Tactical Hydration Backpack — 3L Insulated Water Pack
Highlights
Three litres. Zero hands.
Insulated to stay cold for hours.
Ballistic nylon, built for abuse.
Carries big. Weighs almost nothing.
Hydration, engineered for the long way round.
Most packs make you choose: carry enough water, or move freely. The OHEN Tactical Hydration Backpack refuses the trade. A full three litres rides flat against your spine in an insulated sleeve, while the low-profile shell disappears into your silhouette — on the trail, on the bike, in the crowd.
Every gram is accounted for. Ballistic nylon where it takes abuse, ventilated mesh where your back needs air, MOLLE webbing where your gear needs a home. Fill it, clip the tube to your strap, and forget it's there until you're thirsty.

Precision-built for the trail
The shell is rugged ballistic nylon with reinforced bar-tack stitching at every stress point. MOLLE webbing across the face takes carabiners, pouches and lights — so the pack adapts to the day, instead of the other way round.
Built to disappear on your back.
Sip without breaking stride
The 3L food-grade TPU bladder feeds an insulated drinking tube that routes over your shoulder and clips to the strap. A leak-proof twist cap seals the top; the bite valve opens with a squeeze and closes the moment you let go.
Water when you want it. Not a stop in sight.

Questions, answered.
The things people ask before they buy.
How long does water stay cold?
The bladder sits in an insulated sleeve that keeps water noticeably cool for hours, even in direct summer sun. For the coldest result, start with chilled water or drop in a few ice cubes before you set off.
Is the bladder safe to drink from?
Yes — it's made from food-grade, BPA-free TPU. Give it a rinse before first use and there's no plastic aftertaste.
How do I clean it?
Rinse the bladder with warm water and a drop of mild soap, then hang it to air-dry fully opened. Flush the tube through after anything other than water, and it stays fresh with almost no upkeep.
What is it best for?
Hiking, cycling, running, festivals and long days out — anywhere you want water on your back and your hands free. The MOLLE webbing also makes it a capable lightweight day pack.
