The PAS Mechanism Long Sleeve Jersey is suitable for layering or as a standalone jersey. All through the seasons. The PAS Mechanism Long Sleeve Jersey exhibits the Pas Normal Studios mentality of seamlessly combining visual aesthetics with quality, technical apparel. The soft fleece-backed fabric makes the PAS Mechanism Long Sleeve Jersey perfect for both high-intensity training and racing. Use it as a standalone outer layer on chill mornings or late afternoons. Or pair it with a heavier base layer and a gilet or jacket when the temperature drops.
