  • how can I order a left hand zipper?

    • Hello olestock, this item is awesome! We do apologize, this item is not currently in stock for ordering a left hand zipper style. Thanks for shopping with us! -Amanda P

  • I would like to know if the Down is also treated for moisture resistance. Treated down holds 30% less moisture then untreated. When you tucking your head in a sleeping bag when it's cold this can make a huge difference with a down bag.. Thank you.

    • Hi cmpngmom, we were able to verify this information with our support team. The actual down is not treated for moisture resistance. We hope this helps. Thanks for shopping with us.

  • What's the weight of this bag and packed dimensions?

    • Hi sschultzy, this bags shipping weight is 5 lbs. It will be approximately 14 inches L x 13 inches in diameter. Thanks for your interest, hope this helps!

  • Is diamond tech nylon (outer material) waterproof, water resistant, breathable ? Is 800 super downX on top of bag only? please describe down baffle system. thank you DD

    • Thank you for your question. The down is on the top and sides of the bag. Baffles are vertical walls of fabric sewn inside the goose down bag. Baffles provide depth to the down bag and keep the goose down in place. When goose down settles, cold spots occur. Baffles secure the goose down filling and help it stay evenly distributed. I will find out if the material is water proof or not.

    • Hello, These bags are not waterproof. We make them with Diamond Hi, Hi, TACTEL high thread count Micro-Fiber for the shell. TACTEL MicroFiber fabric threads and filaments are tightly packed so air spaces are few, and too small for wind and rain to breach, yet still breathable. Each fiber is also treated separately before it is stitched which helps with the wind and water resistance. They are considered water resistant in most cases, but will not keep the water completely out in something like a flooded tent or something like that. Have a great day!
