Incredible views and remote trails are just some of the rewards you’ll enjoy when you’re backpacking in the wilderness. The best backpack makes all the difference. And because backpacking can push you to your limits, you need gear that can keep up with you and your latest adventure.

- LLarryVerified ReviewerI recommend this productRated 5 out of 5 starsMar 16, 2023Excellent first internal frame backpack for me
My review of the Explorer 4000 (probably called the Explorer 65 now) is consistent with most of the other reviews. I love this pack. It has many nice size pockets and attachment points. It is very well thought out. It's been many years since I purchased this pack and it has served me very well. I'm over 70 years old now and it's going with me this Fall to do some more solo backpacking in Utah and this bag gives me great confidence that I can do it comfortably. Thanks TETON Sports!
- FFFrank F.Verified ReviewerI recommend this productRated 5 out of 5 starsNov 26, 2022Great value, highly recommend
I bought one via Amazon. The first time we used it, one of the straps that allow you to adjust the sizing tore. Probably a manufacturing defect. I emailed Teton and the customer service was excellent and polite. They replaced the pack and told me to donate the other one. I spent almost twice as much on a major sporting goods brand pack of the same size. I think the Teton bag is a better value. Our family is into shorter trips, not ultralight junkies. This is perfect for us. I’ve looked around, and I can’t find better products for the money anywhere. Unless you’re willing to risk the weirdly-named companies selling on Amazon (and I’m not), I can’t imagine doing better. Plus Teton seems to have fairly frequent sales. So why risk it? I’m sold on Teton. Unless and until I step into ultralight territory, or venture into some extreme need, this is my go-to backpacking company.
- KMKimberly M.Verified BuyerI do not recommend this productRated 1 out of 5 starsApr 30, 2023Cheap but uncomfortable
Bought this pack for a camping trip a week ago and it is the most uncomfortable pack I have ever owned. The price point was good but my back was hurting within a few minutes of setting out. No matter how many times I adjusted it I couldn't get it to sit correctly.TETON SportsMay 4, 2023
Hi, Kimberly. We're sorry to hear that the Explorer 4000 didn't fit quite right and understand it doesn't work for everyone. We don't currently have women's specific backpacks, though it's something that we are actively working towards. We'd be happy to take a look at how it's being adjusted and packed to see if we can recommend anything that may help! Feel free to reply to our email from firstname.lastname@example.org so that we can chat more about this.

Not hard to use but kinda weird shaped back pack. I was hoping for a bigger main pack
in the way of putting all the need camping gear inside it. My USGI assault pack carries more.

Great value, well engineered and has everything you need for a great overnight camping experience.
- PRPatrick R.Verified BuyerI recommend this productRated 4 out of 5 starsFeb 2, 2023Can't beat the value for the money
For the money you can't beat this backpack, you can spend more money and get better but why bother, this is a good quality backpack that is designed well.
- RARon A.Verified BuyerI recommend this productRated 5 out of 5 starsJan 13, 2023New favorite
I have a number or packs and this is my new favorite. The adjustment of shoulder straps and the way you can raise or lower the load on your back is something I wish I had years ago. This pack is a bit heavy because of the fame but well worth it. Very nice pocket lay out and not too many zippers to go bad. Nice !
- GHGlenda H.Verified BuyerI recommend this productRated 5 out of 5 starsDec 16, 2022Quality backpack.

- EHElena H.Verified BuyerI recommend this productRated 5 out of 5 starsOct 4, 2022Amazing well designed bag!
Fantastic pack, was shocked at how much stuff I could get inside and with the additional pockets, I had room to spare. There are so many features and functions it was easy to find a great space for every item. It rained on our last day and the rain over worked perfectly!
