The review team at WIRED® had a chance to test the Geigerrig Hydration System in the RIG 500 Ballistic pack on a 14-mile run up Kanaka Peak in Northern California. Once again, the Geigerrig performed beautifully.

“This is a huge win for me, personally. I’ve been out of water and dehydrated on long runs, crossing streams without daring to drink the water I was wading through,” writes WIRED gear reviewer Billy Brown.
