Instead of using their super-strong airbeams, Nemo has found something even stronger to support your shelter: an MRAP.

Nemo’s newest bivy, called the Magbag Shadow SE 1P, has a set of detachable rare earth magnets that attach to the undercarriage of suitably tall vehicles to create a 27-inch-high, 1-person tent. If you can’t find a vehicle to shelter beneath, the Magbag works just fine as a traditional, unsupported bivy. The new M-ATVs are low-rider low (for an MRAP, anyway) at 13.4 inches, and aren’t tall enough to work with the Magbag.

The Magbag is made from 40 denier “OSMO,” Nemo’s proprietary waterproof/breathable tent fabric, and has two doors, one large one on the side and another on the front. The doors can be made with mesh fabric for ventilation. It’s 2.5 pounds and comes with a stuff sack, stakes, magnets and a repair kit. Dimensions are 89 inches long x 27 inches tall x 31 inches at the head, tapering to 25 inches wide at the feet. It’s a mil-only item available through ADS for about $249. Just don’t try and use the Magbag under a moving MRAP until Nemo releases the matching, quick-attach Kevlar footprint.
