Phone. Flask. Vest. V2.0: Ideal for running and riding less than 2 hours.

Minimalist pack great for races and shorter workouts. Stays in place, and the flask is easier to keep clean/dry than the reservoirs in my larger packs. Wasn’t sure how the front facing pack would work for SUP where the body is often bent forward with arms extended in front. Also wasn’t sure how the pack would fit my body type. Pleasantly surprised on both counts. The back pocket has some stretch and fits my phone and keys, though without much room to spare. The straw doesn’t seem to stay in its dust flap while in use, but that may just be how the pack sits on me. Overall, a great addition to my gear vest and 1L and 2L packs.

After three runs one ten miler two sixteen milers lots of climbing and very technical. Giving this product a five star normally I wouldn't because I believe five stars is when you don't have to wear anything. I switched out the water bottle for one of my five hundred ML fits just as well if not better. Was surprised how secure it fits I am on the more muscular side of ultra runners due to my job so I was worried the small would not fit but it ended up working well. You adjust it as you finish your fluid and having your phone up front is nice. if it had a couple loops for poles it would be even better. I would use this on a well supported ultra or no supported short run. I recommend this if you don't fiddle around much with your gear during runs this works well for you.

I've only used the PFV on one occasion and my goodness, I kinda forgot I had it on. I'm not a well endowed woman so I was still concerned about how the PFV would 'sit' on my chest. Truth be told, it wasn't a problem at all. It was so easy to refill my water and of course to drink from the flask. I was running a trail w lots of loops so I didn't need to use the back compartment other than for my keys. I usually wear shorts w pockets so i kept my phone there. I anticipate this being a top contender with my single barrel.

Needed something lighter weight to take water and lightweight rain jacket with me in the PNW. Works great. 6 mile hike barley new it was there.

I love this thing. It fits everything I need for a run of less than 10 miles and can even fit my Samsung S8+ phone. It's perfect and exactly what I was looking for.
