My first post in so hope I'm doing well mods ;) I have an alpkit rig7 silnylon tarp in kelp that have never been used. I bought as emergency shelter but it is too heavy and bulky for its purpose. I'm looking to trade it for an alpkit rig3,5 or similar tarp, or poncho tarp something that I can throw in my backpack and use if needed. Needs to be silnylon for weight conscious. Only trade in Europe for shipping cost reasons. Thx in advance :)
