Or get larger rain gear to wear over your protective gear.
I tried Cabelas Dry Plus and on an ATV ride at 70mph in a downpour I got wet.
So I went to the Goretex at Bass Pro but haven't had a chance to use it.
We went 125 days without rain here. The monsoon storm season started now but the storms are hit & miss, very violent, but are done in 1/2 hour.
When I can afford it, I want a GOOD set of Gortex riding gear that can handle high temps (in the mid 100s) cooler temps (in the 40s) and heavy steady rain while riding AND have a lot of protective armor, even rib cage armor.
In all honesty the best is the Rain Gear you get from a Safety House.
Its real cheap
You can get em in any color as long as it is Yellow
The best Hint
Get a pair that's at least 3/4/5 times bigger than you normally wear
That way all you do is just easily slip it over your riding clothes real easy
Some good purpose built rain gear is mentioned above but doesn't (in my opinion) include the gear designed for sports stadium and duck blind use. Having said that, I think that if price is not a factor BMW and H-D offer the best.
