Our Pick of the Best Gym Base Layers

Nobody here is paid to push a brand. Gemma, Aisha, Leanne, Chloe and Imogen went through everything in gym base layer the way you would on a lunch break, scrolling, squinting at the fabric, checking the price twice. What made the list is what they'd actually put in their own basket. We look for pieces that wash well, sit right and don't cost silly money for what they are, and we mix up the shops so you're not just looking at one high street name over and over. Prices and stock come straight from the retailers and change often, so it's always worth a quick check before you buy.
