I've recently fallen in love with using a top quilt and am selling my Marmot Helium 15 as well as my Mountain Hardwear Phantom Spark 28 sleeping bags. Marmot weighs in at 2lb 1oz and MH at 1lb 6oz. Both of these are in great condition. The only flaw I am aware of is that the temp rating printed inside the Marmot has peeled. Both bags still have great loft as they have always been kept in their large storage bags in a non smoking house when not in use. Storage bags are included as well as the stuff sacks that came with the bags. I'm asking $300 for the Marmot and $175 for the MH. I accept Paypal and Venmo for payment and will cover CONUS USPS shipping. Happy trails!
