Trendy. Trendier! Trendiest! The ZIPPER is delightfully retro. This striking backpack with its diagonal zip would go perfectly with a 1980s-style body warmer and raincoat in contrasting colours. The bag is unicolour, and the cheeky diagonal zip a bit more colourful. You can't tell by looking, but the ZIPPER is made from recycled soft drink bottles. So it's environmentally friendly too. The matt exterior gives the bag a chic yet sturdy character. The hand and shoulder straps are made from polyester but are as flexible as cotton. The bag itself is available in a range of unicolours. There are multi-coloured zips on the front and top of the bag.
