    Very lightweight!

    • Familiarity: I've put it through the wringer

    i love the compression straps on this bag! very functional and no unnecessary additions that get in the way. An overall awesome backpack for dashikis or anything else!


    • Familiarity: I've used it once or twice and have initial impressions

    I love the size and how light weight it is. I purchased this for a trip to Mexico to hold our goods while we on day adventures and I can already tell its going to pass with flying colors! my favorite thing about this pack so far is how it folds completely flat so it takes virtually 0 space in my carry on!

    Super Versitile

    • Familiarity: I've put it through the wringer

    I received this as a gift and didn't think i'd use it much at first but i was wrong. It super versatile and goes with me skiing, biking, hiking and most recently brought it to Anaheim stadium to carry a jacket for the evening show. Perfect size and super convenient with the zipper pouch on top for your phone and wallet.

    More than just a bag

    • Familiarity: I've used it several times

    I was looking for the perfect day hike backpack since my Camelbak only has one small compartment. I had my 2L hydration bladder, a jacket, vest, scarf, gloves, headlamp, and snacks in there and still had room to spare. I’m a sucker for smart gear that packs into itself and also like that you can compress so the items don’t wiggle around. The whistle on the sternum strap is a nice safety feature. It’s super light and the straps are comfortable so it checked all my boxes. The negatives: It isn’t waterproof but I will spray it myself. I wish there was a side pocket so you can put your phone, bear spray or anything else you need to grab quickly. I was recently on an icy, snow hike and there were some falls though, so maybe it’s best everything is contained. :) I also took the foam insert out because I don’t like how it shapes the bag. Ultimately I’m very happy w the purchase. I stayed neutral w black so I can use for urban adventures too.

    Just what we needed

    • Familiarity: I've used it once or twice and have initial impressions

    My husband and I took this lightweight, packable backpack to Europe with us. It was easy to store in our luggage and take out for use during the day as we walked around to see the sites. It's the perfect travel pack because, since we got the black, it wasn't flashy and the chest strap ensured no one could rip it off our backs in the touristy areas. I can see us using it as a day pack for hikes in our near future.

    Another Top Notch Marmot Product

    • Familiarity: I've put it through the wringer

    Marmot makes nothing but great gear in my opinion, and this Kompressor bag reflects just that. There are so many ways that you can use it, and the hydration sleeve makes it even more universal. I've used it for everything from snowboarding to biking, and it even works out awesome for just an everyday bag. I toss my 3L Hydration bladder it in and i'm set for the day's adventure. It's the perfect size and such a great little 18L pack!

    Multi Purpose Bag

    • Familiarity: I've put it through the wringer

    I initially bought this bag to use on a NOLS course in Absaroka Mountains in Wyoming. I packed my sleeping bag in this bag and would pack it into my larger pack. The compression straps are good enough to make your sleeping bag manageable while also being able to be used as a day bag if you decide to stay in the same spot for the day.

    I used this bag on countless trips since including a 3 month adventure with the forest service and day trips all over the country. It lasted me a total of 10 years before I finally had to get rid of it! If you are looking for a small bag that can equip quite a few of your needs this a great bag to add to the quiver.

    Multi Purpose Bag

    too flimsy

    • Familiarity: I returned this product before using it

    I don't really like to be a harsh reviewer but I was expecting way more from this bag. It is like a sewn nylon bag that has no structure and doesn't distribute weight evenly. The thing I disliked the most was the back, there is no padded back and the only thing that is like a pad is the water bladder separator that is by the way removable. Once you remove that pad the bag becomes even worse. I am really disappointed, it looks and sounds like a great bag (light and nice design), but the flaws overcome that. I am returning this right away.

    I believe you purchased the wrong type of product: " has no structure and doesn't distribute weight evenly. The thing I disliked the most was the back, there is no padded back ". Generally speaking, a backpack that weighs in at 11 ounces will not have the kind of support needed to carry anything more than 10 lbs. Additionally you would probably need to load balance the items to make the most of it. You need something a little bit heavier, maybe a 1 pounder backpack with more support and additional adjustment items.

    Light as a feather

    • Familiarity: I've used it once or twice and have initial impressions

    An ideal pack for day hikes. It's super light and comfortable on the shoulders. It has a comfort cut shoulder strap design that are nice and wide. The material is also super breathable so you won't be sweating under thick fabrics in the summer. Fits everything you need for a day hike, and is super durable on the mountain. Cleans easily. Honestly this is the best your money can buy for a simple, well designed hiking backpack. GET IT.

    Super versatile and light

    • Familiarity: I've used it several times

    This thing is great for short day hikes. Super lightweight, stuffs into its own top pocket. I use it hiking, and when I'm not hiking I put my climbing gear in it to bring with me to the gym. I haven't worn it for multiple days, although I think that would start to rub on the shoulders as they are really thin.

    Perfect size

    • Familiarity: I've used it several times

    I was looking for a pack that would be great for an afternoon hike without being too heavy or too bulky. This is so so light and fits just enough for a few hours on the go. Folds down if I'm not using it's extra space. The quality is killer too. Awesome buy.

    Ready, set, go!

      This lil' bugger is the bomb when you need a super light summit pack to stash away on multi-day backpacking trips or as a just-in-case item to bring with you when you're traveling and stumble upon a cool hike. I only wish it had a waist strap--oh well!

      Low Key, High Ratings

      • Familiarity: I've used it several times

      I've been using this pack for day trips, school, and general shenanigans for a while now. It is very easy to stow away, but works very will when filled with stuff! Perfect pack for anyone who isn't looking for a bulky, sweaty pack with back support. I look forward to trying one of the larger sizes.

      Sweet pack!

        My favorite day pack. Just enough for what you need and nothing else. Folds into itself and you don't even know it's there. Unfolded it's still small enough to use as an efficient hydration pack. Great all around bag, I carry mine every day

        Great Light weight pack

          I received this as a gift and I really that its light weight and very stowable. This would make a nice addition for a backpacking trip or traveling in which you wanted to pack a small day pack without having to carry it separately. It does have a rigid back and nice shoulder straps making it much nice then a drawstring bag

          1) very lightweight
          2) stowable
          3) 3 cinch down points for the brain
          4) many contact points to clip carabiners
          5) Zipper brain pocket

          1) pretty flimsy (not too great for running)
          2)No waist strap (only chest)

          Ski/Hike/Travel Backpack

          • Familiarity: I've used it several times

          I got this backpack to take with me skiing. It is extremely light weight and doesn't weigh me down at all. The drawstring is easy and practical and I really like the daisy chain strap for tying my snowboots to the back. Straps are adjustable, secure and comfortable. Stuffs into itself to form a neat little pillow too! All around a great, versatile backpack to have!

          BEST PACK EVER!

          • Familiarity: I've put it through the wringer

          I love this pack! So light weight and packs down small if you are traveling. This pack is great for hiking or great for traveling. I love that it has a sleeve for hydration bladder. The pack also cinches shut. Love it!

          Light and comfortable

          • Familiarity: I've used it several times

          I've taken this out a few times now, and I am definitely liking the weight and the comfort of this pack. It easily holds all I need for a day hiking. I would love it even more if it had at least one exterior pocket but I can definitely live without it.

          Light and comfortable

          Great daypack!

          • Familiarity: I've used it several times

          The lightweight pack worked great for sunshine and in the rain, only for a short amount of time. It's comfortable with it lightly packed and packed to the brim. A friend and I took turns carrying it and she was completely impressed by the comfort and ease of use that's she's planning on purchasing one as well.
