    Flow like water over the most technical terrain.

    The Mountain Hardwear Fluid 18 Backpack was built for speed and stability in demanding environments. Its mix of lightweight, breathable comfort and locked-down stability is perfect for applications like super-tech terrain or distance trail runs.

    Tough, yet lightweight ripstop nylon fabric resists tears from snagged branches and jagged rocks. The hydration sleeve allows you to route the tube from over either shoulder or from the bottom of the pack depending on your preference. Close-fitting suspension allows you to move without feeling your pack swinging around, and a stowable waist belt allows for additional support and security. Venting channels promote airflow to keep your back cool and dry. Finally, the Fluid 18 also has ample pockets to keep your smaller necessities organized, including integrated pockets on the shoulder straps, a stash pocket for easy access to snacks, and a fleece-lined sunglasses pocket to prevent your shades from getting scratched.

    great little day pack

    • Familiarity: I've used it several times

    The size is perfect for day hikes and I could fit in my essentials, and my camera. It is so light but has all the bells and whistles of a technical pack. The suspension is not that bad, although I prefer one with a better pads for the shoulder straps, but I expected this for a minimalist pack.
    The bladder pouch is nice since it is very accessible, but I wish it was a little bigger.
    Overall, the pack is awesome and so worth the price.

    Got it as a Christmas gift.

    • Familiarity: I've used it several times

    My family got me this pack as a gift. I've already taken it out several times. One of whic was in heavy rain. It is extremely light weight and simplistic. It is comfortable and carries all I need it to. The fabric is light and water resistant. Side bottle holders are a great size. Only two negative things about the pack. First, the rear stuff pouch, has extremely small opening on the sides, which makes it hard to get any items of bulk in or out...such as a shell. Second, the bladder sleeve is an awkward size. It's too small to hang any of my various 3L bladders. The only bladder that I was able to fit well was a 2L platypus big zip. It fit and hangs perfectly, not allowing it to bunch up and fall when drained. Overall, it's a good pack for a day of hiking, scrambling, or climbing. I still hope to find a 3L that will fit properly. Plenty of room in the mail pouch for a rain shell, gloves, a cap, and a meal.
