The Retro Legends T-sweat is inspired by the heavy-duty T-shirts that became popular in America in the 1950s. It became common practice to take a traditional long-sleeve, sweatshirt, and cut the sleeves off to create a garment that was easier to wear in the summer months. Eventually, garment manufacturers decided to save people the effort by supplying sweatshirts with the sleeves already cut off. That is basically what our T-sweat is. It's a sweatshirt made from a 320gsm loopback fabric. We've added French rib cuffing to the hem and sleeve ends. And that's about it. The result is a garment that we feel confident calling the 'best T-shirt in the world'. We think it's particularly suited to the UK climate, where it's rarely so warm that a lightweight cotton T-shirt is enough to keep you warm all day. Whatever the weather, you're never going to overheat in a T-sweat, but when the sun dips behind the clouds, or starts to set in the sky, it'll continue to keep you warm. It's also, of course, as tough as old boots. You're simply never going to wear your T-sweat out. That's something you can't say about your average T-shirt. Try one out, and you'll see what we mean.
