Hotlips 2 Piece Set

The lip shape actually hugs the rim of my titanium mug perfectly, so no more burnt lips from that thin metal edge. It's a small thing, but the silicone feels sturdy enough that I don't worry about it slipping off when I'm hiking with a full mug.

I was a bit skeptical about using silicone on a hot mug, but these lips grip the edge securely and create a comfortable seal that prevents any burning or spills.

The silicone is surprisingly sturdy, so I don't worry about it bending out of shape. It’s a clever little workaround for my titanium mug, though I do wish the set came with some kind of storage pouch.
