i purchased two seasons ago and used it for a total of 20 nights. Really comfortable. Z Pack bags are really the best on the market in my opinion. Listed weight is approximately 17 ounces. This is a 30 degree bag. It was recently (see receipt) professionally cleaned. A patch was placed on the outside, again, professinally. The small tear was only 1/4 inch long but the vendor, Rainy Pass of Seattle, always uses larger patches. Refer to the Z pack web site and to the final picture of my receipt from Rainy Pass documenting both the cleaning and repair. Cost new was $ 369 plus sales tax. I am offering it at 20 % off. Currently, posted lead times for this model is seven weeks; so if you need a bag in a hurry this will meet your needs. I will ship in the same box that Rainy Pass used to ship to me. You may ask why I am selling. Because with advanced age I need a 20 degree bag even in weather that does not get below 45 degrees. I have an order in to Zpack for another bag that will meet my needs. (I invested $ 117 plus shipping for the cleaning and repair). I will include shipping in your cost.
