So, what...three months?...after I got new riding gear, I finally had the chance to give it a real test. This morning it was in the upper thirties, no big deal. Got to work snug as a bug, more or less. But sometime today we fast-forwarded right into the middle of November, with cold rain beginning midday under leaden skies. By the time I left work, it was raining steadily and the temperature had settled into the low forties with gusty winds.
I can happily say that my new Fieldsheer suit passed with flying colors. I rode about thirty minutes at interstate speeds in steady rain, with no leakage and nothing untoward to report but the occasional cold spot here or there—mostly on an elbow, where odds are I hadn't secured the vents properly.
With the Gerbing jacket cooking away underneath, I was comfortable and dry all the way home. As a bonus, neither the jacket nor the pants had their liners in place, so I suspect if the liners were in place I will be fine in precipitation down to freezing, or dry down into the twenties. Looking forward to this winter!
Addendum: 38 degrees this morning, steady rain. Adding the jacket liner is great. Warmer with negligible additional bulk or constriction. The balaclava goes over the jacket collar and seals very nicely. Unfortunately, gravity still makes water run down into my gloves, soaking them in short order. I can't feel my left fingers or thumbs fifteen minutes into my commute.
