Of the top of my head I can't think of many reviews but if the number of climbers using them are anything to go by then the Petzl Meateor 3+ is the one to get if it fits you and your needs.
I got one as a summer helmet but now use it year round due to the comfort of it. Much nicer to wear all day compared to my 'hardshell' one. It's light weighing in at around 235gms.
It's triple rated for mountaineering, cycling and paddling upto g4.
Head torch clips on it are decent and hold mine in place really well, just a bit fiddly with big gloves on.
Only downside is it's not as squishproof inside my rucksack if it's being chucked around at airports or being sat on etc.
