The Montane Minimus Nano Pull-Over Waterproof Pants are built for runners who demand the lightest possible kit without compromising on performance. Designed for fast-and-light racing and training, these trousers weigh just 100g (size medium), making them one of the lightest waterproof running trousers available. They pack down into their own compact stuff sac, taking up barely any space in your running vest or race pack.

The 20D fabric is specifically designed for endurance events and ultra marathons, offering reliable protection when you need it without adding unnecessary weight.
