I work 3 shifts a week in an express store and received one pack (4pc) at the beginning of this month. No tesco branding on them, company on packaging is 'Step Ahead'. Tested to 30 washes, 60degrees, non tumblable. Disappointed that they are just one size fits all, far too loose on me and steam up my glasses. According to the packaging they are 'not classed as PPE'.
