You guys are the best and helped me a lot in understanding Kevlar lined jeans and other fabric Cordura and their comparison with respect to leather.
I was able to find a store that I visited. They had 3 brands of such jeans - DRAYKO, DRAGGIN and SPEED-&-STRENGTH jeans. All of them were in the price range of $100 to $150.
DRAYKO - Designed in Australia (Made in China) - Very well designed, Good cloth, comfortable to wear, fit well.
Kevlar lined at the rear, front/sides knees and sides of legs. No pockets for pads or armor. They get 4*/5.
DRAGGIN - Designed in US (Made in US) - Good cloth, comfortable, fit well, deep pockets, good color.
This jean has the least amount of Kevlar coverage - only on rear and front of knees. No pockets for pads or armor. Though the company sells pads with Velcro that can be attached to Kevlar
. Not well designed. They get 3*/5.
SPEED/STRENGTH - (Made in Pakistan). They have Kevlar linning for rear and front of knees and also cloth pocket for thin knee pad - Idea is good but I was not impressed by quality and reliability. They get 3*/5.
HOOD - (Designed and Made in UK). The store did NOT have these jeans. But WillW and fxrskrsa have given very good opinion on them. I looked at their website (thanks WillW) and am very impressed.
They have the best design and most coverage for entire leg !! They get 5*/5.
I took some pictures of DRAGGIN jeans - front and back.
