The WLPS tactical hydration bladder is designed for low profile hydration carriers like vest-compatible MOLLE pouches and packs.

The Widepac wide opening is ideal for filling, ice-insertion, emptying and drying the bladder. Unique technology and materials make this Source water bladder unique in its low maintenance properties: fill and just refill – water stays fresh for weeks in our bladders.

Use the Source tactical 3L hydration pack for your outdoor adventures, tactical missions or when you walk your dog. The WLPS design lets your bladder slip into any type of bag, taking up less space without impacting the amount of water it can hold. Hydration bladders have many uses, but the Source WLPS is especially useful with its low-profile design, low-maintenance features, while giving high-impact hydration support with each use.
