I have peloton 240 hoodie in xl. Fits like a slim fitting so. It's stretchy so it works out good.
I wear it in this setup ... a xl teton short sleeve, xl peloton 240 hooded and xl guide jacket. It all works out great.... however when adding a rain layer or even utilizing the guide jacket hood. The redundant peloton hoody just bunches up around the neck. I also find the hood very undersized unless you like a body suit type fitting hood. But I also wear a 7 5/8" hat lol. And I prefer oversized hoods. I next one I get will most likely be without a hood.
