OiOi retro Sherpa messenger bag
Although there's nothing particularly retro about the shape of this bag, the 70s-inspired material used for the OiOi Sherpa messenger bag certainly qualifies it for the tag.
There's actually two patterns available, both in designs that would fit into any 70s living room. The bag itself is actually made of a water resistant micro fibre, has separate internal pockets, outer zip pockets for your phone and music player, an insulated bottle holder and two exterior insulated side pockets.
Available from the US for $70, which is around £40.
