I was looking online at rain jackets for bicycling and I discovered quite a few rain jackets offered pack down small.
For example,

I have worn a bicycle windproof vest with a mesh back instead of a windshirt for hiking because I had one for bicycling and the backpack protects my back, and so I was looking at lightweight rain jackets for bicycling for my next lightweight rain jacket for hiking.
Has anyone had experience with a rain jacket for bicycling used for hiking?
