Review on Ultimate Trail Running Hydration Vest: TRIWONDER Backpack for Marathon - Stay Hydrated on the Go! by Jason Childs

This vest is great for carrying your phone (fits Iphone 11) and keys. For me it's a bit small. I ordered L-XL and it just fits. I didn't feel any rebound when running. It would have been nice if it came with a blister because the pocket seemed small for most blisters I've seen. I also like it because it's very light and doesn't bounce. The side slats had to have Velcro because they are so flat that something could easily fall out.
