For warm weather I bought an Alps Long Spur vest - the version without the seat. I added my own seat to it. It's really just a webgear vest with a fanny pack and front call cases. I used it this fall over a heavy coat. I used it last sring, in May, when it was hot. It's much lighter than my other full turkey vests. I'll probably just stick with it. I can get water, snacks and all y calls in it, and still have room to zip up my pohone, wallet and keys.
