The Ultrapant is an ultra lightweight, waterproof, breathable running pant made from a 2.5 layer transparent fabric. Fulfills race criteria when mandatory kit requires waterproofs with taped seams.
Our lightest waterproof running trouser has been stripped back even further and now weighs just 86g. Designed for those runners wanting to race as light and fast as possible, this breathable trouser is perfect mandatory race-day kit. Packs away small for easy, lightweight carrying.
The Ultrapant Waterproof Overtrousers are the lightest waterproof trouser Inov8 have ever produced and they are the ideal piece of kit for mountain and ultra athletes who want to race as light and fast as possible. The key feature of these pants is the transparent 2.5 layer, 4-way stretch fabric that can easily stretch to fit over your trail shoes.
As well as being super lightweight, they pack down really small and can be secured in place using an integrated loop on the waistband, making them easy to carry. The trouser also features taped seams, an elasticated front, waistband and hem and a reflective logo for better visibility. They are never going to be the most durable waterproofs at this weight but I wouldn't have anything else in my pack for races as for how often I actually need or want to wear them there is no point carrying heavier, more durable alternatives.
