A vest like this one is always practical, no matter what sport you do: mountain biking, jogging, skating, climbing etc.
Real light material (only 152g size M) which you can fold really small so it won’t take up too much space in your backpack. Windproof and breathable. Long front zipper with comfortable chin guard. Small pocket on the chest with zipper.
Size is Unisex, it fits therefore women and men! Men should eventually order one size bigger though.
34/36 ~ XS, 36/38 ~ S, 38/40 ~ M, 42 ~ L
