Mechanics and workshop staff have a clothing problem most trades do not: everything you wear gets oil, grease and brake dust on it, and it does not come out. That single fact is why this range is built around coveralls and overalls rather than a shirt-and-pant combination — a coverall is the cheapest way to keep one set of clothes ruined instead of all of them.
This is a deliberately small, focused selection rather than a broad catalogue. Coveralls and overalls lead it, with hi vis running through most of the range for workshop traffic, roadside assistance and anyone working in a yard where vehicles are moving. Knee reinforcement appears throughout, which matters for anyone who spends time on a workshop floor or working low on a vehicle. There is a run of flame resistant options for welding, fabrication and hot work, which is common in heavier automotive and truck workshops.
Two practical notes. Sizing a coverall is not the same as sizing a shirt — go by chest and inside leg on the size guide rather than your usual shirt size, particularly if you are wearing layers underneath in winter. And if you are doing fuel system, LPG or battery work, the flame resistance requirement comes from your workshop's own risk assessment; check the rating on the product page rather than assuming a heavy fabric is equivalent.
