Lighter than a similarly rated sleeping bag. No squirming around to get in and out. Easy to vent for temperature control. The Jacks’ first down quilt, the “Old Rag Mtn” is a true winter quilt capable of keeping a sleeper warm down to single digit temperatures. “The Old Rag Mtn” was specifically designed for use as a top quilt with a foot sack capability and can be used either on the ground or in a hammock. It will also function as a hammock under quilt (JRB Suspension System sold separately). For individuals over 5 feet 10 inches tall we offer a long version (86″ in length).
Activ-dri down™ – Activ-dri™ is a hydrophobic down treatment that keeps the down drier, while having no adverse effects on loft, fill power, or warmth retention. Activ-dri down is still down insulation and should be protected from direct exposure to moisture. All types of insulation, whether down or synthetic, will degrade in insulation capability if wetted.
