Leather, nakedness and commuting

[Dead Eye]

The reason for jeans is that out of all the standard items of clothing for your legs, they offer the most protection - its not great protection, but its a bit better. Jog bottoms, suit trousers, shorts and many other forms will completely disintegrate and a lot of artificial materials will melt to your skin under high temperatures. A decent pair of jeans (not the £5 crap) will drag a bit, albeit not particularly far and despite offering no real protection against crushing / burning at least they won't melt on to you

At the end of the day though, they are still a last resort and offer pretty poor protection compared to proper attire
