In reply to An Triubhas:
I bought a pair of these, after having used the plain VR trousers for the past 3 winter seasons. So far they've done 2 routes with me in the Norries.
Basically a beefed up version, though the little touches and tweaks make it a far superior pair of troos IMO.
The side zips on the calves mean itll fit round Alpine Touring boots, whereas the plain ones had to go inside the boot.
Under-boot lace means Gaiters are less needed (I dont tend to wear gaiters anyway), but yet to test them out on deep snow or bog, so cant comment on how effective they actually are.
Vents on the thighs are great to prevent overheating on the walk-in, and are surprisingly effective.
All-in-all very chuffed with them, throughly reccommend. Combined with a pair of merino leggings underneath, the old version was all I ever wore for Scottish Winter stuff, dont even pack Goretex troos anymore, as even in very wet conditions, the only time I ever got wet legs was when kneeling in snow, and even then, the VR system dried out extremely quickly once moving again. Cant say the same for the guides, as only had them out a couple times, but reckon theyll perform similarly.
cheers,
