Here’s the latest eye-catching release from Sierra Designs, a brand that, since 1965, have been coming up with some serious outdoor innovation. It’s a sleeping bag that’s like no other. Why? Because there’s no zip, and no poppers either for that matter. Called the Cloud 35° it’s kind of like a sleeping mat and quilt combined, a design that Sierra Designs reckon could potentially bring you ‘the most comfortable night’s sleep you’ll have in the backcountry.’
Its zipperless build features an integrated comforter that hugs you in a cocoon-like wrap. You simply tuck the flap of fabric around your shoulder and the friction with the outer parts of the bag will keep it held shut, sealing out any drafts and feeling comfortable rather than constricting.
These bags are mighty light too, with the lightest option coming in at 652g and the heaviest at 822g. More often than not, when you’re out shopping for outdoor gear, you end up sacrificing comfort for lightness and vice versa. The Cloud 35°, however, seeks to find a bridge between the two with its comfortable and feature-packed design.
Here’s a breakdown of what Sierra Designs have done with this sleeping bag, and how it could be the piece of kit you’ve been missing.
Who is the Cloud 800 35°F sleeping bag for?
If you’re a camper who likes to splay out a little bit more than you’re allowed to in a conventional mummy sleeping bag, the Cloud 800 will be right up your street. The zipperless design allows for more flexibility of movement as well less faff with jammed zips in the middle of the night. You can wrap the comforter as tight or as loose as you please, depending on temperatures and tastes alike.
Additionally, if you’re someone who has rolled off their sleeping mat one too many times, the Cloud 35° features an integrated mat holder on the rear to securely send you off to sleep.
