I have two Rab garments in eVent (the Latok Alpine pants and the heavy duty Latok jacket), several pairs of Rab gloves, and a Rab down bag.
The eVent items from Rab are good utilitarian kit, but not worldbeaters. The advantages of eVent are well-known, but there is a problem that I'll get to in a moment. The Latok Alpine pants are somewhat odd in that the side zippers don't go all the way to the waist, which makes it impossible to put them on when wearing skis–or to get to the pockets in your under layer. Of course, this design is done so that a pack's hip belt won't chafe against the zipper, and many Arc'teryx shell pants are also made this way. And somewhat suprisingly for mountaineering-oriented trousers, there are belt loops.
The best thing about the parka is the wired hood–it really does work. But other than the eVent and the water-resistant zippers, there's nothing in the design of this jacket that hadn't been done in 1995 or earlier. And the qaulity of construction of the Rab jacket is not on the same level as Patagonia or Arc'teryx–the seam taping is wide and not all that straight, the stitching isn't anything special, the mesh interior pockets are indifferently fitted, etc. For an example of a really well made bomber winter shell, look at Patagonia's Stretch Element with its seam welded construction and great fabric. I'm not saying that the Latok will fall apart, just that other companies pay greater attention to details.
My two complaints with eVent are that the material is not entirely windproof (noticeable only when skiing fast) and that the inner scrim is far less durable than what is used on Gore or Patagonia H2No garments. That light grey stuff used with eVent is extremely easy to snag or abrade. I don't know how this durability problem qffects the waterproofing and/or protection of the membrane, but it is there.
I also had an eVent tent from Nemo that had the seam tape separate from the material after only one rainy night, but so far I haven't seen this happen with any Event garments (I also have pants and a jacket from Lowe Alpine and the famous $50 Teva jacket).
The Rab gloves are fine (they are one of the few companies that make non-waterproof softshell gloves with leather palms) but the sleeping bag (a 0F or so mummy with a Pertex Endurance shell) is a disappointment–crooked stitching, skimpy draft collar, not as much loft as you'd expect for the temperature rating. I'd say it's about at the level of TNF or Kelty in quality–definitely below Marmot, and certainly no match for Valandre, Integral Designs, Western Mountaineering or Feathered Friends.
