Great vest..nice large pockets (including 3 inside pockets), plus great ventilation system (mesh rear is covered by the cloth but has pleats allowing the air to come in easily. Nice sturdy zipper. Wore this for the first time last weekend and was able to get lenses and extra batteries and a flash unit all packed in nicely, along with a wallet for my personal needs plus has room to hang sunglasses on rings for quick removal and then access. Has pen holders, if you carry pen and paper. True to size..I wanted one large enough to go over my jacket if necessary and it fit just fine, large armholes. Some of the velcro closures are a bit hard to tug open at first, so you need to loosen those up BEFORE you start wearing the vest. Material is lightweight but seems sturdy enough.
