Tights

I do the fleece bibs + optional kneewarmers thing. Bibknicks are a lottery - the way the knee joint is stitched and designed to articulate is based on having a certain femur length. If you happen to not fit this template, despite them being the correct size, you end up with them riding up, or stitching cutting across tendons at uncomfortable places, and so on. The 2-part system gets around this predicament.

This is a bit of a worry for me. I carry most of my shortness in my femurs. I shall look into thermal bibs some more, before committing. Either way I can see myself covering my knees up all year. I think my cold weather running has aged them beyond their already advanced years.

Cheers for the advice.
