The Eos UltraLight 2.0 is a 140-gram running vest built for hydration and small-gear carry on training runs and races. It has a zipped phone and card pocket sized for large phones, a zipped shoulder key pocket, a velcro shoulder pouch, a rear velcro mesh pocket for a bottle, and a routed path for a hydration tube. It is designed to fit Eos 500ml and 700ml bladders and is cut for both men and women. Rivals in this class often weigh more or carry fewer dedicated pockets; the trade-off here is a light, close-fitting build rather than a large-capacity pack.

Rated 4.7 out of 5 across 280 ratings, owners largely praise the low weight and the pocket layout. Complaints center on capacity and on the bladder being a separate purchase.
The Eos UltraLight 2.0 Running Vest was designed in Ireland and developed with athlete feedback. It weighs 140 grams and is made for men and women. It can be used for training, racing and everyday running.
The vest is made from mesh for a light feel. It carries water bottles, snacks, gels, keys and other essentials in several pockets and pouches. A designated tube route keeps a water tube in place so hydration stays within reach.
A large velcro mesh pocket on the back holds larger items such as a water bottle. 360° reflective printing adds visibility. All Eos Running Vests fit with the Eos 500ml and 700ml Water Bladders.
