Do you think you can show a photo instruction on how to needle the loop back? The cuff is folded onto itself so I can't get to the underside of the outer layer, which is the pulled layer.Pulls on worsted wool knits are par for the course, IMO.
My Aero ANJ-3 was the same and they were replaced and now it's perfect again.
And the wool knit cuffs on one of my Buzz Ricksons A-10 gloves are the same but much worse - but they get an awful lot of wear on my dog walks every morning with me constantly taking my right glove on and off to pick up poop multiple times for every walk and so it's not surprising to me - so for that glove I have some suitably coloured thread and my embroidery needles out and, when I have the time, I'll tuck the errant pull and shore it up with a couple of stitches. "A stitch in time saves nine" and all that.
Now, I think I remember how this happened, but to be honest, telling the story is not going to do Eastman any good. All I can say is, with most other knits, whether used by Aero, Japanese makers, Schott, whoever, would not have suffered like this. They are all woven more tightly to let the tiny hooky thing catch a thread.
