Giro Me2 here, which suited both ours, but was a bit small for a friend’s 2 year old.
Youngest has moved onto a Uvex Hero – lovely helmets and fits him well (he’s on his second having written one off), but as said I think their basic shape is quite different to some other makes.
We’ve been lucky – bought online and they’ve fitted fine. The difficulty at that age is getting them something, them trying it, and then you having to wrench it off them to send back as it’s the wrong size. Never went down well with our two! So shop trying is probably best if you can do it 😉
I bought a specialized for my little one. I measured his head and found that a lot of hats only went up to that size and then jumped to a much large size bracket. The spesh had a size range that spanned the gap in other makes. It fits perfect and has plenty of space to grow yet. I can’t remember off the top if my head the model but there was lots of colour and design variations.
My Son has just gone from a Samll Fry up to a MET Genio – its got a cool little LED on the twist fastner thing. Need to go and get the Daughter a new one as well..
We tried Hatter Jr on a Giro at first, he hated is so much he actually tore clumps of his own hair out trying to get it off when he was sat in the Chariot. Also tried Specialized, similar reaction.
At around 20 months we finally tried a Lazer P’nut and it was like night and day, he happily walks round the house in it. Great little lid, the retention system and padding is streets ahead of what you usually get on kids stuff.
My only regret is that we didn’t get the MIPS version, when he outgrows this one we’ll be getting him the bigger version with MIPS.
If budget is a concern I’d say MET but if you don’t mind paying £35+ for a kids lid then Lazer all the way.
