Review on SHARKMOUTH Tactical Hydration Pack Backpack 900D with 2L BPA Free Water Bladder - Military Daypack for Running, Hiking, Cycling, Climbing, Hunting & Working Out by John Raj

I'm 5'6" 111 lbs with a short torso. The problem I have with using many hydration packs is that they sit oddly on my body. Either they are too long, or the straps are too wide, because the straps of the backpack sit strangely due to the chest strap. The first thing I did when I opened the package was this suction cup. The pack is wider and shorter than thin and long. I'm obsessed with molle/tactical gear so I was VERY happy when this thing fitted me! The American flag patch is bright, the zippers and material are very high quality. Haven't used a hydration pack yet, but I love that this pack is insulated. It definitely smells like chemical plastic, but usually a little air will fix that. In terms of storage, the pack fits your essentials, the bottom expands to 3 inches, the top does not expand, allowing most of your belongings to fit at the bottom of the pack. There is also an outside pocket at the bottom of the backpack. If you don't want more weight resting on your lower back instead of evenly distributing it, then keep it light :) Bonus: My 13" Surface laptop fits in the main compartment (it didn't fit a hydration bladder), so i even i can use it for my daily commute to work. Yes, I am wearing pajama bottoms.
