Fluid™ 6 is rated 4.6 out of 5 by 8.
Rated 5 out of 5 by from Great little pack! My 6-year old granddaughter was REALLY bummed when she thought that she couldn't get a Fluid 6 like her sister's. I was finally able to find one on Columbia's online store, and she is thrilled!! We even had to take a short hike after school yesterday so she could use it. Now my adult son- long-distance runner, enduro motorcyclist - wants one, too.

Rated 4 out of 5 by from Long Run, All Day Pack I've yet to fill this pack up for outings up to 4 hours. I can get everything I need for a run or hike in the mountains and it carries great. There is hardly any bounce and the straps can be easily adjusted as the contents are reduced. My only issues with the pack are a lack of loops to hold trekking poles, The side bottle pockets are really hard to get bottles back into without taking off the pack and I wish there was another bottle pocket on the strap up front. The pack rides off balanced with only one bottle up front. Overall, it's a great pack for long outings and I hardly notice I'm wearing it.

Rated 4 out of 5 by from Great, but a few details... Great pack, use it nearly daily for trail runs to stow gear as I heat up. Two annoying issues: The sternum straps have tons of placement options along the shoulder strap - except that they're sewn in place. Should have been a different config on that piece. The rear elastic webbing: the clip to hold the whole thing in place is basically useless, so the over-long cord comes loose. Would be cool to see those addressed in the next iteration, since they're nothing that would add to material costs.

Rated 4 out of 5 by from Love it I really love this pack! There aren't many packs that I can run with but this sure is one of them! For the women out there with a bigger chest size this actually acts like a second bra if you get it adjusted right, which is awesome! Only con is there isn't any padding between what is in the pack and your back so if you don't have everything perfect you will get poked, but this is also a pro because it doesn't keep a lot of heat in. I like the little pouches in the front of the vest prefect for little things like chapstick, hand sanitizer, bags for dogs. Anyways I love it and will probably buy another one for my husband so we can both have a little day pack

Rated 5 out of 5 by from Very little bouncing, just the right size for long runs The pack doesn't bounce much, very similar to the Nathan pack. It is cheaper than the Nathan pack, but it doesn't come with a bladder. The main pocket is actually quite large, you can fit several layers of clothing inside. The side pockets and shoulder strap pockets are all perfectly positioned and sized. The pack is light enough to substitute for a race vest if you don't want to take hydration bladder.

Rated 5 out of 5 by from nice, light vest pack I'm really enjoying this little pack. I needed something that I could use for long runs in the mountains and this fits the bill. The main pack is roomier than meets the eye- plenty of room for extra clothing, food, and a few necessities. The bungee setup on the front of the pack allows additional items. It has two stretch pockets on the side that will fit your typical 20 oz running bottle, but unless your VERY limber you won't be accessing them on the run. I've used them to carry a small camera on one side and a cell phone on the other. The pack carries really nice with little, to no bouncing. Much better than any other pack I've used for trail running. The small front pockets are handy for electrolytes, gels/cubes, sunscreen and the like. a few nitpiks-I do wish the main pack had a small mesh pocket that one could put things like a first aid kit, headlamp, map, etc so they weren't just floating around in the main pack- this would add very little weight and would be most welcome. The straps that adjust from the bottom of the pack are prone to loosening, they are easily accessible so it's not too big a problem, but I think easily solvable with perhaps a hardware change. One larger pocket on the front of the vest would be very handy and again add very little weight. All in all, a very nice pack for your long runs!

Rated 5 out of 5 by from Great light pack Awesome pack. It carries a reservoir or bottles well. Also holds just enough food and gear for an all day excursion. It would be nice if the front pockets were bigger. But overall I am very pleased.

Rated 5 out of 5 by from Fluid 6 Delivers I needed a pack for cycling, light hikes and excursions, and this is the perfect pack. It's super comfortable and holds just the necessities when I opt not to take a full-blown pack of supplies. Being a female, I'm particular about straps rubbing but this pack was well-designed. I recommend adding this one to your collection.
