The svalbard heavy duty hybrid pant presents a good balance of style, functionality, and toughness.
I bought this pant primarily as my bushcraft/survial training pant during the colder season and here are couple of pros and cons based on 4 days of heavy duty use laying on the ground on my butt, knees, and bushwhacking through thick woods with thorns all over the place.
1. This is one of the better looking pants in its class, and the attached waist band allows you to get a near custom fit. My waist is between 32~33" with inseem of ~31" and the medium fit me almost perfectly (the leg is slightly longer than I'd like).
2. Six zippered pockets are very useful for variety of uses, and the side vent is very useful when it gets a little hot during the day.
3. The fabric keeps you plenty warm. I've worn it down to low 30s without any base layer and my legs felt fine.
4. The fabric is pretty tough, after 2 to 3 days of bushwhacking through thorny vines, I only saw maybe 4 or 5 spots where threads came loose near on the legs.
1. Contrary to the pictures shown, the cargo pocket zippers (and the back pocket zippers, although these aren't pictured) do not have string pull tabs that the hand pockets have. The actual zipper tabs are pretty small, so if you have extra large (and sometimes clumsy in the cold hands like me), then it's not always pleasant to use the zippers.
2. These pants are made in Vietnam. Don't know whether that's the reason, but the fit/finish don't seem as good as my Lofoten pro shell pant which is made in China.
3. The Flex3 softshell in the seat and knees will soak through if laying on damp ground for couple of minutes.
If I had much longer legs, I'd go for a Fjallraven pant as I think they're better suited for my uses, but I don't think you can go wrong with the Svalbard pant as an all-around outdoor pant for colder seasons.
