EDZ have a number of their excellent base layer garments on sale - ideal for motorcycling and other outdoor activities. https://www.edzlayering.com/collections/long-sleeve-tops-1 - Merino wool tops reduced from £50 to £30 If the prices are still too high for you then have a look at Millets (and presumably sister brand, Blacks) at the Peter Storm sale. https://www.millets.co.uk/mens/mens-clothing/baselayers/ - polyester long sleeve top a tenner from £20 I use both. The EDZ will last you years and the sizing is consistent. Peter Storm is Millets' own brand and is batch made by multiple makers, so the sizing can vary between individual garments. Millets has a good returns policy if you order online. I take the polyester tops on tour - they rinse out easily and dry quickly so the shirt worn on the bike today will be ready to use again the following morning. This reduces the amount of clothing you need to pack.
