Teton Oasis/Trailrunner Hydration Backpack – Lightweight Water Pack with 2L/3L Bladder for Hiking, Running, Cycling, Biking – 2L/18L/22L Sizes – Sewn-in Rain Cover – Fits Men and Women

This bag is great for day hiking. The water bladder has held up excellently despite my jostling it around and often laying back in my bag at campfires. I love the compartment that detaches so you can hook a blanket or a jacket in between and not waste space in your bag. This bag holds true with being water resistant, and I recently took it with me on a kayak and continually dumped water on it and all my contents were dry (and I didn’t even use the rain tarp!). I am 5’7 and it fit me like a glove. My 6 foot sister also tried it on and was able to fit the bag to a comfortable level for herself too. This brand offers cooler color ranges than most, and you can fit nearly everything you could need for a day hike. I cram mine with a full water bladder, blanket, gloves, first aid, a couple beers, speaker, handsaw, and plenty of snacks, and I still have room to spare. The material also does not give any brush burns against your arms if you wear short sleeves or a tank top. I have tested this on a few terrains for hours.The back cushions are comfortable and super breathable - no more swamp back with this bag. I truly wish my own mattress was this comfortable… I honestly might get another of these bags because I love the green and can’t get enough of them!

I received this a few days ago but haven't had a chance to try it out yet on the trail which is why I'm rating it 4-stars at this time.I love the overall capacity of it, as well as all the pockets. I think it will be a perfect bag for day hikes without being too big. I tested the hydration bladder for leaks and there were none. Yes it gives water that "plastic-y" taste initially, but I did clean it with a bit of dish soap, rinsed well, and let it air dry for 2-3 days and that took care of the weird taste. Also there are two outer side pockets that each fit a standard 16-ounce water bottle but they seem like they will fit larger bottles too.The shoulder straps are a perfect fit for me. I was concerned they might be too wide and uncomfortable, or hit in the wrong places based on what a few other reviewers with similar physical dimensions stated. Also the sternum strap and waist strap are adjustable and fit comfortably (for reference I am 5'3, 135, 36C).The medium size pocket in the lower middle section of the bag with the logo on it has three small buckle straps - one at the top of it as well as one on either side (see pics) so it can be unhinged. I wasn't sure what the purpose is but my husband suggested it can be used to hold a jacket or blanket, or anything else along those lines.This backpack looks and feels like very good quality and I can't wait to load it up and take it out on some Fall hikes.UPDATE 10-22-23:This is now officially a 5-Star backpack. I used it for the first time yesterday on a 14-mile hike and it was perfect! It was fully loaded and comfortable for the whole trek.I started out with the hydration pack full - no leaks, and the bite valve worked great. This is my first hydration pack and I sure appreciated the convenience of being able to drink water without having to stop during those times when I was only thirsty but not needing to stop. (now comes the fun part of cleaning the thing lol - but I bought a cleaning kit and some fizzy tablets, so we'll see how that goes!)The backpack held everything I bring on a day hike, though I can see where the bigger 22-liter one wouldn't be bad either for hikes in colder weather when I bring a heavier jacket, a few other light layers, and more food items. I actually might get one in that size too if I can get it at a good sale price.This is definitely a great pack from my experience with it so far, and I'd say get it if you're on the fence.

I've taken this backpack on multiple adventures now. It's taken us across the Grand Canyon twice on a Rim to Rim hike. There's plenty of space for everything I've ever needed for a day hike. It's light and comfortable with adjustable straps. I liked the included hydration bladder, but have since upgraded my bladder just out of personal preference. The included one was fantastic. It was super functional as it has different sized pockets and pockets within pockets. On the last hike, I tethered a solar power bank to the gap between back pockets and ran a wire effortlessly to my GoPro. It didn't have to be in a pocket, which was nice. Highly recommend this pack.

I purchased this backpack to use for day hikes when my running vest is not spacious enough. I have no complaints on the quality of the pack itself. It seems to be well made and has held up to being overstuffed and scuffed around. I can fit my 12.9" iPad Pro in the back section, which makes it convenient for travel as well. The bungies and straps are extremely convenient for locking in jackets, hiking poles, and even water bottles on the outside pockets (essential for steep hikes/climbing.) My only complaint is that the shoulder straps are quite wide, making it uncomfortable to wear if you have a smaller frame. I no longer use it for this reason. The placement of the chest strap is also not ideal for female anatomy. Overall it's a good quality pack for its price; I'd suggest smaller framed women consider a pack designed more specifically for their body type. (I'll be upgrading to an Osprey Daylite).
