Perfect for Bike Rides â Love the Rain Cover Feature!
This Everfun Hydration Backpack has been a fantastic addition to my biking gear! The rain cover is an absolute game-changer, especially when I get caught in unexpected weatherâit keeps everything inside completely dry! I honestly didn’t expect that to work so well, and there’s a built in compartment to store the rain keeper so you don’t lose it.The 18L storage capacity is impressive, with plenty of pockets to organize my essentials. I love the thoughtful design, like the velvet-lined pocket for my phones and sunglasses and the side mesh pockets for trekking poles or snacks. The insulated bladder compartment is another great featureâit keeps my water cool for hours during a long ride, which was a lifesaver – I live in a hot climate so I can’t stress this enough.The 3-liter bladder is easy to refill and clean, and the high-flow bite valve works perfectly. The built-in helmet space and reflective strips are thoughtful touches that add to the packâs practicality and safety.Overall, this lightweight and comfortable hydration backpack has exceeded my expectations. It’s perfect for biking and would work well for hiking or running, too. Highly recommend for anyone who loves outdoor adventures! Very satisfied with this purchase.

Perfect for long hikes
Bought this for our hiking trip and worked great for me! Itâs not too small but not too big and bulky at all. The water pack worked really well too and didnât leak at all. We hiked for 5 hours and it never felt uncomfortable. I was able to pack several snacks, a couple of extra articles of clothing and even an extra water bottle on the outside pocket. Highly recommend to anyone who is looking for a quality hiking backpack without spending a fortune.

Great quality, spacious, useful daypack
Excellent quality. Durable. Pockets are spacious, convenient, but not excessive. Bladder works great and is relatively easy to clean and refill. All features are intuitive (pockets, hooks, etc. where I’d put them) and not clunky. Love this pack

Small backpack with nice features!
I was looking for a smaller backpack for daytrips. I have a 40L Ecogear Snow Leopard pack that I LOVE but the company is no longer in business. So far I like this pack for the following reasons: 1) lightweight, but roomy. The main compartment is tall enough to hold my knee pad that I carry to yoga class. I can easily stuff my rain jacket and a down jacket or vest inside at the same time. 2) Built-in rain cover – one of the reasons I picked this bag over others of similar size: the rain cover is essential on multi-day hikes/walks to keep your gear dry. 3) 2L bladder – works well and it’s nice to have the option of either shoulder to run the hose out of. 4) Comfortable shoulder straps – at first I thought this pack was too big for me (5′-1″ tall) but I actually like having the shoulder straps away from my armpits – this means no chafing for long hikes and plenty of room to move my arms (I use trekking poles).Cons: Although you can use a bladder, sometimes you just need a water bottle! The side pouches are very small and it’s difficult to fit wider bottles into them, but since there are no loops to hang trekking poles, I can see using the mesh pouches to hold the poles and running them through the outer straps. It also would be nice if every zipper was set up with two zippers – only the main pouch is set up this way. The hip strap is adequate, as the pack is small, but I would have liked a padded hip strap.Separately, I use a Boosteady camera bag that I attach to the sternum or hip strap to keep my phone handy for taking photos along the way.So far I have used the backpack for getting around the city; looking forward to trying it out on longer day hikes and taking it to Japan this coming October for a 7-day walk in Tohoku.

Backpack great / Water bladder better
I love the color of this backpack and the many pockets. The water bladder design and straw are just awful. It’s difficult to fill if you don’t hold it just right because it doesn’t open up to allow the water to flow into the bladder. You have to hold it open. It’s difficult to get inside to wash it properly because the hole is too small. When I leave it on a rack to dry, I often come back, even days later and realize that water has accumulated on the bottom (top), meaning after I empty it again, it requires a good three more days to dry. The straw has had drops of water in it for almost a week, even after disconnecting the mouthpiece. Speaking of that, it’s very difficult to get enough water per sip. It doesn’t open enough. On my way back on my last hike, I couldn’t get any water out, it felt blocked but I thought it might be empty. It was more than half full. I’m not sure what happened. Spend a little more money and get a good bladder.UPDATE: The day after I wrote this review, the seller wrote me a very nice note and offered to send me a newer version of the bladder that came with the pack. I was blown away by how kind they were and how honest and prompt. They said I would receive my new bladder by the 6th and I did. I have not tried the new bladder yet but the opening to fill it is larger and there is a cover over the straw so you can protect the part that goes in your mouth. They also suggested that I dry out the inside with a paper towel. I couldn’t easily do that before since the opening was so small but I think I can now. Thank you!

Great back pack. Seems to be very good quality.. perfect size for biking.. can fit aprox. 6 500ml water bottles or a sweater but not big enough for both.. maybe 2 drinks and a sweater will fit.. bladder set up works well!

I found this hydration back both comfortable to wear, even when fully loaded and weighed down with the 3L Bladder inserted. Does someone keep the back cool while riding (At least I didn’t really get sweaty from wearing it) and plenty of pockets to put my stuff in However, when you’re missing half your teeth having to bite down after pulling open the part that goes into your mouth to drink water from it is a bit challenging.. I just wished they had put on a twist to open end on instead.. Would have made it easier for people like me who’s missing all their bottom teeth. But a quick fix was to simply remove the plastic sleve thats covering the outside of the mouth piece.. Either way, I’m impressed with it.. Oh, and the material is extremely durable and tear resistant !

Bonne qualité, beau sac. 2 pochettes mais qui ne se détachent pas, seul inconvénient.

The bag have a lot of space and the water stay cool in there because of the pocket inside. I recommend the bag.
