SHARKMOUTH FLYHIKER Hiking Hydration Backpack Pack with 2.5L BPA Free Water Bladder, Lightweight and Comfortable for Short Day Hikes, Day Trips and Trails

This Backpacks job is to carry all of my mountain biking tools and water and it does the job magnificently. The only minor complaint is that the nipple is not good, and does not dispense enough water, so I removed it and replaced it with a Camel Back style nipple that works a lot better on the trail. Overall though, love the design, the smoothness of the zippers, the perfectly sized bladder and opening, and the color (orange). Highly recommend.,

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, its 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 wont bounce loose while hiking or climbing. Ive read reviews about a sloshing problem with the bladder, but thats an easy fix. Once its 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, theres 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 theres 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 didnt 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 theres no way to fix that. Its 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. Ive 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 didnt want to get out of bed to keep hydrated. Its still intact, functions great and can take a beating. Ive 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.

Im a woman, 54, 139 lbs and this backpack fits perfectly. Its super comfortable and has plenty of pockets. I bought it primarily for using while mountain biking and I dont even know I have it on. I have not used it with the water reservoir yet but I did test the pouch and it functions well and has a lock to keep the bottle from opening up on accident. The hose is very sturdy and adequate length. For the price, I dont think you can beat this backpack. Its very well made.

Es mejor de lo que esperaba, tamaño y peso exacto, varios bolsillos para guardar herramientas, me encantó.

The storage was a fair amount and the amount of water it held was good.

Worked great with no leaks and I was able to keep my phone and keys in the back pocket.

Great hydration backpack for hiking. Worked well for use in dry climate. Light weight and comfortable. The zipper pulls had loose strings/threads, but otherwise great for the price.

Love this! Been hiking on day hikes and this works great! Had this for over a year now and nothing has broken and its quality material.

Great little pack for the price. Wish the mouths piece wasn’t pull out and just a bit done kind of deal. But overall seams to be great for what I need dirt biking and day hikes

Bought it for my son. No complaints
