these are the best pyjamas I've ever had, despite the steep price, I love the fine merino fabric and they are snug without being restrictive, definitely warm and not too hot, the high neck, cuffs and pockets in the trousers are all welcome design elements.
My first set was 4 years old and still going well but were lost in a stolen suitcase.
