Zeolite Running Vest, I've been watching this since the beginning of the year waiting for a better price.
At $124.99 it's much cheaper than comparable products from Salomon, CamelBack etc.
Weighs 260g, Includes soft flasks (many alternatives don't), 12L volume capacity. Does not include a 2L bladder.
Lots of positive reviews on Kathmandu's site. I was able to combine with a $20 birthday voucher.
