Hi, I would say that piss pots (aka skin lids.) are a tad too heavy for Trials biking. As now I can say because I have used both types of helmets. 1. Piss pots 2.Giro etc... Like some people say the piss pots cover up most of your head, However they are a little too heavy for my likings. I rode with a TSG helmet which was a piss pot, Which cost me £20 But these are quite heavy. Also after breaking that, I then bought a Giro Hex, good for the money only £50 in my local bike shop. Also after breaking that one, I then bought a Giro Xen. These are a little too much but much stronger than the Hex. Costing me £90 for the Xen. Fallen off a few times with this and wacked my head and it's still in good nikk, and working fine. Hope I have helped Thanks Ross. P.S.The helmet does look rather nice you have pointed out though.
