For many of us, resting easy in our own homes is tough enough.

Take that quixotic quest outdoors and, as romantic as sleeping under the stars sounds, the difficulty doubles.

But the next time a friend invites you to camp, think twice before bailing on account of fitful sleep.

Because Rumpl’s smart and feature-packed new sleeping bag, the Wrap Sack 20°, just might lay even your most ardent excuses to rest.

Layer cake

One of the toughest things about getting comfortable in a sleeping bag is that typically, your body parts are either in or out of it, making it hard to keep them at an optimal temperature.

That’s why the breakthrough feature of the Wrap Sack is what Rumpl calls its WrapAdapt Layering System.

Securing the chosen layers once you doze off are the brand’s Cape Clip Connections — just one instance of how the Wrap Sack maintains the comfort that enables you to snooze in the first place.

Instead of offering just one layer on top, the bag has two butterfly wings (see GIF above), letting you choose the level of insulation you need based on current weather conditions.

A second notable example is the Pillow Pocket Hood, which helps hold a compatible Camp Pillow in place.

Yet another thoughtful touch is the Two-Way Zipper Panel, enabling you to let your feet breathe while the rest of your body is securely zipped into the bag. (For some of us, this writer included, that might be the real game changer.)

Of course, none of these features would matter much if the bag itself were made of inferior materials.

Thankfully, that’s not the case at all. The shell insulation is made of RenewaLoft, while the liner and blanket insulation is NanoLoft, two proven synthetic down alternatives that are 100% post-consumer recycled polyester.

The machine-washable bag also has a PFAS-free DWR treatment for water and stain resistance.

The extra-wide design measures 35″ by 82″ and should comfortably fit users up to 6’2″, with the best use cases being tent camping and vehicle-supported camping during the spring, summer and fall.
