Montane Slipstream jacket

The Montane Men's Slipstream Jacket is the most lightweight weather-resistant jacket in the world.
 
The Slipstream is highly functional weather-protective clothing, which is ultra-lightweight and ultra-simple thanks to having minimal seams and using Pertex Quantum fabrics.
 
The Montane Slipstream offers weather protection and breathability in a package of less than 100 grams (including the stuff sac) and is suited to high-energy running and biking for prolonged periods when ultra-low weight is absolutely critical.
