Not sure if it's the Kelly Green Plaid, but the weight of the woolen fabric seems to be lighter than my other five woolen SK caps. Also, the crown of the cap seems a bit more 'bulbous' than most of my other caps - especially the older ones. When I pull the old caps down firmly to the tops of my ears, the crown fits neatly on my head. This one seems a bit more 'blocky.' Not sure if that's a change in the pattern or just another Michigan hand-sewn cap. I'm not complaining - these are just my observations. I'll happily add this one to its 6 older waxed cotton and woolen brothers and sisters!
