This vest is, in a word, amazing!
This vest stole my heart from the moment I tried it on. It smells richly of leather and freedom. It calls you to adventure and then jumps in the saddle with you. If this vest had a name, it would be Sam Elliott...rugged and handsome, yet soft and deep. It's supple, surprisingly light, and delightfully warm, without being too hot. Buy this vest, you won't regret it (neither will your wife).
For reference, I'm 6'2.5", 185 lbs. I tried on multiple sizes in store and settled on the 40...it fits like a glove.
