Eighty Days Tactical Hydration Pack and Multitool, 2 Liters (70 Ounce), Black

I've been using this as my day bag, as I have the opportunity to walk or bike to work every day.It holds quite a bit, and the bladder pack stays cold (environment plays a factor).I don't give a 5 because the tube has a on/off switch which only seems to work. I experience leakage even if the bitevalve is "turned off", but it's drop[s]; so not a big deal for me.

Tastes like plastic in the pouch if you leave water in it.I try to use as cold water as I can to not warm up any of the plastic into the water. The included tool card is neat but has been useless so far. Just makes more trash to include a thing most people won't ever use. Wish they'd use that to make better bladders that don't taste like plastic instead. I doubt this stuff is BPA-free

So far I have used the pack twice, it's a nice size to fit some bike repair tools in and some snacks if I need them. The hole in the hydration pack is large enough to stick ice cubes through to keep the water cool if you're out for a longer time. The pack itself is a bit annoying to clean, if you don't have some kind of fishing wire and cottonballs to clean the tubing then there will be a little bit of water stuck in it for a few days.

Really like the hanging hooks for the water bag. Not too excited about the water bag itself. No matter how much we tried, the bag leaked. And the bag can't be emptied completely.

IT LEAKS! BADI took this hiking for three weeks across the Western US. It leaked at the Grand Canyon. It leaked in Vegas. It leaked at Zion. Gushing water everywhere. The mouthpiece was not of a durable build and it also broke on the last day of the trip. We were careful with it, and still everything kept getting wet.

Just took my pack camping. I'm amazed by how much I was able to fit inside! Well made, comfortable to wear. I even popped out the little multi-tool once or twice to use... didn't end up needing it, but I had it, just in case!

make sure you have a clear understanding dimensions of this bag. it is VERY SMALL!

Works beautifully!!
