Anyone after a cheap mid layer, wear a size 42 jacket/suit then you’re in luck - M&P have these usually £50 gilets going for £20.16 (free p&p for another £4.84 of tape/parts etc) Mine arrived today and it’s very snug - fleece lined, thick but stretchy - it’s similar but more substantial than my cycling “perfetto” windbreaker gilet that costs £90 new. Bargain - but just in 42/M https://www.mandp.co.uk/products/rst-thermal-wind-block-gilet-black-ch04209
