Osprey  Katari 7 Hydration Pack - Men's

After using a standard day pack with a hydration bladder while riding gravel and mountain bikes I decided a proper hydration pack was in order. I had the Katari since July and used it on gravel and mtb rides in Colorado while visiting my son, short gravel rides back home and a self supported gravel century this past weekend. It has performed flawlessly. Unlike the hiking day pack this fits snugly and comfortably on my back. I hardly know it is there. The water capacity was just enough for the century. The gear capacity is enough for emergency supplies, food and storing a couple layers. Any bigger and you'd be inclined to pack too much stuff. I've crashed twice on it, the only damage being my ego. I'd recommend it

I have owned this pack for 4 weeks and have used it almost daily for road biking and 2 to 8 hour rides and hikes. I'm in the desert and this pack makes a lot of sense for me. I can pack a light jacket for higher altitudes and still have enough room for extra water bottles and snacks. The fit was easy to dial-in. Unfortunately, the "bite-valve" didn't last even a month. Mine may not meet Osprey standards as initially it was stuck in the open position. This initially did not cause a problem as the valve did not leak or drip. After 3 weeks, the valve suddenly started dripping and the on/off valve started working. At first I thought maybe on/off valve itself was leaking, but I discovered that the leaking and the valve suddenly working was coincidental. As the leak got worse, I could see that I had bitten a hole in the bite mouthpiece. I've owned other water packs for close to 20 years and have never seen this problem. So I'd give the pack a 5 and the bladder a zero. Given positive past experiences with both Osprey and REI, I know they'll make it right and therefore I'm rounding my overall score up to 3.

The pack is light weight even when filled with water. I was on the fence on on purchasing this pack but I'm glad I did! Made going thru a as Spartan race easier. I've been using the pack on mountain bike rides. It's perfect if you want to pack light. Enough room to pack keys, phone, wallet and a small snack. Love the pack and the brand. This is a good quality pack and bladder.

I bought this pack for my fiancé after I got the women’s version 7L and he became jealous lol. We use these multiple times a week on hikes anywhere from 3-10 miles long. They can fit a ton (keys, cellphone, snack, spf and a long sleeve or light weight shell)! The pockets on the side can fit even more if needed. We run with these on too occasionally and they are super comfortable. No more need for our bulkier Osprey hydration packs thanks to this little guy.

Big enough for the essentials on the bike or on a short hike/run. The hydration pack is designed with good ventilation. The waist belt is a simple webbing design with plastic buckle. The sternum strap is also a narrow webbing material. The buckle is an innovative design incorporating a pair of magnets. It clips into two docking holes on its counterpart on the left strap, and the magnets hold it firmly closed. The magnet is also used to hold the drinks tube when not in use. The bladder has a rigid plastic handle near its top to hold when filling it. A tethered rigid plastic closure slide is slid off. A plastic fold-down flap can then be lifted and the reservoir opened. The rucksack has one main compartment with a zip running three-quarters of its length down the centre, with a hook-and-loop fastening cowl at the top to help keep out the rain. Inside are two small mesh pockets with elasticated tops. It’s not cheap, but you do get the Hydraulics LT bladder included. The quality, design and comfort earned this little pack a grough best buy recommendation.

The bag was generally good quality, however the new magnet designs do not hold the hose to the bag. The plastic covering the magnets makes it much weaker than my old Osprey bag. Returned for this reason. Also, ould be nice if the reservoir had the hard backing as a standard. Since the bag is so small, putting anything in it makes it hard to slide the reservoir back in after filling.

This is my first hiking/biking backpack with a water bladder and it just came in today. I haven't used it yet but it feels comfortable and light. The only problem I have with it is that it does not have little strap holders to hold and keep the loose ends of the ropes/strap in place. It's really irritating having it flop around. Also, for the bottom buckle belt, I suggest making it a choice for the consumers in which they can remove it or not because somedays you just want to feel like there's nothing there holding you back. Please add little strap holders to put away the annoying loose strings. Patagonia has it on the chest strap and I think that it was really helpful since it looks more presentable and stable.

Ridiculous. Was CamelBack loyal for 20 years. After viewing every video I could find on this problem, I called Osprey. Ashley told me that they had been having problems with twisting open the valve. I thought there must be a trick to get it to work. Nope. I'm a strong dude. Broke a thumbnail but finally opened it. Very, very bad start to Osprey products. I think I'll like it moving forward.

The nozzle doesn’t taste like chemicals as do Camelback nozzles. It holds tools and a small battery operated air compressor and there’s still room to pack lunch. It’s super comfortable and sturdy and is exactly what I needed for my rides.

Comfortable, lightweight, plenty of storage for a phone, bike tool, etc. A stronger magnet on the chest strap and water tube would be nice.
