Review on SHARKMOUTH Hiking Hydration Backpack with 2.5L BPA Free Water Bladder - Ideal for Long Day Hikes, Day Trips, and Travel by Bret Wong

USEFUL: A few weeks ago I took a road trip to Zion National Park and found that a 2.5 liter tank held more than enough water to fill my 5ft 9in and 135 Pound heavy physique to carry through multiple 5-7 hour hikes in sunny Utah weather. At the end of each day I had about 1 liter of water left and I was already well hydrated before hiking and using a backpack. The right weight distribution has also helped me a lot with my back problems. and made hiking with water much more convenient. I have walked with a couple of water bottles or heavy bottles over my shoulder many times in the past and will not be returning. that the insulated and medium-sized pockets have more than enough room to stash sandwiches and other snacks, my DSLR with lens attached, tightly rolled windbreaker, baseball cap, hat, wallet and sunglasses (all in addition to a full water bladder). As a precaution I kept all my sharp tools in the front pocket to avoid piercing the water bladder, like a knife/utility tool, as well as the rest of the essentials, like a first aid kit, headlamp, compass, fire starter, etc. The front one Chest strap has an emergency whistle built into the buckle, which I didn't notice at first, and it's definitely loud enough to alert someone in an emergency. The shoulder straps are also reversible, allowing you to route the hydration tube through any strap, and the tube clamp can also be moved to either side. I have looked at others here. It has plenty of storage space with 3 zipped compartments and the side pockets are great for an extra water bottle or other items. And if that says anything at all, I think the "Shark Mouth" marking on the packaging and the bladder itself looks pretty good, despite being less well known.
