What kind of helmet are y'all wearing? I've been using this open Face from the start, but it's getting soooo cold now and it's a struggle with streaming eyes 😂 I need something with a visor, but not too heavy, of course.

Get a motorcycle balaclava. I have one of those under a similar, but even more ventilated, full face and it's nice and toasty now. Also decent goggles help. I wouldn't wear sunglasses at all. I had a cut out and the worst injury was the arm of the sunglasses broke and cut my eyebrow quite deeply. A few mm lower could have been really bad.

Bell Super 3R MIPS and taped the vents for winter riding. And sometimes my skihelmet. While walking the dog the Xiaomi helmet with LED-Backlight ... easy to get my fingers in my mouth for a loud whisle

I use a Kali: https://www.speedyfeet.co.uk/collections/electric-unicycle-protective-wear-helmets/products/full-face-mountain-bike-helmet-alpine-carbon81

And for the cold weather rides I wear MX goggles like these: https://www.speedyfeet.co.uk/collections/electric-unicycle-protective-wear-helmets/goggles31
