Waterproof without weight.

Developed for alpine climbing, the Mountain Hardwear Men's Quasar Lite II Pant shields you from weather, packs small, and doesn't weigh you down on the long approach. Its Dry.Q Elite laminate ensures reliable waterproofing as well as a heavy dose of breathability that's air permeable to breathe the moment you put the pant on, unlike most breathable garments that only breathe until after you started sweating. A 2.5-layer makes this pant remarkably thin and light for easy packing. The full side zip helps you put this pant on with your backpack if it starts raining on the approach, and it doubles as ventilators when you need more air. There are adjustments at the waist and cuffs to fit under harnesses and over alpine boots.

Light and Packable

  • Familiarity: I've used it several times
  • Fit: True to size
  • Size Bought: Medium

It's everything I want in an alpine shell pant. It's super light and packable, has full side zips and the insteps are reinforced. I really appreciate the belt and they wear well with a harness. I'm a 32X32 and these fit great over my hiking pants or shorts in a size medium.

Sizing is off

  • Fit: Runs small
  • Size Bought: medium and a large

I purchased a medium and it way too tight in the waist and really everywhere else to be worn as a shell pant, there is no way it would fit over another pant.

I am a medium in any pant I own, between a 33 and a 34 waist.

I purchased a large and that actually fits like what fairly slim medium shell pant should fit like. I would tell most people to size up.

What I like about the pants.. The full side zips and the lightweight stretchiness of the fabric. I had purchased some bomb proof Arcteryx shells a few years ago, but they are so much bulkier than the lightweight shells I have purchased from Mountain Hardwear in their Quasar line. These pants will match up with the lightweight shell and be half as much weight and bulk as the others.

I don't find I use my shells, if I think I am going to be getting dumped on I might bring the bulkier items, for just lugging something along for a what if situation.. These shells from MH are perfect.

The review below where the guy is glissading in them and scrambling through rock? There are better pants for that purpose. For a shell for mountaineering , or for hiking when you are unsure of what the weather might be like while out on the trail? This pant is what I would suggest. For skiing, or for any activity where you know you are going to need more durability.. Go heavier for sure.
I will call what the guy below is having issues with as "Operator Error" and not an issue with the material, or design. You don't take a sports car off road and just like driving a bulky 4x4 on a race track wouldn't be that much fun either. You could in either situation, but when things get broken, or everyone is passing you.. These pants have to be put in context for what you are going to be using them for.

Durable as tissue paper

    D I bought these pants for a trip to Switzerland due to there light weight. Well after two summits these pants look rough after one glissade on wet snow there was two one inch tares and one two inch tare on the butt didn’t expect that from sliding down on snow. During one summit I had to climb over a rock and the front part of my thigh brushed up against it causing a nice size tare in the front along with other small holes.For the bottom of the pant the reinforced inner cuff of the pant was torn with a Crampon strike. These pants are lightweight and breath well and pack real small in a pack the sizing chart was accurate for fitting. I would not recommend these pants there are others on the market that would perform better for the price range that these are offered in.
