Do Your Sleeping Bags Get Heavier Over Time?
My first nice sleeping bag was a Western Mountaineering Highlite that I didn't take the best care of and it gained a significant amount of weight in what I assume is dirt over the years and had some trouble staying lofted. It was 15 oz when I bought it, and 20 oz when I replaced it.
I currently have an EE quilt that I've been much better about keeping clean and throwing the dryer whenever I have a chance to help it last as long as I can. I've had it for two years, used it about 150 nights, and have washed it with down wash several times. It's up from 14 oz to 16 oz.
It's less about the weight and more about that there's clearly still filth in my bag that's going to interfere with the loft and durability of the bag. Does anyone have any tips other than washing it more to get the dirt out of the down?
