Arc'teryx Alpha LT 1/2 Bib Pant - Men's

It's not a burly bib, it's not a simple pant cut that would get all the snow into your thermals after an embarrassing moment on the powder.
Proper disclosure: used it only for ski touring/resort skiing and not for climbing (yet).
However the 1/2 bib feels rather "technical", I don't get much bulk. I wear a small (5'9", 145lb) and it's perfect.
The good:
* High enough to keep the snow out, not too high to make it uncomfortable.
* The reinforcements in the lower parts of the pants definitely protects against skis cutting your pants, however I'm not sure about crampons.
* Zippers go all the way up for good ventilation
* Altogether a really nice pair of pants for skiing (and probably also climbing), it doesn't feel cheap, the opposite actually, it's Arc'teryx after all
* Pretty lightweight I would say, packs nicely

OK, the good stuff, or actually - the bad - this is usually what I like to hear about gear:
* NO POCKETS - Why? - no idea. A little pocket on each side could have made it a bit nicer. Where am I supposed to put my phone while I'm BC skiing? (can't use the jacket pockets as they would interfere with the transceiver).
* Suspenders suck - they are not really detachable. If you need to go for a number 2, you'll have to supposedly strip down to your thermal shirt, pull down the suspenders, take a number 2, then do everything in the reverse order. Or perhaps maybe I'm missing something. In my old pants my suspenders could have stayed on me, could detach them from the pants - and pull the pants down. Not here - or maybe I'm missing something but I don't believe so.
* Black black black - I'm tired of stuff in the color of black. I don't need a zebra/tiger sample on my pants, but red/blue/green would have been much nicer than the boring black.
* PRICE - wooohoo, it's $450 for the retail, if you can get it for $350 then it's OK, if it's anymore than that - it's a ripoff in my opinion. It's a good pair of pants, but you don't need to take a mortgage for it.

So it gets 3 stars, mainly because it's not perfect (-1) and the price is ultra high (-1). The rest is perfect and I'm enjoying it.

It is very difficult to find shell pants that have Full zips on the sides. (Full... from top to bottom). These come in handy when it is just blowing sideways, and you are working hard. You want the full protection but also want ventilation.
I had an older pair of marmot precip rain pants that had this feature, but finally destroyed them on a glissade.
The alpha lt pants are the pants I have been looking for. Light, yet extremely durable. Gore pro shell is not quite as breathable as eVent, but for bottoms they work great. oh... and for those who care... these are MADE IN CANADA.

Everything, but the suspenders are amazing. I like the 1/2 bib feature for keeping out snow, but the suspender design doesn't work so well in my mind. I really wish Arcterx would only use one kind of suspender so you only had to carry 1 set up a mountain. Going to try and modify the pants.

We bought the pants for alpine climbing and used them two weeks ago on Mt Shuksan, Washington. The full size zips allow for easy on and off, even with crampons, and the suspenders were very comfortable. We saw a wide range of temperaturers and the pants were perfect.

I wanted tough, totally waterproof ski pants. These have measured up. They have taken some tree abuse and have kept me totally dry in a lot of wet snow (happily, no rain yet, but I am confident they would keep that out as well). They aren't insulated, but offer a perfect wind barrier, so all I have to do is wear underwear that is warm enough for the day's weather. I am 5'9", 160 lbs. and get a good fit from a medium. Powder cuffs fit snugly but comfortably over ski boots. The 2 pockets are reasonably good sized, though I wish the pants had one in the rear. I expect I will get years of good service from these pants.
