Do SwimEars block cold air even though the mesh is an open structure?

The mesh is an open structure, which does allow some air to flow through while blocking water. This is one of the reasons why they let so much sound through. If you blow trough the plugs from the gel side there should be some resistance. This is enough to avoid excessive circulation and will help keep the air inside your ear canal warm.
