I have a pair of Bullitt and a pair of Spidi jeans. The Bullitt cost about £80 w’out armour and are lined with Covec, a Kevlar type material. They’re comfortable but still quite hot when the temp is hot & sunny so suitable for spring, autumn, winter. The Spidi cost 150 but are single layer having the Kevlar type threads woven into the denim plus their specific armour is better fitting. They look and wear like a normal jean and are great in summer. Just FYI
