Visible & warm

Got these leg warmers on sale because I wanted to wear something more visible than black leg warmers during my pre-dawn rides through Toronto. Since the temperature has gone down this week to about 34 F, I also wanted something warm. These Castelli leg wamers fit the bill, on both counts. They fit well (I ordered Large), they stay in place over the course of a one-hour ride, the zippered ankles make them easy to put on and take off, and although I've never driven up behind myself in a car, I suspect that drivers can see them from a reasonably long distance.


Very warm and 100% waterproof. They are truly unbelievable! The fit is not designed for someone like me though; They are too long and if I went a size down they would be too tight. Still great though!

Essential for my night time commute on dark winter nights


Added visibility on dark nights
Highly water resistant (water beads off
Zipper on back is useful for getting on and off.
Versatility when combined with the Nanoflex Claudio shorts by Castelli.

Will collect dirt (don't mind cleaning them -esp if they help keep me visible)
Some people may not like the style.

I have 2 sets of these now - very happy

Watch your sizing - go 1 size up.
