The Pinnacle series vests are designed to be 20% lighter and more breathable than the Krar and Howe vests, and have new, thoughtful storage solutions. We train so we can get better, so on race day we will be at our best. No matter how fast or far you are running, this vest is built to keep you at the top of your game. We are excited to see 4L and 12L Pinnacle vests on race day! The Pinnacle series fits like apparel and feels like a second skin, hugging your body and eliminating bound or chaffing.
