Needed something for Long Distance motorcycle trips on hot humid days. It’s external fill meaning it’s SUPER easy to access, fill with ice and water and go. (No wasted time pulling the bladder out, filling and stuffing it back in). Note: it’s not a cooler, so on 80-100 degree days you must mix your ice. If not, you’ll just end up drinking warm-hot water.

Excellent quality, durability and functionality. The size/weight/capacity are perfect for me as I wanted hydration only. No need for storage.

not too heavy as well as very easy to carry!

Great craftsmanship.

Newer 2019 Stealth version that comes with the 85oz/2,5L Mil-Spec Crux reservoir holds 15oz more water than the previous 2013 Mil-Spec Antidote 70oz/2L model. Still maintains the sleek low profile aspect of its design to use in tight confined spaces such as a vehicle or aircraft. Able to route the hydration tube over the shoulder or under the arm for left or right side. Easy external access to the fill port with dual zippered flap. Like the previous versions I could use this under a jacket or vest. When I was Active Duty, I used mine under my Flotation Vest while working on the Flight Deck of an Amphibious Assault Ship to stay hydrated during long flight deck operations. Only Con I have is that it only comes in Black. I would love to have a Coyote and an Olive Drab version of this model as available color options.
