Looking for a jacket to protect you from cooler, blustery days? Check out the Pour Osity Jacket from Columbia. This jacket is considered to be 2.5 layers and will both keep you protected from the elements thanks to its Omni-Dry waterproofness or Omni-Wick EVAP wicking.
If you're out on an extra humid day, Columbia has include long side venting for allowing in a cool breeze. Two zippers per under-arm allow for partial venting, or complete airflow. The two hand pockets are quite deep and a cellphone can stand completely upwards and not even reach the top of the pocket (or accidentally fall out). They are also waterproof thanks to the seam-sealed zipper and an inner pocket.
The attached hood is spacious enough to accompany a helmet but adjustable with the drawcords to keep it snug around your head. The wire brim can be adjusted to your liking for visibility
There are nice little features such as the tail of the jacket being a little longer than the rest, and the chin having abrasion resistance. Oddly though, there is no loop inside the jacket to hang it on a hook. I like the high visibility of the blue colour and the contoured sleeve cuffs that you could velcro tightly around your wrists to deter water.
