More than a decade ago I ended my exclusive reliance on the 10 ounce/300 gram cloth that my tailors had me in for much of my life in California. Spurred by arguments that heavier, 15 or 16 ounce (450-480 grams) cloth hangs better (it does), wrinkles less (absolutely), wears warmer (so true) and is perfectly comfortable in heated rooms (ahem), I built a winter wardrobe in tweed and flannel. And this year I have realized that I rarely wear said clothing unless I am travelling to a place with an actual winter, an activity I strive to avoid. For though it is fine on days when peak temperatures are below 55 degrees (13 C), in 65 degree sunshine I find heavy cloth uncomfortable, preferring to wear something mid-weight. The trouble is that on too many days my ten ounce mid-weight cloth is not warm enough.
This is probably akin to splitting hairs, but for 2013 I am resolved to add a suit or two in a weight closer to 13 ounces/400 grams than ten ounces. And for wear away from the city I am drawn to a worsted tweed like the swatches in the photo.
There are two principal sources of mid-weight worsted posing as tweed, the one being John Hardy's 12 ounce/360 gram Worsted Alsport in the photo and the other Porter & Harding's 11 ounce/330 gram Glorious Twelfth. Of the two, I like the Worsted Alsport for myself (the company's website photography does not begin to do it justice) as it is a bit heavier and the designs are distinctly tweedier to my eye.
I think I will try the green pinhead with an orange overcheck to the upper left of the photo for fall.
