This is a really great vest. The only thing that struck me is how tight it is for someone who has a bigger chest. Even when loosened it didn't have enough give to fit everyone well and I would like more adjustment and give to customize it for each body type.

This Osprey hydration vest is made well and the same great quality I have come to expect from Osprey. It offers a streamlined minimalist approach to hydration. The hydrating tube is convenient thanks to the magnetic bite valve. This pack is comfortable and will not move around on you when you’re riding. It has a super snug fit, which is a plus and a minus. The S/M is really small. We probably should have gotten the large. It’s always easier to pull the strap tighter. If you wear any layers of when you ride, consider the larger size. It would be great if Osprey would provide a size range for guidance. Additionally, my wife has an iPhone 14 in a slim case, and it barely fits in the front mess pockets. Again, this is a minimalist pack, so consider your needs.

This is a must for any hikers. Very lightweight and easy to carry. The inner pouch is easy to fill and clean.I have this for a few month now and the inner pouch has not yellowed out like some other brands.The pack does run a bit small compared to other brands. I got the S/M size and it is a bit tighter for me. I usually get the Medium size but this runs only S/M and L/XL. I usually avoid anything XL, since it gets way too big, but this was a tight fit.Overall, love this product and would recommend

I got the S/M size, but it really is more of a small. If you're well endowed, consider sizing up. I got the small, and had to adjust it to the largest it could go, just barely fits my chest. Other than that, I really like it. I got this for my longer bike rides so I dont need to stop for water breaks as often and it's such a game changer. It feels nice on, pretty secure. The quality is really good. It's easily to fill and take care of also. It also has 2, kind of small, front zipper pockets for storing stuff, not big enough for a phone. Although, you could probably store stuff in the back with the water pack, it seals really well.The design is really nice. The clasp close by magnets. The hose magnets to the front as well, pretty easy access. It's great.

This is indeed a simple, streamlined, and lightweight task oriented bag, and is on par with any expected high quality bag from Osprey. It fits very securely and won’t bounce around or shift much, and is very suitable for cycling or trail running or even hiking. It sits high on my back right between my shoulder blades and only goes down to just below them. It’s largely mesh and very well ventilated. Tundra green and black is very nice and subtle. It’s good looking.Sizing/harness:There isn’t any shoulder strap length adjustment, but there are adjustments that can be made on the two chest straps and on the sides at the bottom of the shoulder straps to allow for more room. I’m 5-10, 150lbs and the small/medium fits just fine with some room for layers by adjusting the lower straps in conjunction with the chest straps. Females with larger chests may want to consider that when selecting a size - the larger size might be a more versatile choice, thought this is meant to fit tighter by design. The chest strap buckles are magnetic and very reminiscent of a Groove Life belt buckle, which is hands down amazing. Google them if you don’t know what they are - then buy one.Storage:Both shoulders have stretchy zip pockets with large looped zipper pulls, and the right has a stretchy slip in pocket as well. The main compartment has an internal zipped mesh pocket that shares space with the hydration bladder, and an integrated clip to hold water bladder so it can’t pool in the bottom. The diagonal zippered opening makes it very easy to remove and replace the water bladder without a struggle and also naturally routes the hose to right, there there is an opening at the shoulder on the left if you prefer it to that side. The shoulder Strap pockets hold an iPhone 13 Pro in a bulky case and are slightly stretchy so you could also cram a small wallet in with it. There’s a handy loop for glasses between the sternum and lower chest straps on both sides, and an integrated magnetic bite valve holder on the upper chest strap - it’s part of the buckle. There’s also an adjustable bungee on the outside that’s great for any bulky items that don’t fit in the bag.The included 1.5 liter water bladder:Comes with a magnetic clip to attach the bite valve to your chest strap. It does not have an on/off valve closure: though the bite valve isn’t prone to leaking on its own, I sometimes find they will leak when I inadvertently set something on it while it’s in the back of my vehicle. The tube doesn’t include a quick connect / disconnect, through this could easily be added.All in all - very well designed and made, exactly what I expect from Osprey.
