The pinnacle of SOAR garment technology, the life of Nano Rain Jacket began with a diligent study to create a brand new material, capable of taking effectiveness in wet weather to the extremes. This custom membraned fabric has all the stats that translate into superlative functional breathability and waterproofness - and then some. Nano-sized perforations on the internal membrane let you run at your maximum without building up moisture levels inside, while externally, our proven twofold DWR application – one at yarn level and one at fabric level – works to ensure waterproofness, guaranteeing unrivalled water run-off over the long-term.

From here, we got prescriptive with the details of the jacket's construction and functionality, ensuring an ultra-durable exterior for use with a backpack and practical design details that include stretch cuffs for comfort, a drawstring trim to block out the cold or increase air flow, high-vis detailing for visibility in low light and a rear pocket for on-run essentials. 

As a flagship piece in the UTR collection, fully taped seams and a hood are non-negotiables. Providing the requisite protection without limiting your vision, the ergonomic, pre-tensioned hood comes with a single-pull back adjuster for comfort and a nifty popper to trap it down in the dry. Rest assured, race directors will only pick you and the Nano out for good reasons.

Streamlined for use on the road or trails, exposed high-altitude ridgelines or wet canal paths, we can talk about the tech of Nano Rain Jacket until we’re short of breath, but nothing beats real-world application.
