I have an extra New never used BlackHawk Hydrastorm Tidal Rave 100 Oz Hydration system. It is Black in color with the blue bungi cord. This is a great sytem to have to go hiking, cutting grass, or going to the range to have something to carry water with you. Canteens are a thing of the past. Retail on Blackhawkindustries.com is $39.95 plus shipping. I have installed a new Neoprene insulated tube cover on the system to help keep ater cool this upgrade was an extra $4.95. I would like to get $37.00 and I will pay shipping.
