We’ve given our popular men’s jammer an update using our super-durable ECO Endurance+ fabric. Retaining the streamlined cut, integral support and drawstring waist that make it so comfy during training, it's quick to dry and 100% chlorine resistant, making it ideal for regular training sessions. Newly updated, one of the yarns in this fabric is made from 100% post-consumer waste, such as recycled plastic bottles.
