@janelesesne thanks for reaching out! The quick answer is that here is a link to the men's rashguards we carry at REI, however it seems there might be something more that you're looking for. How "hot" is hot and what kinds of activities are you hoping to use the rashguard for? Rashguards, in general, are going to run a little warm as they are intended to provide good sun protection (high UPF) during water activities (which can help cool you down). If you don't intend to use the rashguard for water activites, there are likely better materials for hot weather that can keep you cooler. Let us know!

At REI, we believe time outside is fundamental to a life well lived.
