I bought the Teton Oasis day pack as a light pack for a variety of limited or impromptu outings. I also own a Teton Talus 30L pack which I use for full day or two of hiking trips. The Talus offers some features I like and rely on regularly, which Is why I considered the Oasis .The Oasis now is my answer to a limited quick grab and go, always loaded and by the door pack. It is lightweight, can pack down easily into a suitcase, pannier or duffel for transport, is well made and has adequate capacity to store what I would need for a nice day. There is ample opportunity to easily stuff or retrieve a rolled up rain jacket or fleece without going inside. The Oasis is comfortable for hours of wear, is utilitarian with opportunities to attach stuff on the exterior of the pack. My fav. The 3L water bladder is a nice feature too, but I will probably rarely need to carry that much water on an outing where I take such a small pack. Nice idea, but I would probably drop in a 1.5 or 2 liter bladder, or slip a Nalgene bottle in one of the side pockets. If I’m heading out where I need to carry 3 liters of fluids I would be bringing a larger, more rigid pack and likely more stuff too. I would not consider using the 22L Oasis pack for an overnight as I would the Talus. Overall, the Teton Oasis pack is a small but convenient size, is well thought out and constructed, and fun to wear. I wish it had daisy loops, but I can’t ding it for not having them. The Oasis will probably be my last day pack, unless t gets stolen by an envious passerby. Then I would buy it again.

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 absolutely love this bag. This is my third one and not because they are poorly made, but because my kids love it and wanted one for themselves. My only complaint is the opening of the bladder and the clip that goes across eventually stopped working on my first bag which is an older model. I did have to buy another bladder at a sporting goods store that has a twist opening which is easier to open and close. Overall this bag has ample space and a spot for almost anything you can think of. It does well for day hikes. I've used it as a purse when on vacation as it holds quiet a bit even with a full bladder. I also like on this updated model that the bladder has its own separat section and you can pull it out without having to open the main pocket. In terms of price, I think it's definitely on the cheaper end compared to other hiking bags and is great for people who want something sturdy but inexpensive.

My only complaint is that the main compartment's zipper is hard to open & close because the flap over it is so stiff. Otherwise, it's holding up well and seems to be a great pack for fit and quality.
