Posted over in the gear swap area also, but thought I might have more chance for a response over here. I am about to start a pack and would like to use some DX40 for the bottom. Fabric suppliers have TX, VX, WX for sale in small amounts but no DX that I can find. I am hoping some kind soul would be willing to sell me some. I would like a full yard but could accomplish my immediate goal with a piece as small as 18"X18". PM if you can help me out.
