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

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.

The PFV is great for short runs and cycling. Plenty of room for water, phone and small items. Items are secure throughout the run. The one knock is the adjustment straps. They are in the rear and difficult if not impossible to reach while on a run. Unless you're with a partner you have to have it just right when you put it on. For reference I wear a men's size L tee shirt and bought the XL PFV.
