First impressions aren't great as the material is quite ridged and doesn't feel comfortable. Id gone for the Gildan because of the greater colour range, but the material compared to the Uneek Jersey Polos which I got last year is definitely not as good. Re. Sizing - mediums are good, the larges are bigger than normal larges, but the small is smaller than normal. I will update after the garments have been washed, but based on how the material looks/feels Im sceptical about how long these will last.
