LTDinPNWwrote a review of Mavic Ksyrium Merino Knee Warmer on September 19, 2019
Familiarity: I returned this product before using it
Open disclosure: I'm trying to replace one of my absolute favorite cycling specific items of all time (which are no longer available), Ibex Wool Knee Warmers. This pair from Mavic fall short in every category. They are paper thin - as in wore them sitting in the house, and they barely created more warmth than without. They have zero retention system to keep them in place, which means that with the most subtle movement - they want to fall down. I do understand that they'll be tucked under my riding shorts, but again - compared to my ol' trusty Ibex... they fall short for sure. If you are looking for the ultimate in a minimal design; these might be worth you looking into, but just know a head of time - they really are very very minimal in every regard.
p.s. - if anyone knows where I can pickup a pair of L Ibex Knee Warmers, please feel free to share!!! Thanks!
