Thank you 2XU! If you haven't tried 2XU technical compression gear, you're missing out. 2XU has been the world leader in performance compression for 20 years, helping runners feel better and recover faster with compression gear that's backed by scientific evidence. Their graduated compression gear is engineered to improve blood flow and performance while speeding recovery. My personal favorites include the Light Speed React half-tights (with tons of pockets for your phone and fuel!) as well as their Ignition Shield tights (for colder weather). But the recovery tights for use after running are more highly graduated and make me feel better after tough runs. 10/10 would recommend! Knowing that their gear is engineered for runners by runners and backed by research makes me absolutely love 2XU.
