Clothing is confusing

Armoured over trousers

Something like these with thermal liner removed so your jeans act as the liner? Halvarssons W Pant Waterproof Textile Trousers Black Hi-Art CE Level 2 Armour ETA just seen your budget; but I picked a pair of Halvarssons trousers up a year or two ago in the sale for around the budget you have so it may be worth hunting around for sales once you see something you like.

This thread might be of some help.
