There are "honest" reviews in exchange for free product, and there are reviews written by those who pay for the item...you will be the judge who writes honestly. I review my purchases, and do not owe any favors to seller or manufacturer.

I have bought those pants after reading in some reviews that they might run big. I am 5'11", 182 lbs guy, and medium size pants fit me perfectly. They are made of polyester, with insulation sewn in. Not heavy, very comfortable. Waist can be adjusted (if needed) with attached velcro. Also, there are pant loops that can be used to further ensure fit. Zippered pockets will protect your valuables from slipping out during activities. Inner part of the lower leg is reinforced at the ankles with denier fabric. There is a zipper on outside of the lower leg that allows for taking off ski or snowboard boots. There are no vents, but I do not find it as a negative feature. Those pants are quite warm and wind proof. I am  not sure about their waterproof ability (or lack of thereof) - I simply did not have a chance to test them in that environment.

PROS:
- good fit.
-can be further adjusted with velcro straps if needed, or belt.
-warm
-reinforced inner part of the lower leg
-zipper on the outer side of lower leg allows putting on/taking off boots with ease.
- great price.

CONS:
- can be "noisy" - while walking, when fabric rubs together, it makes noise - but those are not "ninja" pants for stealth excursions....

OVERALL: very good considering features and price. Yes, I would buy them again.
