Too many characters!

Excellent value and surprisingly great quality!
I popped into Infinity in Farnborough where as expected I received excellent advice and guidance as usual. Great lads that always go the extra mile to assist in every way possible to help you get what you need. These trousers fit amazingly well and the size I went for was a perfect fit. They are very well padded, great comfort feel and ticked all my boxes for a good durable autumn / winter set of trousers. These have a good thermal non removable liner, good zips to help slide over your boots. Two deep enough front pockets which are handy to have. These are very very waterproof and stood up to some heavy prolonged rain which did their job 100%. No leaking in around the usual crotch area like my last pair which were way more expensive in their day. The knee protection is good but hip protection is extra if you want it. Armour pockets are there ready for them when they get them in stock. For £79.99 nothing negative.
