Ergodyne has released a WorkSmart gear bag, the GB5155 Hi-Vis Low Profile Hydration Pack. The hydration pack is constructed with high-vis lime nylon for daytime visibility and reflective glass bead tape for maximum night visibility. Water capacity is 2 liters (70 ounces), or about 3 hours under most conditions. The hydration pack's closed cell insulation keeps water cool while an insulated bite valve helps prevent contamination. Padded, adjustable shoulder and chest straps round out the design for optimal comfort. The GB5155 Low Profile Hydration Pack comes in both Hi-Vis Lime and Black.
