Great for Sweeping Hearts...and Courses

  • Familiarity: I've used it several times

Is that a directional marker in your pack or are you just happy to see me? Those aren't mutually exclusive...
The Fastpack 25 lets you slip in marking flags, wooden stakes, and previously-shed clothing right next to your bladder. After the first 15 minutes of turning around quickly to see who is following you, you realize that's just the flags whispering in your ear. Because you forgot about your load. The FP25 holds on to you tight and makes sure to flow with your motion and not bounce around awkwardly. You can stay hydrated with sips from your bottles, perky and high on your chest. There's plenty of room under them to stuff flagging in the pockets or keep your phone handy for documenting your exploration. Need some protection? There's a zipper pocket in the back to keep your toys safe and secure. Two side pockets and a larger back pocket outside the main pouch give you options to air out any sullied accessories. Don't be shy, give the FP25 a try.

Nearly Perfect

  • Familiarity: I've put it through the wringer

I've gone through several small, lightweight packs looking for a great day-hiker as well as one that could be used for one day alpine climbs such as Mt. Hood in Oregon. This pack fits the bill 99.9%. The front strap water bottle pockets allow me to leave the hydro bladder at home. It has carry loops for ice axes and enough space for gear and a small rope. The roll top allows you to expand or reduce capacity as needed. The only thing keeping it from being 100% or 5 stars are the stupid roll top buckles. They are one way buckles meaning they only click together one way. So if you've got the opening rolled up and it is not aligned, you either have to do another roll or unroll to have the buckle correctly lined up. Not a deal breaker by any means, but I can't figure out why they would ever consider using that type of buckle. Otherwise, it is pretty much perfect. My goal is to see if I can get everything in it for an overnighter--then I would truly have achieved ultralight status :-)

Solid running pack

    I use this pack for my daily commute and any extra miles I might do on the way. I average between 5 and 11 miles a day with a change of clothes, lunch, and laptop. I’ve also used the pack on a 24 hour Adventure race as well as several bike rides. The pack is exceptional for running holding everything in place with room to spare. I’m not a fan of using the pack for biking as it tends to shift around and not sit quite where I’d like it. I also find the fit a bit off with a bit more slack in the shoulders than I would like, I’m 6’4” and 190lbs wearing a M/L. I’ve also had some issues with the stitches that attach the small front pocket, but UD said it was covered under warranty I just
