i stumbled on the fact that jackets or hoodies by
www.blueinc.co.uk are excellent for window cleaning. their stuff is expensive but no rubbish is sold by them . mostly their stuff has elasticated cuffs and waists which is a plus point in cleaners clothing
i have a fur lined blue inc hoodie reserved for winter use only, i acquired it secondhand and then paid a seamstress i know to repair it ,worth every penny too , its a cherished item of mine .
