This shell is a light, rain-resistant, highly visible, efficient windbreaker with ample sleeve length, a short collar and amply long tail for cycle riding. Elastic-type wrists and bottom hem. One horizontally-zippered center-rear POCKET (pouch) with 3/4 inch zipper flap. Great feature: Invert (turn inside-out) the pouch, stuff the empty jacket into the POUCH for easy storage or strap it around your waist with stretchy (hide-away) belly-bands. Has zipper-pulls on inside and outside for easy access to pouch-pocket, as you may employ it.> Not sure about amount of rain-proofing, but rain shedding is excellent in light rain for at least an hour while road cycling.> Good cycling wind protection in high-30Ëšs and light rain. Retains body heat well.> Negatives: Retains body moisture in warm-warming conditions; wearer can get soaked; Remedy: pull sleeves to elbows, open front zip. Note: I am 5'11", 183, strong shoulders; SIZE LARGE over 2 long-Ts and 1 short-sleeve lycra jersey works for me.
