Really excited after receiving this bladder. We plan to order another as well. It's easy to clean and to fill.

Staying hydrated is crucial during any outdoor adventure, and a reliable water reservoir is essential. The Osprey Hydraulics, with its range of sizes (2-3 liters), is a popular choice for hikers, cyclists, and backpackers, and for good reason.What I Found: * Comfortable and Secure: The reservoir fits comfortably within most hydration packs and stays securely in place, even during strenuous activity. The bite valve is easy to reach and provides a consistent flow of water. * Durable Construction: The reservoir is made from durable materials that are BPA-free and easy to clean. The wide-mouth opening makes filling and cleaning a breeze. * Leak-Proof Design: I haven't experienced any leaks during my use, even with the reservoir fully packed and bouncing around in my backpack.Areas for Improvement: * Bite Valve Durability: The bite valve, while functional, can sometimes feel a bit stiff and may not be as durable as some other options. * Cleaning Difficulty: While the wide-mouth opening is helpful, some corners of the reservoir can be difficult to reach for thorough cleaning.Overall:The Osprey Hydraulics is a solid choice for any outdoor enthusiast seeking a reliable hydration solution. Its comfortable fit, durable construction, and leak-proof design make it a dependable companion on the trail. While minor improvements could be made to the bite valve and cleaning process, these minor drawbacks don't significantly diminish its overall value. Osprey is an amazing company with amazing customer service.For this reason, I own a few of their products and will get more in the future.

Bought this to use with an Osprey hiking bag on a pilgrimage to the Himalayas. Convenient and useful. Worth it.

先月、炎天下で開催されたトレイルランニングで使用しました。North Faceのトレランベストに入れましたが、問題なく収まり、チューブも固定でき、飲みやすかったので、走りながらの給水が非常に楽に出来ました。買って一度だけ中を水洗いしただけですが、プラスチックの味みたいなものは、私は大して気になりませんでした。使用後の洗浄は、パーツを一つ一つ、結構細かく外すことが出来るので、使用後直ぐに入念に水洗いすれば、道具は要らないと思います。現時点で洗浄用の道具セットの購入は考えていません。

I was going on a twelve day Philmont hike and wanted to have a good-sized water reservoir. Besides the Osprey brand name, I really liked that this reservoir had a hard plastic backing to it. This allows you to more easily shove the filled reservoir into a fully loaded pack. I had 70L Osprey backpack completely filled with stuff for the trail and would stuff the full reservoir into the pack. It only leaked one time. Initially I assumed there was a hole in the bladder. But I took it out, filled it with water, then tried to make it leak by squeezing it. But nothing came out. My conclusion was that my backpack was laid flat (or slightly inverted) which make the water leak out of the top. After that, I made sure my backpack was either slightly or fully elevated. No more leaks after that. I also liked the reservoir had a slide-off "cap" on the top that was attached to the reservoir with a plastic "string." So you didn't have to ask, "where did the cap go?" That's usually me. Lol. Very good water flow and the ability to "turn off" the water flow at the spout. Came with magnet to attach the hose to the front of your pack. I abused this thing for 12 days on the trail it performed exactly as I had hoped. Recommend it highly for longer treks.

Easy to fill. Lays nicely in pack. Easier to fill when in pack if able, but still can slide in after filling pack. Easy to clean and no odd taste. Strong and durable. Bite valve works great and on off keeps from leaking. No leaks at all and worked perfectly on my 6 day Grand Canyon back country hike. Love it and would buy again if needed. Will recommend to others.

This is an excellent hydration bladder with a perfect bite valve.With other replacements I had to order the bite valves separately since the default ones had a high resistance. Osprey includes a high-flow easy-to-clean valve.The sliding clip fill mechanism was new to me but it works flawlessly.Once closed it will never leak!That is in contrast to various replacement bladders with a round fill cap.These would invariably leak at the most inopportune time.One time while driving to a hike I found the entire reservoir leaked out into my coat!!!Not going to happen with the Osprey.If you are reading reviews to decide then go no further and buy this one.You will be pleased. (I have no relationship with the seller)

I really appreciate the quality of this bladder specially with the stiff back it makes it easier to slide in and out of your backpack. And the quick connect makes this super easy to use. I do wish that the mouth opening was a little wider specially when cleaning, I do recommend picking up there cleaning kit. It is made out of a very flexible material, so i was a little concerned at first but after many trips and having a bear vault pressing up against it for many of my trips I was no longer worried.Tip: if you get down to the very last of your water and you find it hard to drink or there's not enough in your backpack to put some pressure on the bladder, blow air into the mouth peace. This will fill your bladder with air giving you back some water pressure. This works with all bladders.

Osprey çantam için ürünü aldım. Ürün kaliyeli ve güzel görünüyor daha faaliyet esnasında denemedim. Ancak ürünün su içilen emzik kısmının kapağı olsa daha makul ve steril olurdu. Kapağı yok.

I have a number of other bladders including a Camelbak 3L, a generic high quality 2L bladder, a budget 3L bladder. So I have a reasonable range of bladders that I've fitted to a variety of sacks & back packs. I wasn't impressed with the budget bladder so decided to buy a branded bladder. My rucksacks are either Lowe Alpine, who don't do a branded bladder, and Osprey, who do. I own an Osprey Talon 22 (long) so even though its a daysack I suspected it was ok for the larger 3L bladder. I can testify that it fits fine.I picked a 3 litre bladder for the obvious reason that I can have the flexibility to fill it up as much, or as little, as I like. Plus carrying an extra litre of H2O is no hardship. Better to have more than I need than not enough, when I am in need of more, is my motto.The Hydraulics bladder is superbly designed and constructed. Probably over engineered to be honest, but who doesn't like an over-engineered practical bit of kit these days? The slide sealer is new to me but works per4efectly and on relfection is better than the regular camelbak screw cap, which I do find quite hard to unscrew given their propensity to tighten very tightly. The Hydraulics system is way easier and no doubt will be a doddle with gloves or mitts. The hose and mouth piece are superbly designed and the fact that Osprey sell spares is a definite plus point. I also like the sternum strap magnet, which keeps the hose from flopping about.All in all the Hydraulics bladder is a superbly designed bit of kit and though it isn't cheap it is worth buying if you highly value quality and performance.

This is my third one of these. 3L is plenty of water for a longish mtn. bike ride. They keep shape and fit Osprey packs well. The down side is the soft "rubber" part of the mouth piece cuts or tears pretty easily. I thought I was being too aggressive biting down when trying to get a quick gulp while busily trying to make a steep climb etc. but even being careful mine tore after about a year. This results in an annoying drip that ends up on my legs or chest etc. If you shut the valve off it stops the drip but you can't ride with it that way. By the way I keep my reservoirs really clean so i can use them more than a year.

Ich bin sehr begeistert von dem Teil. Sie passt perfekt in meinen Rucksack, die 2 Liter sind absolut ausreichend und die Verarbeitung und Qualität sind einfach top. Was den Geschmack angeht, kann ich nur sagen, dass es natürlich ein bisschen nach Kunststoff schmeckt, aber wie sollte das auch anders sein? Das hat man ja immer wenn man Wasser aus einem Kunststoffbehälter trinkt, aber es ist nicht störend oder eklig! Die Befüllung ist auch super einfach. Das Mundstück ist für mich das absolute Highlight. Es öffnet sich im Mund durch leichtes drücken mit den Zähnen und ansonsten ist es 100% dicht. Der Magnet am Mundstück ist sehr stark und so ist das Fixieren während der Fahrt auch super easy. Also von mir eine absolute Kaufempfehlung auch weil "kaufste billig, kaufste doppelt"Ergänzung nach einem Jahr Nutzung: ALLES immer noch TOP!!!
