Mountaineering/ Alpine Pants

I have been looking to get into ice climbing and mountaineering and have most everything except pants, looking around there are a ton of products available. Do you guys have a favorite pair of pants? Previous topics have listed a lot of pants that are no longer sold unfortunately. 

Try out a bunch of brands (Rab, Patagonia, Eddie Bauer FA, Mammut, Marmot, OR, Arcteryx, MH, BD, Millet, etc. - whatever you can get your hands on). They all make great stuff but fit differently, so everyone's preference is likely tied to body size/shape. Summer's the perfect time to do this since everything is cheap.

I love the Rab Torque pants for spring and summer and the OR Cirque for colder conditions

Patagonia Kniferidge or Arc'teryx Psiphon AR when it's chilly. Rab Torque or Arc'teryx Gamma Rock when it's warm. Patagonia and Arc'teryx technical pants tend to run at least half a size big. I'm 5'10, 175-180 lbs with a 31-32 waist, and typically wear medium in everything, but I wear a small in Arc and Patagonia pants. I do prefer a trim fit.

Rab Torque pants are super nice: good features and decent durability. The awesome cordura-like patches are great for scrubbing on awkward rock, and they're a relative deal at $135 retail. My mediums weigh 10.9 oz

+1 on the OR Cirque, love 'for anything mountaineering or ice climbing. 

OR Cirque has treated me very well.  

Love my OR cirques

You do NOT need them just to get out on the ice. It's an expensive hobby and the money would be better spent elsewhere IMO.
