Review on Opliy Hydration Pack: Lightweight Running Water Backpack with 2L Bladder for Women and Men by Jeff Figueroa

I love this set so much! Fits my 4 year old perfectly with plenty of room to grow. Other backpacks I found didn't fit his shoulders properly. The only reason I gave this 4 stars instead of 5 was because I wanted the water bag to open at the top and not with a screw cap on the side, this cap makes it very difficult to air dry the bag, so he will go bad much quicker than my other water bladders. Aside from that part, the packaging is amazing! Definitely recommend
