The Stoke Jacket Shell. The best just got better. From athlete feedback and field tester's input, we improved this jacket and bib combo with an improved 5TECH Pro stretch material. Alpine proven materials with 20k/20k performance, now with a stretch woven construction. The stretch woven has 3% stretch, which provides a bit of ease, improves fit, comfort, and reduces seam stress. Built with our new 3-layer construction, we removed the taffeta lining for optimal fit and finish. Other improvements in the pocket layout for the alpine environment and use with an Any pack. Product does not include any biproduct of Sharks.
