Our latest low profile hydration reservoir design, conceived for ballistic vest integration, holds 2L inserted in ballistic vest, 3L in a pack. Maximum utilization of our low profile technology reduces the depth of the carrier, making it a truly low profile hydration system.
The bladder's design allows it to take up very little room, and it has no plastic taste. Very well built. The universal tube adapter is a brilliant accessory too. As a 3L bladder it doesn't fit all that well in smaller bags, but for the price it's more versatile.
