Review on 🎒 G4Free Tactical Hydration Pack - Water Backpack with 3L Upgraded Bladder for Hiking, Running, and Cycling by Eric Avina

Great tank/backpack for cycling. Adjustable shoulder straps for any desired configuration. The bubble is huge, there is enough water for long rides in hot summer. The hose works very well with the cap and switch conveniently located next to the nipple. The tube detaches from the base of the reservoir for easy cleaning/emptying. And here there is a small problem. There is a very small white/clear o-ring around the bottom of the hose where it connects to the bladder. Obviously the ring is not small enough as it tends to come loose when the tubing is removed from the bladder. Since it's tiny and relatively invisible, guess what if it happens and you can't find the o-ring? As you might have guessed, the leaky hydration hose connection leaks all your precious liquid right into the pack on your back. Lack of water means death. The absence of an O-ring must also mean death. Be VERY careful when removing the tubing from your bladder and don't end up with a leaking bladder. This is the only reason why this item does not receive a 5 star rating.
