Super handy winter accessory
Keeps my head and esp. my ears cozy warm all winter long, so much more convenient that donning and doffing another layer each time I get on and off my bike.

Sufficiently warm for New England winters.
It’s a perfect fit for my Lumos Kickstart helmet too. It’s nice to see that it was designed with a discontinued model in mind, since replacing my old helmet isn’t something I’m planning on doing right now. It’s nice to know that it’ll work with the newer helmets too though, since replacing my old one is something I know I’ll have to do eventually.
