I've lost count of the number of times I've nipped into the workshop or garden to do a quick job without getting changed - and ended up knackering an item of clothing.
Aprons help a lot with that. There's one hanging on the door into the workshop and I try and discipline myself to stick it on as a walk in.
If you are looking for a heavy duty apron then the Carhartt Duck aprons are some of the toughest we've seen. Made from 12 oz duck canvas they are stiff to start with. Unfortunately Carhartt are having some stock issues at the moment and supply is difficult.
If you are looking for a lighter weight apron with less pockets then we've just started to stock Risdon & Risdon - who's Studio Apron are great for more general use.
