I have a carmel UK Workman's and a blue denim UK on order. According to the UK site both these kilts are 12 oz material. It will be interesting to compare how the weight of these kilts feel as compared to my 16 oz, 5 yd wools and my 13 oz, 8 yd wools. It would not seem that these UK's would feel as heavy as either of these wool kilts, and neither leave me feeling tired after wearing them all day. As arrogcow mentioned, it may be due to everything that is being carried in the kilt.
