The UpsideLuxe Sleep Sack
There is something quietly transformative about slipping into your own pristine layer of cotton, wherever in the world you happen to be.
Crafted from 100% Supima® cotton in a smooth 400-thread-count sateen weave, the UpsideLuxe sleep sack is your personal layer of pristine luxury, wherever you rest. Finished in Egret, a soft luminous cream chosen for its quiet distinction.

- Interior nighttime essentials pocket: keeps personal items close at hand
- Gusseted side: allows natural drape and ease of movement through the night
- Soft, structured top flap: comfort and coverage without restriction
- Integrated pillow pocket: secures a king pillow in place
Arrives in a matching Supima cotton sateen packing envelope (14″ × 16″) that packs flat, then folds in half to slip easily into a carry-on.

“Hotel sheets have been slept in hundreds of times before. I wanted something pristine, entirely my own, and as soft against my skin as the finest sheets at home.”

From Fellow Travelers
Each received a sleep sack to try.
“I loved using the sleep sack! I always get a little nervous in hotels and like the idea of staying ‘clean.’ I wasn’t too hot with the bed sheet and blanket over me, and slept peacefully all night. It’s wider than a sleeping bag, so there was room to move (I toss and turn). It is also plenty long. I am 6 feet tall and didn’t feel crowded. It’s not bulky, it’s easily portable, and because it has a case, it keeps me feeling ‘clean’ using it several nights or in different locations.”

“The material is soft and feels very high end, like it will hold up well for years and years. It’s very comfortable to sleep in and doesn’t make you feel confined. The zipper is seamless and is easy to get in and out of, and you don’t even notice it when sleeping. I’m always worried to wash things in fear it will change the feel of the material. I was happy to find out that when washing it didn’t change or compromise the quality of the sleep sack. I loved the little pocket. It kept my phone in place all night and I didn’t have to go searching the bed for it. It is worth the investment. It did not disappoint. I will never travel again without it!”

“I travel a lot and this sleep sack has made sleeping away from home so much more comfortable. I love having soft luxurious sheets with me wherever I go, and the fabric is incredibly soft and cool to the touch, which is perfect for me since I tend to sleep hot. I also love the little pocket for my reading glasses or earplugs. It keeps them right where I need them instead of getting lost in the bed. Such a simple thing, but it makes traveling and sleeping so much easier.”
— Kate
“I love traveling with my sleep sack. It’s so easy to pack and fits easily in my carry-on. I never travel without it. I hate sleeping in any other sheets when I travel. It takes care of me when I’m away from home, like bringing a piece of home with me wherever I go.”
