The bottle has a retro-modern feel and the brushed steel is complimented by the vegan leather strap. Unlike most water bottles on the market, this design has only a hint of colour through the silicone seal and ring to hold the strap. The designers did this on purpose to consciously try to not make it a fashion item, but more a utility possession that is appreciated and enjoyed because of its practicality. The bottle might scratch, dent or develop patina from handling, but this will only adds to the charm and value of the design.
