THE MATERIAL THAT PROTECTS BUILDINGS FROM WIND AND RAIN NOW DRESSES YOU

Tyvek resembles crumpled tissue paper (the type used at stores, not the sort for blowing your nose), feels like plastic, and is a kind of plastic – flash-spun high-density polyethylene fibres, to be exact. Seen more at construction sites than on clothing racks, the recyclable material is extremely lightweight yet highly durable, washable yet water-resistant, tearand fray-proof but possible to cut to size, and resistant to mildew and chemical agents. Fyber Forma – available at Actually (#03-18 Orchard Gateway) – reimagines it for bomber jackets and everyday bags (backpacks, shoppers, totes) so they can take a beating when you need them to.
