The Q36.5 Adventure Tech Merino Jersey is soft and stretchy and good for most UK temperatures you’ll encounter in the short sleeve half of the year. But the Adventure Tech Merino Jersey is indeed a relaxed fit, as billed, and I suspect I might have been better off with the medium after all. The Isadore Signature Merino Tech Jersey (19 per cent merino) has an RRP of £155, for example, while the latest version of Velocio Men’s Merino LUXE Jersey (71 per cent merino) is £152. ConclusionThe fabric of the Q36.5 Adventure Tech Merino Jersey is wonderfully soft and the comfort-oriented fit means it doesn’t feel at all constrictive. Of course, you can buy merino wool cycling jerseys that are 100 per cent merino wool – usually with a slight, or indeed overt, retro vibe.
