ATGATT. 12 year old 'Stitch, Shoei full face, elkskin gloves and those damned hot BMW touring boots. I generally stop riding from mid June to mid September, with the occational run to work in the early morning (come back and get the truck at lunch) just to be sure I keep the bike in good shape. How can you ride when it's uncomfortable to just stand outside in the shade?
Until I stumbled on one of these.
Coolvest
I just bought it on Thursday but only had time for a 1/2 hour ride. Saw 99F on the meter on the freeway. Still evaluating it. It's not like a cool blast from the A/C, you're still really hot but it's different. Seems like I didn't sweat like a pig like I usually do (no, not heat stroke, I felt fine and fullly hydrated). And when I got home, I just parked the bike and hung up my gear. Normally I fling off my gear and fall in the pool, just on the verge of heat stroke. Not this time. And they're supposed to work better when not exposed to wind so zipping it up inside my 'Stitch works great.
It does not depend on evaporation to work. It has frozen bars of some miracle fluid in it. The fluid changes phase at 65F. (The phase change is the point at which the most heat is being removed). It takes about 2 hours in the fridge to freeze them back to solid. If I remember my thermodynamics (jeez, that was a while ago), putting them in the freezer doesn't improve the heat removal situation much because there isn't nearly the amount of heat removed from 0F to 65F frozen as there is from solid 65F to liquid 65F. So the fridge (or anything below 65F for that matter, just takes longer) is fine.
They're supposed to work for about 2 hours when is about 95F out and it seems pretty close to this. If you ride longer than 2 hours, you can buy spare fluid packets, freeze them, and then put them in some sort of cooler in your trunk. Just change them out. A friend of mine is considering getting one for fishing on Corpus Christi bay. Get a couple of extra sets of fluid packets and keep them in the beer cooler. Should work all day.
I was considering inventing some sort of vest to put ice water in but after wearing this thing, the ice water would bave been ways too cold. It's weird how 65F can feel so cold. And the ice would not have lasted as long.
The guy that invented them sells a bunch to the guys in Iraq. Also road crews and some oil workers in Indoneasia.
This looks really promising. Won't have to arrive at work with a complete change of clothes in the bags or looking like steamed vegtables.
Off to work Monday, 80 miles round trip. I'll report back
