A brief, not-yet-used-them-in-anger appraisal of the RR trousers:
The fabrics differ: the stretch parts of the Nordwand seem significantly tougher than the Silence (which, unlike the Nordwand, is nearly all stretch fabric). The Nordwand seem the heavier-duty of the two and probably the warmer. I went for the Nordwand because the stretch in the backside and knees seemed like it might work for biking if I ever wanted it to, and the Silence because of the waterproof backside, which is always a handy thing on a day walk.
The pockets on both are quite snug, thanks to the tight fit. The leg pockets are on the front of the thigh which feels a bit odd, but won’t be a problem.
Fit felt not quite right at first. My reference point is Next 36×36″ slim fit stretch jeans, which fit me spot on, and I went for the Large in the RRs. They’re very snug around the top end, the Silence a little more so than the Nordwand, but they’re very stretchy; again the Silence a little more so than the Nordwand. Once you’re moving they feel good.
The length is *just* enough. I could use half an inch or so more, but it’s workable: the stretch in both means that the ankles don’t pull up even when crouching. Also I don’t currently have high-top boots, which doesn’t help.
The boot hooks on the front of the hem seem to work well enough, as do the poppers. These are the reason I chose the “Pro” versions of the trousers, as the non-Pro have velcro. The Pro also have ventilation zips in the thigh but I’m not bothered about these.
Overall I think they’ll do nicely, especially at the Black Friday prices. I’ve got a weekend coming up which will involve a day in cold and exposed terrain and another in sheltered but wet terrain and each of them has basically slotted nicely into being ideal for one of those days.
