Voltaic believes in combining innovative features with a classic design. Their solar bags are mobile solar power generators designed to charge virtually all handheld electronics. Voltaic also uses fabrics made from recycled PET (i.e. soda bottles). They worked extensively with suppliers to develop these fabrics, since they were not previously available, and created a recycled PET fabric that is lightweight, extremely durable, UV resistant and water resistant. It even looks better than the nylon it replaced. Most importantly, it uses significantly less energy to produce and creates demand for recycled materials. Voltaic bags are both eco-friendly and fashionable!
