Really great backpack!

  • Familiarity:I gave it as a gift but have feedback to share

I love this backpack! I love the fact that is has a lot of adjustable straps to tighten or loosen. The ones for the shoulders were really useful because most packs lack those straps and having it made the backpack fit better on me. I’m 5’1” and the backpack fits really well. The top pouch is handy, really nice to put small things like my keys or phone there. Overall, a great day pack for my hikes with my dog.

Hands down most versatile pack I've used

  • Familiarity:I've used it several times

First I was looking for a bag that I could use as my daily bag for running shoes and discs and snacks and drinks and layers etc... I also wanted that pack to be my technical pack as well. Hence the Ultra Kompressor. After exhaustive research and wanting the most bang for my buck I settled on this exact little beauty. I bought the black model.

I've had it about a month and a half. It's my daily carry. I'd be lost without it at this point. It carries exactly what I need and is very asthetic and streamlined not seeming bulky at all. This pack always finds a way. It's incredible. When I need just a little more space it has it. It duals as my diaper bag as well which looks much more hardcore than my florql design actual diaper bag. Fits all mine and my sons stuff for zoo trips and jogs.

Then the weekend rolls around and its time to hit the trails. This bag converts flawlessly. It's slightly more robust shoulder straps have no trouble handling a 15-20lb load. The shoulder load stabilizer straps make all the difference in the world, conforming the pack for your back for the most stable possible carry. The removeabe waist belt stops the side to side sway combined with the perfect sized sternum strap turn this pack into an extension of your body.

Every review mentions if you're a minimalist you might be able to use this pack for an overnighter. This is seriously underclassing this pack as a daypack. I hardly consider myself minimalist and this pack handles everything I need perfectly. Marmot summer synthetic bag, grand trunk skeeter beeter, warbonnet superfly, imusa pot with titanium mug and plastic pudding tub inside, extra shorts and shirt, down hoodie, an entire extra bugnet for my buddy, a few mountain house meals, some trailmix, coffee, muffin mix and some tuna and noodle packets........ ::inhale::.... My wallet, phone, charging stick, socks, sandals, BUG SPRAY, tent stakes, headlamp, biofreeze stick(like bengay), collapsible half liter canteen and 1 quart of water. All of that inside this "daypack".

I've had it out 2 weekends so far and its been incredible. My shoulders and back haven't been strained or ached at all. It carried the load flawlessly. Well, well thought out pack. I just keep thinking bang for your buck with this pack. Oh, to boot even the laptop sleeve pad came in useful to sit around the fire when I didn't feel like sitting in the dirt or retiring back to the hammock. This pack always comes through.

If you want a one pack option for school, diaper bag, gym bag yet be technical enough to tackle rugged terrain or climb, you will not find a better pack, especially not at this value. It's a no brainer if you're even considering buying it, buy it.

I bought this pack myself and no one paid or asked me to write this review. I just love this pack this much and there isn't a ton of practical in use information on this pack. I hope this helps.

Hands down most versatile pack I've used

I just bought this and I cannot see any way to remove the closed-cell back sheet -- there is no opening or slot to pull it out. Is this really removable or is that a typo/missing feature?

So usually its found inside the pack and not on the outside, not sure where you are looking. Sometimes it can be very tricky. Once Marmot opens up, Ill give them a call and find out for you.

You can call or email me directly. 801-736-6398, or


You have the latest model; the sheet is not removeable. I continue to contend that this product is falsely marketed as a compression sack; it most definitely is not, especially compared to earlier years' models that had removeable foam and much longer straps for real compression of clothes and/or a sleeping bag. This is a good daypack regardless.
