It's midsummer in the upper midwest, so I am rotating my two Willis & Geiger M-421s, and then only if it's windy, rainy or I need lots of pockets. The W&G bush poplin is great goods, tightly woven enough to shrug off light precipitation tho not water treated in any way. Best part is, I got the 2nd jacket at a very reasonable price due to some minor spotting on the right front. (I'm gonna patch it over with the insignia of VT-6, the Devastator squadron that got all but wiped out at Midway.) Aren't patch-flap pockets way cooler than plain slit pockets? I think so!
