So popped out to argos to pick one up at lunchtime (only 1 store had 1 in stock, so thought i'd best be quick) was a bit worried about sizing as my strangely shaped bonce means i usually hit xl or xxl to get my head into the helmet, rather than the helmet on my head comedy stylee......but it fits perfectly
reminds me of a skate helmet i had when i was a kid
the only downside thus far is the weight, its comparable in weight to my troy lee full face downhill helmet, though not uncomfortable to wear as weight is distributed well, and i like the neck brace feel at the back, suspect it will stop my head wobbling on way home from the pub
thanks again for the reccomendation!!
