There's nothing worse than going for that fancy move with your foot and putting your crampon right through your brand-new pants. Not to worry, Arc'teryx added reinforced instep patches on the Men's Psiphon AR Pant to prevent crampon stabbing and the inevitable nicks and slices from ski-edges. The alpine-specific trim fit reduces excess bulk without hindering leg motion, and three total zippered pockets make sure that you have access to your valuables during the course of your day. The burly, 4-way stretch fabric makes sure that if you can't make the reach on your latest climbing venture, you'll at least know it's because you skipped yoga, not because your pants could flex far enough.

Great fit but loud.

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: True to size
  • Size Bought: XL

I bought these for cold weather activities and quick day hunts in Montana. I was disappointed they are so loud for a soft shell. Not sure if I will keep them but dang they feel nice and fit good. Really hard to find good active softshell pants for a 40 waist but these feel like a perfect fit in XL. Not sure if the fabric will soften up over time. I am right between XL and XXL and most XL in Arcteryx is too small and 2X is too big but these were perfect. . Even if I wasn't using them for hunting I don't like loud pants. Very strange no one else has mentioned this.

Great Pants

Have you ever been asked what book you'd take if you were to be stranded forever? The Psiphon would be the pants I'd take to any mountain if I had to make that choice.

They are elegant, well designed, fit well, warm - I can't say enough good things about them. In short - a mountaineer's dream. Forget all the rest.

Awesome Pair of Pants

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

I wore these to a recent backpack trip through Yosemite in the winter time and this pair of pants did a great job keeping me warm and dry. They are also very breathable that my legs weren't wet with sweat when I thought they would be drenched.
I was debating whether I should wear a pair of leggings underneath for the extra warmth, but I decided not to. If worse comes to worst I could always put on a pair of leggings and then toss the pants back on and warm up that way. Amazingly, this pair of pants kept me warm and dry throughout the day and even at night when the temperatures hit 10 degrees. Definitely can't wait to use this as a pair of snowboard/ski pants. Adios bulky snow pants!

You should want to get into my pants.

You should. They fit great.

Finding a great soft shell pant can be a very daunting task. I am just a few inches taller than what would be considered a midget. There are so many companies with 32" and 34" inseams on their regular mediums. No way in hell that is going to work for the vertically challenged people like myself. These pants are 30.5" in their regular length. Works for me.

I have gone through researching so many pants from so many different companies only to find they are too long. And until Willy Wonka starts making Oompa Lumpa climbing pants for the masses, me and my brethren are up Shit Creek without a paddle. Or at least with no pants on.

So, these pants fit great. The material is very stretchy and very comfortable. I was initially worried about them not having a reinforced instep from the pictures I was seeing. They do. It has been put on the inside of the pant leg. Awesome.

The waist band snap and stretchy hook connector is very nice as well. With gloves on, forget it.

The zip at the bottom to expand the cuff is very nice and just beckons to shove a ski boot in there. Which is even more adjustable with a snap to customize even further.

I also like the tabs on the cuffs so you can add a cord to keep the pants down if you are venturing into the snow.

Comfortable pockets and a fairly large thigh pocket on the right leg .

I would say for an athletic cut soft shell pant that can do duty as a hiking, climbing and ski pant. This thing has got you covered as a great do everything pant.

Didn't change for 10 days

  • Familiarity: I've put it through the wringer
  • Fit: True to size
  • Size Bought: small

Wore these suckers for 10 days straight on Denali.

Pros:
- Extremely comfortable
- Very water resistant
- Very wind resistant
- Extremely breathable
- HUGE pockets
- Has small loops for attaching a bungee to use pant legs as gaitors.

Cons:
- "Belt" is hard to operate with lots of layers and gloves on.

Hey Joshua,

I'm about the same weight and height as you.. Just wanted to see how you liked the small fit? Will be using for ice and some ski mountaineering. Thanks!

Hi Joe,

Am off to Denali in early May and need a solid pair of soft shells. Would you have considered the Gamma MX pants for extra warmth or were the Psiphon AR's just perfect. Did they fit over the climbing bots ok (I've got the Oly Mons)? What base layers did you use underneath?

Awesome sauce!

After trying pants on all winter and spring, finally found these. They fit great, breathe pretty darn well while still blocking the wind, and shrug snow and some rain with ease. They're surprisingly durable - I post holed alongside a rock, and came away with only scratches, and couldn't find any wear on the pants. I've also kicked the instep patches pretty good a couple times with crampons, and have been grateful for their protection (whoever thought of putting the patches inside the pant - genius). Zipped up, the ankles fit perfectly over Nepal Evos (no need for gaiters, even post holing), and unzipped fits nicely over AT boots, or allows for the pants to be rolled up for those sweaty approach hikes. Pocket zippers move easily, and pockets are comfortable even when crammed full of cameras/food/etc. Get the idea? I love these pants!

Finally found the best athletic-fit pant

  • Size Bought: Medium

Have been searching, buying, trying on, etc. for the past 3 years. It is really difficult to find a pair of ski pants which are not baggy - snowboarder style. These are perfect - trim fit , inseam at ~31" is great length for me over the ski boots or hiking boots. Stretch softshell fabric feels good against your skin and is reasonably windproof and water resistant. and allows for freedom of movement. Waist closure is great - nothing to break or get loose. Medium size fits my 33" waist perfectly, even with merino bottoms and top bodyfit merino T-shirt tucked in. Great pants for a great price.
