SOURCE Upgrade Kit Hydration Bladder — Coyote

The SOURCE Upgrade Kit 3-litre hydration bladder is a high-capacity hydration system designed for extended outings: hunting, field operations, tactical hiking, or any situation where water needs to be accessible on the move. It fits virtually any pack or carrier with a hydration sleeve, thanks to its universal profile and standardised closure valve.

The bite valve features a locking mechanism that prevents accidental leaks when the bladder is under negative pressure inside the pack — a detail that matters on slopes or during rapid movement, where an unintended squeeze would release water without warning. The tube and cap follow the stated Coyote colour; the inner bladder is green, as per the standard construction of the SOURCE line.

At 3 litres, the kit covers more than a full day of moderate exertion, or half a day in hot conditions with intense activity. The empty bladder adds negligible weight to the load, but when full, those three litres translate to 3 kg of liquid — position it as low as possible in the pack to keep the centre of gravity stable.
