Portland’s own Rumpl first changed the cozy camp game with its light, yet powerfully warm Original Puffy Blanket in 2014. More than 10 years later, the brand finally decided to tackle the camp blanket's more worthy adversary: the sleeping bag. The company's new Wrap Sack ($199) is built for three-season comfort down to 20ºF in a roomy, rectangular shape that hides a unique WrapAdapt layering system, which unzips and unfolds from its otherwise unassuming, conventional look.
While the debate over quilt vs sleeping bag moves from niche the ultralight backpacking community to mainstream conversation, Rumpl leaned into its car camper customer by designing the Wrap Sack to prioritize comfort and practicality over weight and high-alpine warmth. Filled with NanoLoft insulation inside and RenewaLoft 100% post-consumer recycled insulation outside, the Sack should offer enough warmth on deck for most campers during the regular season of outdoor sleeping.
For the past six months I've had the opportunity to test a pre-production model. I've since put it through its paces, dutifully spending nights and afternoons swaddled and snoozing in both rooftop and ground tents. It's a hard job, but someone's got to do it. Keep reading for my full review.
How the Rumpl Wrap Sack Actually Works
The most notable feature of the Wrap Sack is the two winged panels that make up its so-called WrapAdapt layering system. The sleeper can unzip the top panel in full or in part to removes a layer of insulation and manage warmth. Underneath, the second panel can loosely fold over the body or be secured by several Cape Clip closures—a feature borrowed from Rumpl’s Backcountry Puffy.
On a moderate evening hovering just below 60ºF, I’d usually begin a night's sleep with just the single inner layer draped over me–sometimes clipped tight, sometimes not. As temperatures dropped, I could easily throw the second layer over me.
I assumed that my close-fitting mummy bag would be warmer than the Rumpl Wrap Sack, but I was pleasantly surprised by how well the latter performed on colder evenings below 50ºF last fall and early this spring. As long as I started the night with both layers closed, I had no issue falling asleep. And I appreciated the fact I could adjust the outer or inner layer to shed excess heat throughout the night. It's much harder to do that with my mummy bag.
Primary Considerations: Size and Weight
Unpacked, the 35” x 82” size provided my 5’8” frame with ample space to toss, turn, and roll around throughout the night without getting twisted up. It should even work well for someone up to 6’2” comfortably.
Stored in its stuff sack, the Wrap Sack packs down to a manageable 8” x 17.5”. I had no trouble storing the Rumpl Wrap Sack in one of my favorite gear bins during car camping outings. It may also fit in an extra roomy pack, but the 5-pound carry weight makes it a less than ideal choice for backpacking.
Who Is the Wrap Sack for?
The Rump Wrap Sack is ideal for car camping—for sleeping in big tents and prioritizing comfort and coziness over size and packability. It feels much more like the platonic ideal of a sleeping bag you would have seen in TV shows and movies than the mummy-style bags more hardcore campers tend to prefer for their packability and lighter weight.
If you're a new camper just getting started, with no immediate plans to backpack, the Wrap Sack is a flexible, comfortable option from a reliable company. In fact, it might just be the ideal gateway product for those looking to get more comfortable sleeping outdoors.
Should you decide to try backpacking or bikepacking, you can always upgrade to a more serious bag. But assuming you have no interest in pouring over specs, the Wrap Sack is a good starting point.
Final Thoughts
As a brand, I think Rumpl knows it’s holding down the camp blanket space. It has backed up the success of items like Original Puffy Blanket with pieces like the reworked Backcountry Puffy. The Wrap Sack is evidence it has figured out how to leverage its blanket know-how to design a great, basic sleeping bag. And honestly, unless I’m rationing finite pack space, the Wrap Sack is likely to be the bag I roll out in my rooftop tent, car camping tent, or mattress of an untrustworthy motel.
