A much belated entry to this thread
Although this thread is "stale" some may still be referring to it (as I did a while back). I decided on the Lee Valley smock, after reading these reviews, when my Sorby's zipper went south (also the Sorby is quite warm, and short).
I like the look of the AAW and Craft Supplies smocks, particularly the short sleeves, but my vote is for the light-weight version of the Lee-Valley. The key to my decision is the "two-way" zipper. As I have a prosthetic leg I sit down often, and being able to open the nearly knee length smock from the bottom is a boon. I don't like the knitted cuffs as it can get quite hot here in New Jersey in summer, so I have cut the sleeves to mid-forearm and sewn on Velcro closures. An easy fix, and one that gives me the best of two worlds. I can cover my forearms when I want to, with the closure to keep the cuffs out of the machine - or I can roll up the sleeves above the elbow if I want the ventilation.
Another plus is that, like the Lovell and some others, one can fasten the neck collar with Velcro so one doesn't have to zip up to the collar (leaves a bit more ventilation). Pencil pockets on each sleeve, reinforced with a heavy dark material above and under the pocket (no pencil marks on the smock, no cuts from my mini ruler).
I hope that this is of help to anyone coming newly to the thread.
Best, Jon
