Sure is quiet out there. Hopefully you are all in a cave and not reading this e-mail. It is my opinion that caving helmets still have a ways to go in the design factor. For example, look how far along snowboard and bicycle helmets have come along in the last 2 or 3 years. http://www.abikestore.com/Merchant2/graphics/00000004/fujiilshelmet2.jpg http://www.bikemannetwork.com/Merchant2/graphics/00000001/Alt-Bimage/HE8140B.jpg Has anybody tried the new PMI Ventilator yet? http://www.pmirope.com/personal-gear/index.aspx?pageID=28&productID=981&productMasterID=981 I think the design problem with the kevlar helmets is creating holes for ventilation, and attaching screws and for putting in the webbing. I don't think you are supposed to drill holes in a kevlar helmet? Is that the same for fiberglass helmets?
