It's what I wear for my commute. And will carry on with them for at least end of Much unless the weather is exceptionally warm for the time of year.
Like to have warmer knees the older I get.
Thanks Ian, and the others that responded on this, I think I'm coming round to the idea of needing more 3/4 stuff. My knees definitely seem to prefer warmth wheareas my shins/calfs don't seem so bothered. It's starting to feel like the majority of the year would be best suited to 3/4s of varying weights. Leave the shorts for Summer and I have various full length bottoms, waisted, for the odd really cold spell.
By the way can leg warmers be worn over the top of 3/4s if needed to cover the shins?
