Like the REI Flash 18 better

  • Gender: Female
  • Familiarity: I've used it several times

I thought this bag would be superior to the also 18L REI Flash which only has one inside pocket while this one has pockets on the outside which is nice, but NO INSIDE POCKET... not having any compartment on the inside kinda sucks...
But, the shape of the bag is such that it's shapeless and awkward when it doesn't have much in it. This bag is a little wider and shorter than the Flash but while the Flash closes with a draw cord and no cover, this one has a lid with a pocket which is pretty nice. It also has cords for attaching stocks/ice tools while the Flash only has one loop.
I miss the hip belt as this one lacks one, the Flash has it, I didn't feel the pack moving so much while I ran, with this bag it's definitely shifting left and right while I run. Others say it's comfortable even for running but I disagree. IF considering running also, I'd get the Flash, but, if that's not a concern, I think this one is better because of the extra pockets and since the bag is wider, it's a little easier to put and get stuff out of the bag.

Very Pleased with this Great Bag

I did a lot of research before I decided on this bag in the color I wanted. My parents actually sent the standard Kompressor to me for my birthday instead. After receiving the Kompressor, then swapping it for the Plus, my decision in the Kompressor Plus was reaffirmed. The Plus seems to have a lot more room, and the additional external pocket has been nice. A couple things I'll say about the bag.
1) Citronelle = green, not yellow.
2) The external mesh pocket is very roomy. The centered, vertically oriented zip at first seemed to make things difficult to get in and out until you reach for the pocket without taking the bag of your shoulders. Just reach back around and the design makes perfect sense.
3) The sternum strap is all that is needed for this bag. At first I worried about not having a hip strap, but I recently took this bag, fully loaded, on a 5 hour dirt biking trip on rocky trails. I was able to focus on riding and forget the backpack because it always stayed right close to my back.
I have used this bag on the 10+ adventures so far, and I use it for frequent the day to day use. It has held up well and is the perfect day pack. I highly recommend this bag as a lightweight, simple but elegantly designed pack for most adventures.

Could have been great, but so many bizarre design decisions...

I wanted to love this pack so badly. There are some good things about it, but many things that make no sense. I bought this for a few reasons:

1) to travel with - as an ultralight bag that can be easily stuffed into a larger bag, and then taken out for flights, day-trips, etc.
2) to run with - I wanted something ultralight that I could run a couple miles to work with, with a day's worth of clothes inside (#1 above was the main reason, but I figured this would be a nice bonus)
3) As a compression sack, if I ever needed one while camping, etc.


The good:
- it's light, of course
- it's comfortable. MUCH more comfortable than I thought.
- a large (I have a 16" screen) laptop fits in the back pocket where the foam insert is.
- didn't bounce around much at all while running with it, despite the lack of a waist belt
- folds into the top pocket, which is very nice

The bad:
- this is not a compression sack. The regular Marmot Kompressor has compression-like straps and works much better in this regard. If you compare them, you'll see that this pack has its two side straps oriented sideways, so you really can't compress things vertically as you can in the Kompressor, which has all 3 straps oriented vertically. Futhermore, the amount you can tighten the straps on this pack is limited because they are looped at the ends. Difficult to describe, but you can't pull the strap all the way.
- The large outside pocket drives me insane. It's huge (basically covers about half the pack) and is one huge pocket, so everything is all over the place. The zipper, as you can see, is in the middle, so it's difficult to put larger things in. It takes a lot of effort to put just a normal paperback book in. If the zipper were on one side, you could just slide it in, but since it's in the middle you put half the book in, then kind of bend it and fold it until you can the other side in. Finally the pocket is made of mesh so that people can see everything inside it (no I really don't want people to see my ipod while I'm walking around Guatemala City, thank you), and the contents are less protected from weather. If there were a few smaller pockets (including open side pockets for a water bottle) enclosed with the same ripstop material, this would be infinitely better.
- When the bag's closed, the top pocket is "curved" around the front of the bag, so you really can't put anything in there. Anything rigid (even a pen) will prevent the bag from being closed as it's intended to be. This pocket is pretty much useless except for really tiny things, and its only use is really to hold the pack when you fold it in there.
- Two cords that don't really do anything, near the top. They're just loops. Maybe you can hang stuff from them but I think they would bounce around a lot.
- Says it's hydration pack compatible, but all other packs I've seen that are have a slit for the tube at the top of the bag. This has a hole like that, but it's at the bottom! I am absolutely clueless about what the hole is for. If you use this as a hydration pack, you're just going to stick the hose through the top of the pack somewhere. It's possible, since it doesn't close with a zipper, but would be a bit clunky.
- Like many packs, there's a stretchy part of the chest strap, that is supposed to expand when you connect the clip. However, it's doubled up and takes too much force to expand it - so if you tighten the chest strap and connect it, instead of this elastic part being expanded, the two shoulder straps just come closer together, and you're left with this unsightly loop on your chest.
- the top pocket (which the back stuffs into) could have been a lot smaller. When you do it, it can be further compressed by at least 30%. I wish this pocket were smaller so it would take up less space when stuffed in.



In short, I do like this pack - it just could have been so much better. If you are trying to decide between this pack and the regular Kompressor, like I was, the *only* difference is the size, because the extra pocket on this one is close to useless.

Responded on

In short, I have to agree with most of this review.

What bites:
The compression straps should be angled much more severly for true compression. As it is, they sort of compress the middle and give the bag a "muffin top" look. The loops near the drawstring are intended for ice axes/poles (see explanation below in this thread) but are missing a small hook to make it easier. Finally, those freaking zippers: man I HATE those things. If you have contents in the pockets it all falls out when you open it due to their vertical nature: lost my brand new headlamp this weekend because of that.

What doesn't:
As @j.a3892736 points out (below) this is an ultralight pack. It comfortably holds 10 lbs of gear, and stashes easily away easily. It's not meant to do much more. I've been using mine on long day runs/hikes to stash a fleece, shell, large bladder, Fat Tire (now in cans!) snacks, poles (if needed) and shoes (if needed) and have been pretty happy with it. It also travels well (but I don't also don't use the mesh pocket when traveling). The material has held up pretty well so far. I shredded a similar Mtn. Hardware pack a few years ago (which BC refunded!) and this seems to hold up much better.

In addition to the "drawstring" which keeps...

In addition to the "drawstring" which keeps the top of the pack closed, there are two additional cords which don't seem to do anything (they don't tighten the back in anyway, they're just kind of attached to the bag as loops). What are these for?

Responded on

They're compression straps. They're there to cinch down the body of the pack so that you don't have dead space/to make the pack smaller.

Responded on

@Thomas Ogasawara - not sure we're talking about the same straps. I don't' mean the flat ones with the clasps (that you can see in the photo above). These are just two "loops" that hang off the bag, near the drawstring. They would fit around your wrist or so, and are the thin (maybe a couple milimeters) circular cord.

It's as if they took cord, made a loop, and attached one part of the loop the bag and let it hang. I don't see how they could be used to tighten anything. Are these what you mean?

Responded on

I believe you're referring to the ice axe/pole loops. The head of the ice axe/tip of the collapsed pole sits in the flat loops on the bottom, and the shaft is held against the bag with the bungy loops that are near the drawstring. It's just short of a good design: most packs with this same setup have a little hook on the bungy loops that make this a lot easier (e.g. Lowe Summit Attack 30).

Is the hole for the tube of a hydration pack really at the *bottom* of the back? If not, what is that hole for?

Best Answer Responded on

Best guess is that it is a drain if you put snowy/wet items inside.

Responded on

The top of the hydration sleeve is open, so there is no need for a hole.

How well will this pack hold up in light to moderate rain? Should I plan on a rain cover?

Responded on

The main fabric is impregnated with silicone, so it'll shed water a bit. If you're worried about a downpour, a rain cover won't help anyway. Get a drysack for inside of the backpack.

Perfect

The other reviewers are forgetting one very important thing: this is a 12-oz pack. No, it's not super-heavy duty, indestructible. It's not super-heavy anything. It's way light. I love it. I strap my snowshoes on the outside using the compression straps. I carry water, layers, nom-nom's, and a camera. I bag 12,000 and 13,000 ft mts in winter with it. It's a no nonsense, minimal pack, and that's exactly what it is. It's perfect.

Good in theory, falls short in practice

It's light weight, packs down small in a larger bag, but it left me feeling completely underwhelmed and disappointed.

Even with the foam backing, the bag is still really floppy. When loaded, the foam tends to begin working its way out of the bag which looks sloppy as well as just being annoying.

When partially loaded, the bag lacks the rigidity to hold any shape, and the contents pool up at the bottom in a big glob. This becomes a catch 22, because the bag's straps aren't really padded enough to hold much weight, but the bag definitely feels better on the back when it's stuffed to the brim.

In the end, I found a slightly smaller, heavier hydration-capable bag from Osprey to be a more useful approach. I pack items within this bag, then pack that into the large trekking backpack. Sure I'm sacrificing a bit of weight and space in the large backpack, but I'd rather have a solid platform to make the day hikes enjoyable than be such an ounce-counting nut job that I have to be miserable during the fun parts of my trips because I have a floppy stuff sack for a daypack.

Crap

It seemed good at first - lightweight and compactable. It got caught on a tree branch and got a huge rip on the 6th use. My other backpack lasted about 10 years through constant abuse. So I guess there is a price to pay for crappy lightweight material. Also Marmot wouldn't have it fixed for me. So much for standing by your products and a 'lifetime warranty'!

Responded on

I don't see how you can expect to repair physical damage caused by you. This should fall under abuse. After all it is a super light design.

How much weight can the marmot compressor plus backpack safely hold?

Responded on

Hey Chris,

I wouldn't suggest going more than 15lbs for a comfortable carry. While the backpack can take it, you might not be able to.

slim design

this is a very small compression pack. it is narrower than the picture looks and only covers a small portion of my back. will definitely work for my purposes. the foam backing is pretty thin and if it is used as a seat, you might what to throw some fluff under it...

Responded on

Is the lack of a waist strap a problem? Or is the chest strap enough to keep it from moving around?

Responded on

not a problem at all...however the draw string closure at the top has broken. sending it back to backcountry so they can deal with the warranty issue
