Mountain Hardwear's Camp 4 21 Women's Backpack was designed to take you on sunrise hikes and get you to your early morning classes on time. With a women-specific support system, this pack is durable enough to hold up on rocky scrambles and secure enough to carry your laptop. The laptop compartment fits laptops up to 15" and serves double-duty on hikes (it has a universal buckle for hydration compatibility).

Incredible bag for the price.

I had this lightweight backpack for a year. I bought the larger size first, several years ago, it's a great bag but bulky for EDC. They both remain to be my most used bags. The 21L fits: -small peak design packing cube filled full with gym clothes -north face dopp kit 3.5L -running shoes size w8.5 -mirrorless camera with an extra lens. -14in macbook pro -Sunglasses, keys wallet & earpods. It remains to be still comfortable. And easy to maneuver on a plane or subway. The clam shell opening is essential for easy access in crowded environments and quick organized packing. cons: -not waterproof -no separate opening for laptop quick access -laptop compartment takes a bit of work to put laptop in -could use a quick grab pocket on the front -no pocket on shoulder strap

Great, versatile backpack! I mainly use it for travel. I like that it has one big compartment with smaller pockets.

Ideal Backpack

I really like this backpack! It has a sensible flat bottom, some light-colored lining in the interior which helps with locating items at the bottom. There are two handy handles on the top. It zips all the way down on one side for ease of access. I like that it has one bottle pocket. The material on the front of the bag is water resistant which is especially nice. Overall, it's perfect bag for travel with a laptop or an overnight stay.

Great backpack

Nice sturdy bag that has a squared bottom so easily sits on top of luggage plus the two handles on top are nice to easily grab. The bag has good space and pockets. So far it’s been great.

Nice backpack

I got this to replace a north face backpack that had ripped and I definitely like this one! I do have to say the inside of my old one felt a little roomier and had more organizational pockets BUT this one feels like good quality and it stands up on its own which was really helpful. Also I was a little worried about pockets but it has one on the inside, a long laptop pocket, and another zippered pocket on the outside by like your neck which is super helpful! Overall I would say it works great

Exceeds Expectations

I've used it several times

This pack exceeds every expectation. Not only is it the perfect size for my 5 ft body, but it didn't leak a bit in the pouring rain. I've used it daily for about a month -- hope the waterproof factor continues.

Very handy pack, but not for a large laptop!

I have had this pack for over a year and it works out great for me as both a day hiking pack or for going to the office. Just one clarification for folks looking at this pack for carrying a laptop. I have the smaller 21 women's version. If just fits my 14" slim laptop with no problem. There is no way you would fit anything bigger. Perhaps the pack in the 28 size would work for that, but not the smaller one. Just hoping this helps people decide on the correct size.

Good bag

It's a nice bag, could use another exterior zip but even without its solid. A little bigger than I was actually preparing for but works well for multi pitch days. More interior clips would be nice too. A softer bottom by the back would be nice because it does sit oddly at times and kind of dig in to my back, especially if only wearing crop tops.

Great backpack

I've used it several times

I love this backpack. It is very versatile and looks like it will last for many years. It has a lot of pockets making organizing easy. The exterior top pocket for keys, glasses, phone and other items you want handy is awesome. It is great that this pocket it on the top back of the pack. It protects everything in it better than if it was on the front. I love the big loops at the top of the pack. They allow you to grab and carry it easily. I love the ease of access the full zippers provide and the big adjustable water bottle sleeve. I use this as my bouldering pack to carry food, water, clothes, climbing shoes, chalk, etc. The only negatives for my specific use is the interior laptop sleeve as I never use this pack for carrying a laptop, however I use this sleeve to store my guide book or other items I want to protect. A second small water bottle sleeve or exterior pocket for trash would be nice. One negative is when I carry it on my front with a bouldering pad on my back, it is a little tall and hits my chin. (I'm 5'3" so I doubt this is an issue for many people.) Finally, I would love if it came with thin bungee cord on the front of the pack to allow for easier storing of extra layers or other items. I plan to buy some cord, but it would be nice if the pack already had this. This is a great pack and I highly recommend it. I would immediately buy it again if needed.
