you got Hiking gear , unless Mountain hardwear
branched out into cycling gear, recently.. .

I'm using a cycle rain cape, now. they are not body hugging,
but entirely open at the chest.. arms extended , hold it open..
umbrella effect keeps legs dry (mudguards required)

But Im on the PNW coast it is still cool at night and often in the day too.
mid continent, where you are, varies much more in temperature..


... and my riding pace is not impressive.
