Quality of product is excellent. In this cold weather, the thermals have done the job.
My only gripe is.. er. when needing to use the loo. Although there are two zips on this, it can get a bit awkward if you need a number 2.... no back flap, which is the type of thermals long-john that I did want. Im 5 foot 10" and it does tug a little on the shoulders like it was made for someone a little smaller. Other than that, Ive been wearing mine as much as possible with all this minus temperature we've been having and you wont even notice you're wearing it when you are out and about.
