Like all protective gear, glasses and hats are no good at all when they're in your bag, so the No1 requirement is that they are comfortable enough that you won't be tempted to take them off.
Steel toecap boots can be made more comfortable with thick woolen socks and Sorbothane sole inserts, these really take the shock out, especially if you're carrying something heavy. I favour wrap around glasses from Dickies (
http://www.dickiesstore.co.uk/dickies-wo...8209#Smoke ) which are about £8 a pair in Jewsons, they don't steam up or cut into my face and the arms grip snugly which keeps them in place all the time without the need for a back strap. My bump cap is from B&Q, I like it, but it does have a reflective strip sewn in which might not be appropriate in all situations (

I find them much better than the cheap "rigger" gloves, which don't last and are too loose anyway. I keep them supple with neatsfoot oil. Another type I like are the thick leather chainsaw gloves with nylon backs, they are supple and have elasticated wrists to keep them in place, but are usually fluorescent orange which might be a problem.
Charles, those trousers look excellent, I try to find a UK supplier.
Found the gloves on the DeWalt site. I see they also do a goatskin version, I think I'll try to get a pair of those.
