This may work for you also, but I find that cheap ones work best for me and I tend not to wash or clean them and as they start to get all clogged up the become soft and more quiet as time passes, I usually have a couple of pairs one I use for stalking the other I use or more to the point using up ready for stalking.
Hope that helps, Blacks outdoor shop have ones costing as little as 8 pounds and I tend to have them as tight as they will fit around my legs to stop them rubbing.
