I wear my new helmet Alpina Panoma for some time now and am very satisfied. Have a small head and a few helmets tried. This fits now, can be adapted well. Even with cap underneath. The straps around the ears can be adjusted well, that's important to me. Did not go so well for other models. And the chin buckle is great with the new system, so nee way "ratchet". So that I can adjust the straps in length by "pressing a button" under the chin. Without equal to solve the whole buckle and rumzufummeln in any bands! That's really good invention nee !!
