Ran my first half marathon using this vest. It was very comfortable, held plenty of water, and had enough places to stash fuel plus personal items.
Overall the vest is great, fits snuggly without any chaffing on long runs. Pockets are great for holding gels and small soft flasks. The bladder is nice but isn’t insulated. The back is vented but transfers too much body heat to the bladder. I fill the bladder half ice and half water and 6 miles in a long run it’s melted and the water is starting to get warm. By mile 10 it’s warm water. Had to purchase a separate insulated bladder that helped much better but that’s just added cost. Otherwise it’s actually comfortable, versatile and lightweight.
This vest is great. I use this for all my runs and mountain bike rides now because it fits so well and has so many convenient pockets for accessing phone, snacks, glasses, etc. I do not understand complaints about the chest strap fasteners because I find these much easier to use than your typical buckles. Snap on quickly and release with a simple pull on the top tab.
I just got into running and this pack is incredible. It comes with a 1.5 L bladder that works really great. it has 2 pockets for soft bladder water bottles. 300 or 500 ml soft water bottles fit perfect.
Great fit, nice pocket variety and the bladder is good for 8 mile runs maybe more…
