some ideas
1. (practical) paraffin coated 634-XHS
2. (tough and unchanging) superblack, paraffin coated 634-XHS
3. (crazy warm winter/ski jeans) paraffin coated, flannel lined 634-XHS
4. (crazy tough) paraffin coated, double knee XHS 634
5. (summer rain XHS) paraffin coated, extra loose weave for more breathability (would be great for really hot/humid countries that have wet and dry seasons.
6. (full armour combo) paraffin coated, reenforced at hemmed area with a way to 'lock' or 'button' into shoes (also waterproofed) which come with the jeans. it would be a set up to almost fully water proof the jeans and shoes connection area.
I like fades and hot weather so no. 1. and no. 6. would be my favs.
I'd like to see motorcycle jeans with pockets for armour and either leather or kevlar lining, or kevlar denim mix.
