The hot grips were a birthday present for my daughter’s friend who I got through her CBT. She is a genuine keen biker who sufferers from Reynard’s Syndrome so gets very cold extremities. Perfect gift I thought from our family to her as she commutes to Truro so genuinely needs them.
A decent set of grips is thems, I used them on my courier bike in 2012, couple them with bar muffs and you don't need gloves even in the coldest crappest weather, but id never advocate riding without wearing gloves
