Why We Like The Mountain Hardwear Camp 4 45L Duffel Bag

Mountain Hardwear's Camp 4 45L Duffel Bag is the perfect size for a quick weekend getaway. The durable 420D nylon holds up during all of our adventures and the water-resistant coating encourages water to bead off so our gear stays dry and protected. An external zippered pocket can hold shoes and dirty gear. That same pocket can also be reversed to store the duffel when not in use. Removable foam-padded backpack straps make this bag comfortable enough to carry through train stations and airports.

great duffel

Great duffel for weekend/carry-on use. I'm a fan of simple and functional, and this checks the boxes. Easy to carry by shoulder strap or backpack straps. Single outside zip pocket and inner elastic divider provide just enough organization. Fully loaded it's still carry-on size. Well-built, looks good, very happy with it. It does seem a little strange that the shoulder strap can un-buckle on one side but is sewn in on the other side rather than being removable like straps on the larger bags, but it doesn't bother me at all. In short carrying with backpack straps I don't notice the shoulder strap being annoying at all.

Great travel duffel / pack

Perfect bag for a multi-day international trip. I purchased this specifically because mutiple reviews mentioned it fits in overhead compartments, and it did not disappoint. The backpack straps can be quickly removed and stowed into a side pocket to be out of the way when not in use. I just used this as my go to bag for a 5 day multi-country trip and was very pleased with it.

It ain’t bad fellas

It’s pretty good I’d say. Honestly it’s a little too much tech if we’re being honest. However I do like the synched bag inside the duffel itself. And I know this sounds stupid. But it’s seems a little small to be a 45 liter

Excellent bag

Awesome bag. Amazing how much will fit in a 45 liter bag. Very versatile. I do wish it had a handle option to carry like a gym bag instead of the single shoulder strap. Great bag though. Super durable.

Probably the best value in this size/price range

Having designed bags for years, I understand some of the compromises made with this duffel regarding the strap system in order to hit the price point & maintain margin. That said, it worked great on a weeklong trip to France & fit easily in overhead bins. No complaints on capacity or durability.

Packable bag

Great bag. Fits in the overhead. Good weekender. I bought this for my wife for Christmas. We have some quick trips coming up. Making use of the overhead is great.

Good Bag - Good Style

The bag looks good, and is built fairly tough. The Zipper is VERY Stout. It works well as a carry-on and is a little under the common size requirements. The should straps are not padded enough and reduce circulation while standing in line or on cross-terminal trips. I have very broad shoulders, so it could be a personal fit issue. I wanted the waterproof material to be a little more like drybag material. Instead, it appears to be ripstop with a waterproof coating. But, that is just my personal preference. It sheds water well and has already survived a hunting trip to Argentina.

super comfortable and convenient bag

This is the best travel bag I’ve ever had. I brought this for a 2 week backpacking trip through Europe. I went through London, Amsterdam, most of Switzerland, 3 major cities in Italy, and Croatia. Needless to say, it was FAST PACED. This bag was fantastic. I was skeptical about how the zipper was down the middle, therefore would be on your back but it was not an issue at all. I was also skeptical about getting a bag that didn’t have hip straps but I wasn’t hiking I was just walking about 20-30k steps a day through urban areas. but at the end of the day I liked how it didnt have hip straps because it allowed for a more casual look. my only complaint is that duffle strap that goes the length of the bag is kind of awkward because theres no way to store it when you dont have it clipped in. so that definitely needs to be redesigned in my opinion.

Great Bag

Excellent bag. Much roomier than the 45liters would seem. Took it on a 3 day climbing trip and I was able to load more things than I could use for that amount of time. Love the side pocket with separate compartment for wet stuff. Zippers, an issue I always had with Patagonia bags, worked very well. I liked this bag so much that I ordered the 65liter also.
