Image 2 of 5 from Fold-up sports helmet easy to stash

September 18, 2007 Bicycle helmets might be light, but they’re still very annoying to carry around because of their awkward shape. Stashkit have taken aim at this problem by producing a fold-up helmet that offers all the protection of a regular lid, but stows away much more easily. It’s the perfect companion for a fold-up bicycle.
