For two years,I purchased only CW-X tights. I purchased a pair of 2XU based on internet reviews. They are fantastic ! Bottom line...they give better support. I feel the difference in my knees, and, in my legs overall. I'm 55 y/o and have arthritic knees. Wearing the 2XU tights lets me workout 5-6 days a week ( interval training, weights, Pilates ). Worth the investment !<a data-hook="product-link-linked" class="a-link-normal" href="/2XU-Men-s-Elite-Graduated-Perfomance-Compression-Tights/dp/B0045EP6AQ/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">2XU Men's Elite Graduated Perfomance Compression Tights</a>
