Thick, warm, cosy feel - just what was needed. XXL was long too. Many M&S items are too short, made for wide, not tall.

My grandson wore this vest to an outdoor event and didn’t feel the cold during what was in his words “a freezing evening”. Very pleased with it.

Mind the quality and feel the width!

Yes, I recommend this

Immediately upon removing the t-shirt from the packaging the feel of the material was exceptional. Trying it on I could feel a real protection from the cold without being too weighty.

Product Cosy and Warm

Yes, I recommend this

Bought this for my partner and he thought it was very cosy and warm. The only one drawback was that I had to order online as they were not stocked in store in York for the Maximum warmth despite there was lots of the leggings.
