Agree with them on sizing, but think that they've shot themselves in the foot a bit with the name. They've had loads of publicity via magazines, websites, forums etc. over the last year but by their own admission have only had a turnover of 40ish k. I wonder if this is due to the branding?
I'm a tall-ish skinny guy, skinnier than most cyclists and I have trouble with cycle clothing, and I wouldn't dream of wearing a "skinny guy, look at me" jersey.
One of my mates who is the proverbial fat lad at the back hates this brand with a passion as he does struggle to get clothes, and sees cycling as a way of getting fitter but thinks that this brand brings unwanted attention. Not all "fat lads" are jolly and confident enough to bring attention to themselves, same as us skinny guys.
I think the Dragons, especially Peter Jones got it right. Some cyclists will like it as it's a bit quirky, but I think it excludes a lot of their potential customers. With a better name and less obtrusive logos, they could be on to a real winner as there is a gap in the market for more realistic sized cycle clothing. Good luck to them though, maybe they could keep the FLAB as a brand within a brand, and have a less controversial name for some of their products.
