This is the real deal. Thick wool and is remarkably heavy. A bit scratchy but it's designed for a tough job so it's going to be a bit rugged. As far as I can see it's a genuine royal navy sweater the design of which has not changed in 70 years. Ordering and delivery was as slick - as you'd expect from a shop with a Royal Warrant. 10 out of 10 for product and service.
Just been outdoors for a few days and while others in the party complained about being cold - I was as warm as toast.
This is a top draw sweater, however the first one delivered had a hole in it! So had to send back and got another one!
Excellent quality and service.
