The EQUIPE RS Spring Fall Bib Tights S11 EVO hide a stormproof panel called flakFoil behind the left bib strap, ready to deploy across the chest the moment the weather turns. It stows away just as easily when the sky clears, so there's no separate vest or jacket taking up pocket space for a threat that might not come. A softshell panel at the crotch protects the core from windchill and road spray on its own, and the antimicrobial insert stays shielded behind that panel for dry, breathable comfort through variable spring and fall conditions. What Our Gearhead(R) Experts Are Saying:"I felt the temperature drop on a descent, pulled the flakFoil out from behind my strap, and had it across my chest before I finished the turn. That's a shell vest's job done without a shell vest taking up the pocket."
