The Montane Unisex Minimus Nano Pull On Waterproof Jacket is a market-leading, ultra-lightweight waterproof shell , developed for trail running, racing and fastpacking in challenging mountain environments where every gram counts. Weighing in at around 100-110 grams (size M) , this is one of the lightest fully waterproof garments in its class , designed to be worn at all times – but barely noticeable – until the weather turns.

The jacket is built with PETRICHOR TECHNOLOGY™ 2.5-layer membrane , an extremely thin and durable PU laminate that provides full waterproof protection (15,000 mm water column) combined with high breathability (15,000 g/m²/24 h MVTR) . The 20D tricot surface together with internal mesh print protects the membrane and maintains comfort even directly against the skin. Everything is treated with PFC-free (PFAS-free) DWR for a more sustainable choice.

The minimalist design is completely focused on function at high speeds. A half-length YKK AquaGuard® zipper makes it quick to put on and take off without compromising packability. The PIVOT 0 hood has an elasticated edge and rigid peak that stays stable in wind and rain without the need for adjustment cords - perfect under a cap or running vest. Elasticated cuffs and hem seal out the elements.

Designed specifically to withstand the rigors of ultra-marathon competition and mandatory gear, the Minimus Nano packs down to the size of a palm in a vest or pocket. It's not designed for heavy backpacking, but is great for emergencies, competitions, and fast-paced alpine adventures where protection needs to be deployed quickly.
