Extended time use - Peltor Aviation Parts & Ac: Camelback Gel Sealing Rings HY80

If planning on using the comtacs for more than a couple hours at a time, the gel cups are highly recommended. Did an all day shooting class with the foam, and by noon was feeling the discomfort/headache setting in. The gel cups are better for heat/head temps too. Seals around ears about the same. It would have been nice to come standard over foam, the one downside Ive heard is that they do wear out the form faster and need replacement eventually. Nature of the beast in gel form.
