I recently acquired some of this gear with the intent to use it when I play paintball. I had the opportunity to test it out last weekend (23Feb08) here in Montana during a half-day session of paintball. This gear held my extra paintballs in short pods (I carried 5 pods, an extra full-sized hopper, a 20oz CO2 Bottle, a squeegie and some marker oil.) I was able to run, crawl, etc. with no problem. The items are made from a cheap looking (cotton?) canvas material that is sturdy - but would probably become pretty heavy when wet. This is a self-contained setup - a large field pack and various pouches and bags on a web-belt with suspenders. The price is very affordable - and while I acquired my set elsewhere it is available here on Ebay.
