Not exactly a huge black friday deal but it may help someone.
Was in screwfix today for some other bits and saw these on offer.
Bought a pair last year and have lasted really well (longer than I thought TBH after reading some of the reviews) I put dubbin on mine prior to 1st use and keep them pretty clean and occasionally put some more dubbin on. Still in good shape and still waterproof. A bargain at £20 I think.
This was posted over a year ago but was exipred so I thought it may be of interest to some.
They had the tan colour too.
