SHARKMOUTHHiking Hydration Backpack with Bladder - Insulated Water Backpack with 2.5L Reservoir - Lightweight Hydration Pack for Hiking Running Biking Cycling

I’m not a fan of the logo but the pocket sizes are perfect for light hiking gear all while holding a sufficient amount of water. My main reason for this purchase wa the lack of hip huggers. I find it a little annoying sometimes to have to use hip huggers. I have my other running bag with hip huggers for that type of hiking that requires a bit more support with heavier loads. The material is great and physically tough. The zippers seems a bit chintzy but it actually works great after a few uses and I always wax the zippers of my outdoor gear for a little extra water resistance and the wax make the zipper work so much smoother. The slot for the bladder looks nice with reflective material all around the bladder and a zipper to keep objects from entering the bladder section of the bag. I wrapped a small towel around the bladder to keep it a little cooler. The bottom of the bag leaked water from a small leak when I slightly overfilled the bladder while it was in the bag. Not a big deal if you like ice cold water dripping down your crack! Oh yeah! But the bag isn’t water tight at all. So keep that into consideration when your looking for a water proof bag. The water bladder has a nice handle design that make it easy and comfortable to hold the bladder in a way that allows you to completely fill it. And the bladder fill hole is huge! Handfuls of ice went into the bladder easily! It’s just right in every way it’s intended to be used for. Waterproof would have been nice. I think the price reflects the lack of water resistance. Worth it!

This has been a great purchase! Most of my hiking friends cautioned against getting anything other than the name brand (you know, the one that relates to that humped animal). But this one is well=built, rugged, and water tight. I like that it has a large mouth on the fill opening- that allows me to make gigantic ice cubes in small bowls and put them inside the bladder. The drinking tube is insulated and the bite-piece works well. This didn't come with any instructions on how to best get the bladder in and to run the drink tube through the loop on the arm strap. But once I figured that out, everything has been great. I could've used some guidance on how to best adjsut the straps. Being that I am 6'6" tall, things don't always fit accordingly. But I've adjusted it through trial and error and it works great. There's lots of storage and the water remains cold. 2.5 liters is a great amount for a significant hike.

I’ve put off buying a water pack simply because the prices are outrageous and I could never seem to find one with ample storage under $100. I’ve recently started a bucket list of hiking all the state parks in Texas and a backpack for snacks and water bottles just isn’t cutting it anymore. This pack holds the perfect amount of water with an insulated pouch for it! Not only that, but I have plenty of space for snacks, keys, phone and extra clothing. I would definitely buy this over a Camelbak a million times over

I REALLY wanted to love this product, but it fell short in several important areas.THE GOOD:The pack is nice and feels like it could take a beating, and the zippers are good quality. The pockets are big enough to hold a pocket first-aid kit, snacks and a few more miscellaneous items, making it perfect for day hikes & day trips. The insulated pocket keeps your back from warming up the hydration bladder, and the insulated hose is nice. On top of that, it's a nice looking little bag. I got the "Jungle Green" bag, which is actually dark grey, but I selected the color by picture rather than by description. I love the stormy-grey color with the black.The bladder was easy to fill, insert into the pack and clean. There was no noticeable "taste" on first use, although I did give it a good clean before using it for the first time. The hook on the strap means the hose is well secured and won't bounce loose while hiking or climbing. I've read reviews about a "sloshing" problem with the bladder, but that's an easy fix. Once it's filled, turn it upside-down so the air is by the hose output, suck the air out of the valve until you get water, and THEN place it in your pack. With no air to mix with the water, there's no sloshing sound (this should be standard practice with all hydration bladders.)THE BAD:*edit* Originally I posted a review about there being no height adjustment for the chest straps, which was a huge problem given my frame. As it turns out, what I thought were fixed connection points for the chest straps WERE actually adjustable. Mine were just horribly jammed and it took someone with stronger fingers and more patience than me to adjust the height of the chest strap. Once that was solved, the pack fit much better, and the chest strap was in a more comfortable/usable position. Although very aggravating to adjust, the chest strap height is no longer a problem, and the pack fits well! The waist strap is still fixed, but there's only so much you can expect at this price-point *end edit*I tested the bladder before my first hike and was pleased that there were no leaks. The problems didn't come until I was on the trail. The bite valve has a horrendous leak. When capped and pushed in, everything is fine. But once you pull out the valve, it leaks terribly, and I felt like I was drooling with every sip. I checked to make sure it was firmly inserted to the hose, and it was, and the water output itself was sealed unless I bit or squeezed it. The leak came from between the valve and the hyperboloid-shaped bit of plastic in front of the attachment point, and there's no way to fix that. It's just going to keep leaking, making drinking awkward as hell until I find a new bite valve.Update:I did end up getting a new bite-valve, and now that my fit issues and the bite valve problems are solved, this is a really solid pack. I've used it on multiple day-hikes, a few road trips, an outdoor concert, a couple of day trips and once when I had the flu and didn't want to get out of bed to keep hydrated. It's still intact, functions great and can take a beating. I've updated to four stars, but only because I had to replace the bite-valve immediately after buying it. Had it come with a functioning bite valve, this would have easily been a 5 star review.

Took this out on a 4 day camping trip, and it was great. I was using it at my only source of water, and as my day pack. Even when full of water (a hefty 2.5 litres of it) it still has enough room for the essential survival gear that I'd want to take with me, and a tiny bit of food too. The bladder seems sturdy, and can be strapped to the top of the bag to prevent it from slipping. The insulation seems to have done its job well, as the water from the bladder was consistently cooler than the water in the tube, and the water in the insulated part of the tube was cooler than the uninsulated part. Note that I cut the tube for mine to add in a filter attachment. Normally the entire tube is insulated. The bit piece works well, as does the cover, although I'm worried that the cover will break off in time. If it does I'll update this review. Refilling the bladder isn't terribly easy as you'd have to hold a filter up to it. Some filters can connect directly to it, but most won't. I was able to work around this by filling it via the tube, but for that you'd need a filter set up like I have.

Product as described. Used and water bladde worked well.

I love it because I am constantly practicing for a marathon and I find this Hydration Pack has ample storage room and holds enough water to get me through the day. I highly recommend

Nice backpack. Great for hiking lots of pockets. However if you want to use it for biking it's a little heavy and bulky on the back.

pratique,beaucoup de rangement, peux marcher les poche vide et avoir de l'hydratation à souhait
