California Residents: Prior to December 2023 the trim material used on the Tri-Fold lid and RUX Pocket liner had a short chain c6 DWR coating, made with PFAS chemicals. Once RUX learn learned this coating was being used it was switched for all future production and all RUX products are free from intentionally added PFAS.
