right side, full length left side and separate foot zips for freedom of movement and increased ventilation
  • THERMOLITE® insulation using WaveLoft construction for extra warmth and loft
  • Lining fabrics attached to shell prevents tangles
  • Proprietary blend of THERMOLITE® insulation using soft microfibres and fine denier hollow-core fibres for lightweight warmth and softness, with high loft and superior compressibility
  • Anatomically shaped footbox for extra space
  • Oversized anti-snag zip draft tubes and neck draft tube
  • 30D DWR Nylon shell and 20D Nylon lining are lightweight and very compressible fabrics
  • Includes strong 70D compression sack
  • This bag is designed to pair with another
  • All fabrics and treatments are non-PFC

so far so good
I was surprised at this pair of pillow cases only because the material seemed impossible to be cooling - it's that weird polyester blend. So far I have not awoken feeling sweaty around my face and scalp. I don't recall what I originally paid but I think it is great value for money! If you are sensitive to out of the box smell, I washed mine first and it didn't impede on the efficacy of the cooling!

It’s like sleeping on a beach in San Vito lo Capo
Italian voice: I’m a big meaty fella so I put off a lot of heat ya hear. These pillow cases have changed my life. One moment they’re hot and the next you flip them and you’re blasted with a blast of ice cool what it feels like to chew 5 gum feeling capeesh. I would reccomend these pillow cases to even my grandma. If ya wanta get a rest so good that it feels like ya been sleeping with the fishes get these pillow cases, they’re the real deal. Then stop at Pauline’s joint and grab a slice of pizza say Vinnie sent ya. Anyways I gotta go my wife’s cooking up a mean lasgna and we’re gonna watch the dodgers. Let me know how these treat ya I guarantee they will change your life. Vinnie out

Soft "cooling" case.
Yes it is very cool when you lay on it. It doesn't stay cold though. Within a minute or 2 to whatever your temp is.

Great for hair and skin. Great buy.
These pillow cases are great for my hair and skin. They look good, hold up well in the washer and dryer, and the price is great. They are cooling. Of course I wish they could be more cooling, but honestly I'm not sure that's even possible. Great pillow cases. Already bought more for other heads. Would buy again.

Hot hot hot. Side sleepers will hate it
At first touch, these are the coldest pillowcases I own … but only for seconds. Once you actually lay on them, within seconds they adjust to your body temp, the heat feels trapped, my head begins to feel hotter than before I laid down - which has in turn caused me loathe these pillow cases. I hate that I have missed the return window. Would never buy again, would never recommend. My satin ones aren’t even this hot! I gave them the good ole 30-day try. Side sleepers - if you are like me and sleep on your side with arm tucked under pillow - flipping this pillow over in hopes of a cold side - forget it, it’s already hot from your arm.
