We've been developing a more compressive technical bib short for a few seasons and now they are finally here. For S4's we are using an all-new sublime, power-stretch body fabric with legitimate compression for all-day performance and muscle/body support.  We've paired that with a medium profile women's specific endurance pad, our all-new super breathable technical mesh straps, an ultra-comfort leg gripper, and a streamlined silhouette to make this slickest bib we've ever ridden in.  We've also eliminated all non-essential seams to avoid chaffing, and streamlined our pattern work to make the S4 an anatomic wonder which fits like a glove.  This is our most advanced technical bib to date and they come ready to rock straight out the box. All are Made in New York City. \nDurability: Extremely High\nFabric: Synthetic Blend\nCare: Easy\nFit: Race-Inspired / Compressive / True to Size\nChamois: Women's Specific medium profile / all-day endurance pad\nBest For: All Riding Styles \n\n\n\n ","images":["https://cdn.shopify.com/s/files/1/0143/5202/products/s4-performance-bib-short-1-black_400.jpg?v=1628037785"],"price":150,"currency":"USD","in_stock":true,"inventory_qty":19998,"dynamic_pricing":false,"listed_at":"2026-06-18T20:46:40.245Z"},"share_url":"https://firestarter.network/l/lst_EpxPf0KE","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
