TETON Sports Explorer 4000 Internal Frame Backpack; High-Performance Backpack for Backpacking, Hiking, Camping

Paid $75 for the 4000 65 liter green. Went through the rain, trees, thorn bushes and I am yet to damage the pack. I hike every single day, so it's loaded out at 48 lbs 24/7. I pick it up by one strap at least 4 times a day. I haul it out of the SUV and I constantly open and use the contents. Zippers, pockets, pouches and webbing are still working at 100%. I will be using this at sub zero temps soon. I will let you know how it works out.

I just received my pack this week. I've loaded and unloaded the pack a few times trying to tweak my load for a 3 day 63 mile Florida Trail hike from Lake Okeechobee to Hobe Sound (Ocean to Lake Trail). The materials all appear very durable. I thought the stitching in some areas would be reinforced a little better like another pack I own, but it still seems solid and I don't see any potential issues. The zippers are strong, the sleeping bag compartment at the bottom is roomy, and the waist belt and shoulder straps are comfy. The main compartment, side pockets, and pockets in the top rain flap are very functional. The two aluminum stiffeners are sturdy and well placed. The rain cover is completely integrated, rip-stop material, lined for waterproofing, and seems perfectly suitable for a torrential downpour.I have one complaint. My waist is 32 inches, but I have the waist belt cinched tightly. This is kind of concerning. You can lose weight during a long trip and may not have a lot of room for adjustments. If you have less than a 30 inch waist this probably won't work for you. Fortunately, I have a 30"-31" waist when I am working out regularly and doing a lot of cardio, so it should be fine for me. Unfortunately, my recent workouts are limited to carrying a baby throughout the day and heavy reps curling 12oz IPAs:)I'll update my review if I run into any issues after three days of hard use.UPDATE 02/07/2018: The pack held up like a champ. It was extremely comfortable. The waistband and shoulder straps felt great. My only wish is it were a pound lighter, but it’s just fine for me. I can’t justify paying double the price when I don’t have the chance to hike long distances regularly. I’m very glad I bought this pack!

Great for a camping/hiking/survival pack!!!I have had it for about half a year and it has worked great. I hammock camp and this pack has held every thing that I want and more.What I like about it is that it's very comfortable when packed up all the way, it doesn't hurt at all.(I carry a lot)The sleeping bag compartment is perfect, I use my Teton sports leef +20 and it fits great.I would highly recommend this pack.

I love the back "TETON Sports Explorer 4000 Internal Frame Backpack Metallic Silver" I purchased on this item on September 5, 2017. My only complaint would be that one of the side pouch zipper extensions pulls came off. I have not been able to get is back togather adequately. Once when I thought I did I could not get in on the zipper as it was to short to loop upon itself. So after that I tried to reassemble it while it was on the zipper and that did not work either. I wrote teton to let them know of this weakness and within a half hour they replied for a picture for reference and my address. I replied right back with this and within minutes they notified me it was awaiting shipment and a tracking number would be assigned. This kind of response really encourages me to deal with Teton again. Thank you Teton :)

Changing my review from 2-4 stars after using this bag for a bit and putting it to the test. My biggest original complaints were;1 - The top hood doesn't fit over the bag (like it does in the product photo).2 - The inside diameter was a bit tight.3 - The bottom pouch was difficult to access, due to the design of the bag.4 - The straps on top of the bag sit a little far back, making anything that's strapped to the top (if it has weight to it) feel like it's constantly falling off.However, after packing this thing to the brim, plus some added weights (prepping for a big hike coming up and was trying to over compensate for food and such), it held up incredibly.1 - The top actually works as a satisfactory cover, as long as you don't expect it to snugly pull down over a full bag. Since every square inch of this thing is made for storage, I'm filling the pocket in the hood with a ton of stuff and it still does its job.2 - This is something that still might be an issue. I WAS able to get my HUGE sleeping bag in and out of it, but I also upgraded to a smaller mummy bag and it fits significantly better. If you're a big person, that uses a big sleeping bag, especially one designed for colder weather, be prepared to struggle packing everything, even with compression bags.3 - The bottom pouch zipper is significantly easier to use when it's full, so make sure to utilize every square inch of this space.4 - As for the top straps, it's pretty easy to get use to, especially if you're only putting a light sleeping mat up there. I have a pretty light weight tent that I've rolled up and strapped to the top, which can get annoying if you're spinning around a lot and the top hood isn't full, but otherwise it's solid.Overall, this bag has an ENORMOUS amount of space; I have enough extra room to pack my tent as a "just in case" option, for a trip where I'll be sleeping in shelters along the trail. It's also surprisingly comfortable, even with the added 10-15 lbs that I packed into it, I had no problem with weight shifting or this bag throwing me around. The only big drawback being how slim the interior is, but I think that can easily be worked around. 4 stars, because I think this bag doesn't quite knock it out of the park for me, but is definitely super solid.
