It's officially called a 'crew neck sweater', but I think it's better suited to be called the Barbour Steve McQueen Randall sweatshirt.
Part of the new Barbour Steve McQueen collection of clothing inspired by the iconic actor, this is a rugged, vintage-style sweat, available in various colours, each one with a felted 278 motif, quilted elbow patches and a heavy wash for that vintage look.
The 278 you ask? That's apparently McQueen's registration number for the 1964 International Six Day Trials, in which he raced for team USA. £89.95 is the price – there's a (cheaper) t-shirt equivalent too.
