Our 100% merino wool roll neck jumper is a popular addition to our Merino range in the colder seasons We source the wool from the acclaimed Zegna Baruffa Mill in Italy. We’ve used a super fine 27 gauge jersey knit in a dark red / burgundy marl, with a ribbed neck, cuffs and base. The jumper is fully fashioned with a dropped back shoulder seam, to create a clean profile.

Thank you OS

I am new to the world of roll necks: but the OS "treath" in navy was an excellent intoduction.

Top quality & a great fit & a big thank you to Ridian too for the usual OS first class customer service when dealing with my query.
