Custom Comfort for Camp: The Rumpl Wrap Sack 20° Sleeping Bag

Rumpl has built a reputation for taking familiar outdoor gear and giving it a seriously innovative twist, particularly with their performance blankets that redefine comfort in the wild. Now, they’ve turned their attention to the humble sleeping bag, and the result is something genuinely game-changing: the Rumpl Wrap Sack 20° Sleeping Bag.

Inspired by everything they know about layering blankets for optimal warmth and comfort, the Wrap Sack offers a goldilocks balance – less constricting than a mummy bag, yet significantly more performance than those old-school flannel rectangles. It’s the perfect sweet spot between way too much and not nearly enough, designed to let you truly customize your slumber experience in the great outdoors.

The standout feature here is the WrapAdapt™ layering system, a first-of-its-kind blanketing system integrated into a sleeping bag. This allows you to choose your comfort setting with three different ways to wrap yourself, providing granular temperature control up and down the bag for optimal sleep. It’s a simple yet revolutionary idea that moves away from the one-size-fits-all constriction of traditional mummy bags.

Beyond the unique wrapping system, the Wrap Sack is packed with thoughtful features designed for practical comfort. It includes a pillow pocket hood that integrates seamlessly with Rumpl Camp Pillows, Cape Clip® connections to secure layers or connect to Rumpl blankets for added warmth, and a full 2-way zipper panel that allows for crucial venting and freedom of movement when you need it.

Performance is naturally key. The Wrap Sack boasts a 20ºF Limit Rating and a 30ºF Comfort Rating, both certified by the ISO 23537-1 standard, ensuring it’s rated for chilly nights down to freezing. It’s designed with oversized comfort in mind, accommodating users up to 6’2″ in height. Rumpl is also putting sustainability at the forefront, crafting the Wrap Sack with 100% post-consumer recycled materials for the shell, liner, and insulation, all made from recycled plastic bottles – a fantastic commitment to reducing environmental impact.

The exterior features a PFAS-free durable water repellent finish for stain and weather resistance. Inside, RenewaLoft™ 100% post-consumer recycled polyester insulation provides a uniform warmth barrier in the shell, while NanoLoft® liner insulation mimics the warmth of down, offering high compression and rebound, and crucially, staying warm even when wet.

This genuinely innovative design, built with sustainable materials and offering customizable comfort alongside solid performance ratings, is available in a cool Baja Fade colourway. Offering all this at a price point of $199, the Rumpl Wrap Sack 20° Sleeping Bag presents a compelling proposition for any camper or adventurer looking for a more comfortable, less restrictive, and more adaptable sleep system.

It comes complete with a roll-top stuff sack for easy packing and a storage sack with a breathable mesh top. The Wrap Sack is more than just a sleeping bag; it’s a rethought approach to outdoor slumber, designed for modern adventurers who value comfort, sustainability, and performance in equal measure.
