Problem with a lot of the fillers used in Jkts, and Bags is that when the were shipped to the manufactures of the bags, and jkts, they are glued, and compressed into sheets. Once they have been washed clean of the glue they are then cut and put inside of the bag or jkt being made.. because of this most fillers loose between 10 to 30% of their insulating properties.. and after washing they can loose again the same %s. I try to go with companies that make the fillers them selves.. and keep away from the others.. and I only wash something when I have no other chose.. as can be seen above you guys had no chose, and my kids have done the same to me. I think the Nikway is a very good way to go.. and sometimes I just was in the machine at 30º and let air dry.. or the most painful thing is just throw it away, or wash it and use it for something else.. If you use your kit oftern, and have it for a couple of years, then it's probably best to re-invest into another one.. I sometimes, find myself going back to a shop, and buying a second piece of kit once I've found something I love, and works great, just for the fact of my loosing it or it getting too dirty.. and that way, I don't have to re-invest in trying to find something that deosn't excist anymore... I know too expencive.. but I learned once that sometimes two is better then one, when my daughter threw out her stuffed Rabbit on a trip to town one day when she was two years old, and I didn't get any sleep that night.. I went out and bought two new rabbits but couldn't find the same model..
