    I love this bag for hiking! Even just for a day out at a theme park or something! Perfect amount of storage!

  • Lindsay

    I’ve used this paxk on nearly every hike for a couple of years now and could not possibly love it more. Holds adequate water for any day hike, and with plenty of storage for other hiking essentials. I even load my camera and tripod most of the time. Bought one for my dad and my brother as well and we all love them!

  • Mark Pounders

    I have always been a fan of companies who stand behind their products with a great warranty and Teton Sports is no exception to that rule. They have a great line of products and (more importantly) they stand behind their products with great service. I have the Oasis 1100 and after about a year of use it developed a slight malfunction. I contacted Teton and was immediately answered by their rep, Alexandra. She was prompt, courteous and helpful with some advice on what could be done to resolve the issue. If you have always been a fan of companies like LL Bean, Osprey, REI and Orvis, you should definitely add Teton to that list. Their pricepoint, warranty, customer service and product quality should definitely put them at the top of anyone’s list. Thanks Teton and Alexandra!

    This is my first pack that I will use to go explorin, it’s made extremely well, I can honestly compare this pack to many Camelbak packs really great job the attention to detail I think sets Teton apart I love my Oasis 1100 again Teton you have another lifelong consumer ??

    6 months in I really enjoy this daypack. Size is about right for 99% of my day hikes 5 mile to 30 miles. I did remove the Hydro bag as I prefer 1 Liter smart water bottle and filter to refill. Rain jacket/down jacket, socks, solid lunch works well for how I use it.
    100% suggest this pack for anyone getting into non overnighters. 6 stars if I had the option.

  • KaiLee

    This backpack is the perfect size. There is enough room for all the essentials while hiking or going on family outings, but it’s not super heavy. It also includes a 2L bladder which is super handy and easy to use. My mother-in-law tried it out when she was visiting from out of state and she liked how comfortable and adjustable it was. The bungee storage in the front is nice for storing a jacket or hat, (or the stuffed animal you told your kids not to bring that you will inevitably end up carrying). I also really like that it comes with a warranty. Too bad the warranty can’t help with my mother in law stealing it! Would definitely recommend. I love the bright blue color!

  • Dennis Barron

    Great product, even better customer service. Will definitely recommend.

  • Sarah

    Such a great pack! Carries your water and has enough room for a jacket or some trail snacks. Perfect for day hikes! I love how the hydration bladder tube can be secured over your shoulder so it stays up away from dirt and dust and is right there when you need it. Makes it super convenient and very easy to use.

  • Julie

    This is THE backpack to take as your personal item when traveling, no matter where you go. It is my “Flat Stanley” and has been to Hawaii, Alaska, Florida, Boston, New York, California, Arizona, Bahamas, Utah, Idaho and probably others as well. It has just the right amount of space for carrying those essentials that you need on a trip, including a pocket that can hold a hydration bladder or a small laptop. The front pockets are perfect for separating those small things that I need for quick access: tissue, chapstick, sunscreen, snacks, sunglasses, phone, etc. The straps allow me to tighten or loosen depending on the fit that I want. When I’m planning on a hike or a trip, this is the pack I reach for. I love my Oasis1100!

    I’ve owned an Oasis 1100 for 5 years….tough & practical this is my go-to pack whether hiking or cycling! It’s versatile and lite with compartments to hold most things you’ll need for day hikes or a quick 20 miles on your favorite bike trail! As a NPS seasonal ranger I preferred my Oasis over the standard-issue pack since hydration on the job was of prime importance. Quality and dependability you count on every time!
