Review on TRIWONDER 5.5L Hydration Vest For Running, Cycling, Hiking - Water Backpack For Trail Races And Marathons by Frank Mayes

Excellent vest for outdoor activities. I have used this vest on several occasions (cycling and running) and have only one minor issue. Since I will mainly use it for running, I found that when I do run, my hands will hit/rub against the water bottles which are located in the front of the vest. I don't know if this is really a knock on the vest since I do tend to run with my hands close to my side/chest. It wasn't significant, but enough of an issue for me to buy a CamelBak 1.5L bladder to put in the rear and leave the water bottles at home. The water bottles were also only 8.5 oz, so they were really not enough for me during my long runs. If you tend to run with your hands close to your chest/sides, I would probably opt for a bladder instead of the bottles. I now use the front pocket which are designed for the water bottles for snacks/nutrition.There are numerous pockets in the front which are easily accessible and one of them fits my IPhone SE. As explained above, I use the others for snacks/nutrition for my long runs and bike rides.There is also a very large rear compartment where you can put a water bladder as mentioned above along with larger items such as keys, wallet, etc.One feature I really liked is the front straps also move up and down, allowing you to find the most comfortable spot on your body. The vest is really lightweight and once you adjust the straps to fit your body correctly, it does not move or bounce around. It did take a little getting used to, especially since I have never worn a vest while exercising, but once I did, I have not had any problems/issues. You will have to play with the straps a little to find the perfect fit. I found if I put them too tight, it would hamper my breathing and if it was too loose, it would bounce around a little. However, the straps are easy to adjust, even while exercising.Would definitely buy this again, but as described above, would get a bladder instead of the bottles. This is a personal preference and really is more of an issue with my running style than the product I believe.
