Fluid™ 32 is rated 4.5 out of 5 by 13.
Rated 5 out of 5 by from Super light and super comfy, dries fast, but not army tank. I got this pack for work as a guide in one of the wettest hiking environments anywhere. After a *complete* soaking, I was able to air dry it and get it mostly if not all dry before the next day's work. (Wish I could say the same for my shoes!) It's comfy and the pockets are all in the right places, and the closures and synch-compression system were great. On the down side: I took the metal bar out shortly after buying the pack, and I was never able to get it back in all the way. The red color bleeds a bit. I love the stretchy mesh pockets, but they can snag. The cushion straps show quite a bit of wear. After hundreds of uses, I'm retiring this pack from work use, but I'll still use it for private hikes. If you want light-weight without sacrificing comfort, this is the pack to get. Now I wish they made a 45L version. . .

Rated 5 out of 5 by from Best pack ever This pack is the most comfortable pack I have ever owned. Super roomy for day trips and 2 overnights. The fit is fantastic...love the padding, lightweightness,side pockets and the strap on the back that I can just slide my snowshoes into when I need to carry them. PLEASE MAKE THIS MODEL IN A LARGER CAPACITY SIZE!!! I am determined to make this my 5 day Washington Enchantments backpack trip bag. would LOVE lOvE LoVe it if you made it in a 55 liter, please. Will write a review on my 5 day trip soon. “The civilized man has built a coach, but has lost the use of his feet.'' Ralph Waldo Emerson

Rated 4 out of 5 by from fluid 32 I use this pack for self supported efforts on ultra efforts/runs and hikes when running the only issue is the left top strap can dig into your neck but my pack is fully loaded with some minor padding added this should take care of that// Alohas Meep

Rated 2 out of 5 by from I wanted to like this pack but either I am too short for the frame, 5'5", or the design is quite poor in that the metal support rod hits the top of my neck when I look up. The top loading is easy to deal with and the cinches work well to keep the pack stable. I regrettably returned the Fluid 32.

Rated 5 out of 5 by from Great Bag! I have used this bag for a couple of day hikes and my only complaint is the slot to route the hydration hose is a little too small. Other than that this is a great back with a good suspension system. Very comfortable with about 25 lbs in it.

Rated 5 out of 5 by from Excellent Larger Day Pack This pack was exactly what I was looking for. I originally had reservations because of previous reviews discussing the amount of straps, but they all have a function and have been very handy so far.

Rated 5 out of 5 by from Still looking for what it can't do... ...but I can't find it. A day's worth of climbing gear? Check, easy. Short backpacking trip? Check. Five-day front country trip...with extra shell and layers for a ski day? Done. Seven-minute sprinted connection in the world's busiest airport? Oh yes--no kidding. I barely even felt the pack on my back--no clumsy bouncing or "wide load" problems moving through a crowd--which is probably why I made the plane. AND it fit easily in the overhead. Perhaps more useful for you: it runs true to size, is very adjustable for a daypack, and fits this female well (I usually can't get unisex packs to fit right). The suspension is fantastic. As far as capacity goes, I'd swear it's bigger on the inside. It's a great blend of simple overall design and useful details, like the mesh pocket on the underside of the lid, the elasticized front overflow pocket panel, and the well-designed hydration bladder sleeve and ports. This is a winner!

Rated 4 out of 5 by from Fluid 32 Overall, a great pack and a much needed personal upgrade. I'd recommend it, but with two reservations: 1. It is festooned with needless (and needlessly complicated) straps. There are so many loose ends that it looks like a tattered big wall belay. The hip strap takes the cake for pointless over-engineering. Why does a day pack need such an over-the-top system? 2. The closures, while snazzy, are needlessly complicated and defy one-handed operation. Again - it's just pointlessly over-engineered. Case-in-point: the hook enclosure for the top flap is goofy and hangs up on every attempt to open it. This is deeply annoying, like a zipper that won't close without repeated tugging. Mine is destined to be cut off and replaced with a more functional buckle. Still, a very nice pack, but if you're looking for straightforward functionality, this ain't it.

Rated 5 out of 5 by from Perfect for a Weekend Backpacking Trip! Surprisingly ample room for my two-person tent, 20 degree bag, food, water, clothing, etc., for a 2-night excursion into the wilderness. Good overall design.
