These overshoes give excellent protection from wind and rain, considering their low bulk.
The Pros are made from antibacterial bamboo charcoal fleece with a stretchy polyurethane coating that's described as 'water resistant'. We think the manufacturers are underselling themselves here because no water at all got inside during our wet weather rides.
You don't get quite as much insulation as with a thick neoprene overshoe, but the fabric reaches around to cover most of the sole for extra warmth. The zip pull is held in place by a reflective Velcro cuff strap that also allows you to fine-tune fit, and extensive reflective detailing gets you seen at night.
