The Evolve Superwarm Double sleeping bas is from our new Earth Collection and is made from a recycled fabric with stylish embossed design, made from 100% recycled single use plastics. The recycled fabric is resilient, whilst being soft to touch. The Vango Evolve is the perfect companion to cuddle up in for a great night's sleep. Stay warm while helping the environment with the filling, shell and lining all made from recycled single use plastics, without compromising on warmth or comfort. Double layer construction creates an open structure that retains heat in the bag, while the integrated head rest provides additional comfort and warmth.
