Strange
34 R and 34 L were two different waste sizes.I purchased two pairs of trousers for my husband for work . I ordered a 34 Regular and a 34 long, When they arrived my husband tried the 34 reg. first as this is what he usually wears. It was about 3 inches short of doing up round the waist but the length was perfect. So he tried the 34 Long, Strange, these fitted round the waist but were too long, I emailed the company who also found it strange and suggested we keep the 34 long and turn them up but as I explained the knee pads would be half way down his shin .. He simply needs a 34 reg, but a true 34, which these were not.
