3L Vest, Size 3

"A great hydration vest with a L capacity, featuring a back pocket and two front pockets for 350-ml water bottles. It’s very lightweight, comfortable to wear, and stays comfortable even on long rides. The only area for improvement would be the chest straps, which tend to slip under the weight of the water bottles and my phone. In fact, I had to tie a double knot in the center strap myself to limit its stretching and prevent it from coming loose during exercise. Aside from that detail, I’m very satisfied with this purchase and recommend this product."
