Polypropylene coverall with zipped front, hood, and elasticised wrist and ankle cuffs. These coveralls do a great job of either keeping clothing clean in dusty/dirty environments or stopping contamination of products from dirt that may be carried on clothing. Light weight and breathable. Many businesses buy these as it works out cheaper than buying overalls, paying to get them washed daily and regularly replacing them. Customers of ours that use them extensively include demolition and fibreglass fabrication businesses.
Only in white but they can easily be dyed if you need other colours. You can buy the dyes cheaply at the supermarket or most pharmacies.
Sizes from M to 3XL. It is always better to buy a bigger size in these as they are not meant to be tight fitting. I would go 1 size up at least. The elastic around the ankles and wrists mean that the extra size is not a hazard. Many of our customers just buy 1 size - 3XL!
