These are a pair of Swedteam Lynx Light Trousers in orange. The official size is 44R, but given the elastic waist, they were just fine on me at a 40R (which is what they measure round the waist), 31" inside leg. Great pair of hiking/working trousers with a super stretch fabric, I've not worn them at all. I paid £90 for them, yours for £45 posted.
