The JERSEY SEEK AMP SS from Ion is a short sleeve jersey for men made for mountain biking.
It's lightweight, fluid, and breathable, and it dries quickly because it's made from a soft DriRelease Eco fabric of recycled polyester and organic cotton that feels soft to the touch and dries 4 times faster than regular cotton. The relaxed fit ensures ease of movement, while a small pocket is placed in the back.
This model even adds a microfiber eyewear fabric that allows for perfect cleaning of sunglasses or goggles.
