I wholeheartedly agree with the review by Cheeky Monkey.
I already owned these mittens in the brown colourway, purchased a couple years ago in size XS-S. The old gloves are made from relatively thick and quality sheepskin fur, are well-made, cosy, comfortable and warm.
In January 2013 I ordered a set in the black colourway, size XS-S again, but found that the quality of sheepskin used by Emu has deteriorated substantially in the space of only a couple of years! In addition the sizing has gotten smaller, leaving no space to flex my fingers inside the mitten.
The sheepskin is inferior quality, feeling almost like hard felt on the outside. Inside the sheepskin fur is substantially thinner, and I too noticed the rough interior seams that Cheeky Monkey found. They were basically too uncomfortable to wear and hence I returned them to amazon. I even tried to order the M-L size as replacement, but found the same issues, so they were also returned to amazon.
