What Our Gearhead(R) Experts Are Saying:"I wore these through a hot summer training block and never had to think about them shifting mid stride. The thigh pocket held my phone through a full tempo run without any bounce."Hot weather training goes better in the Ad-Vantage 4in Shorts, and Outdoor Research built them to keep pace no matter how hard the session gets. The high waisted, elastic fit stays put through intervals and long tempo miles alike, so the only thing you're thinking about is your next split. DuraPrint reinforcement along the sides adds durability exactly where repetitive motion wears fabric down fastest, while the recycled polyester and spandex blend moves with you instead of against you. Two front pockets plus a drop in thigh pocket mean keys, gels, or a phone all have somewhere to go, no armband required.
