The Stratus umbrella collection features a modular system of interchangeable handle components and mechanical functions. A trilobe profile forms the basis for the frame components. This shape increases torsional strength within the telescopic shaft and prevents twisting of the frame and canopy. The umbrella canopy uses 50 per cent recycled polypropylene blended with microfibre. Performance materials, such as aircraft aluminum and carbon fibre within the frame assure longevity and durability. Leather, cork, woods and quality plastics make up the handle pallet options.
