Are Serena & Lily linen sheets too warm for hot sleepers, or does it breathe?

I’m trying to get new sheets but my gf and I both sleep very hot and sweat a lot. I’m looking at the Serena & Lily linen ones bc she and my mom said they're really good, but I’ve splet on linen before and it felt way too thick and heavy instead of actually breathing, but I don't know if it was a good quality type. If anyone has them, how do they hold up with temperature? Do they keep you cool at night, or am I going to wake up sweating all summer?
