Rated 5 out of 5 by from Just what you need Top trousers, comfatable, hard wearing with plenty of pockets for all the bits and pieces you need to do the job. Well worth the money, i'd recommend to any workman, any trade.

Rated 5 out of 5 by from Site Mastiff Trousers Very impressed with these trousers so far, as only just bought them, hence why i've only scored them a 4 for reliability! Always buy snickers but fed up paying a fortune for work trousers, so i thought i would give them a go! Got a size bigger, as i prefer a bit more room & leg length is longer than stated? Plus got them on sale for £25, bargain!!

Rated 4 out of 5 by from Work Trousers Excellent product for using when doing underfloor heating. Bought knee pad inserts which were so much easier to fit than my old pair due to velcro top opening on trousers.

Rated 4 out of 5 by from Sizing These seem like good trousers but who on earth signed off the sizing measurements? They are rediculously over sized. Sort it out!
