DWR tech

Durable Water Repellant
DWR (Durable Water Repellent) is a coating that is applied to fabrics which makes them water-resistant, or hydrophobic. A DWR finish doesn't interfere with breathability, which makes it perfect for adverse conditions in the backcountry.

Rated 5 out of 5 by from The Perfect Winter Softshell This is the perfect winter softshell. The balance of wind protection, breathability, and water/snow resistacne is outstanding. Warn while hiking and snowshoeing in the Bavarian Alps, and while x- country skiing in Michigan makes evident the moisture management abilities. Moderate Rain and Snow did not have me reaching for my hardshell. Fit is outstanding, I'm 5'11" @ 170lbs with a 32" waist and 34" inseam and the Medium Regular fits perfect. Worn alone or with a base layer, the movement is totally unrestricted. Features layout and pockets are great, one zipper, and one velcro makes glove and hat change quick. Herron Color is fun, and yet timeless.

Rated 5 out of 5 by from Love these Pants Just want more colors (Khaki) These are amazing pants work very well for skiing with another layer and hiking just as is. They are three season pants except summer when they are too warm. My current pair are several years old made with Polartec and they are still perfect shape. No sure if they are using Polartec yet. They are water resistant and breathable. I am 6 ft, 230 and I wear a large and they fit perfect. I have 36 waist and 30 inseam and they fit perfectly. The Cargo pockets are amazing and zipper front top pockets are perfect. Wish they had two rear zipper low profile pockets for functionality. Need to add the khaki color and stop making your products in China because I fear the quality will suffer.

Rated 5 out of 5 by from Versatile & Functional Pant Comfortable enough to wear on a walk without overheating. Wicks away light and heavy rain, dries quickly after being submerged in water. Temperature regulation is good enough to support a wide temperature range while still providing protection from moderate wind. Durability seems to be solid, with no detectable burrs or marks from bushwhacking through thorn bushes and deadfall. I'm very impressed with the low end versatility of the pant - at the low end of technical activities - it's more adept to above freezing hiking and lounging around than I would expect for a pant designed for more hostile environments. Going forward I plan to use these with a thin to moderate base layer & packed shell for complete lower body protection. The moisture regulation of the material is reliable enough that I don't anticipate needing another primary layer on mild days or cold days when very active. Sustained rain or snow probably should be met with a w/b shell, but in the majority of situations ranging from fall through spring these should do quite well.

Rated 5 out of 5 by from Great all around 3 season pant I have these pants now for almost four months and used them for skiing tours, cross country skiing, hiking and (ice)climbing. When on the move their warm enough by themselves 'till minus 10 degress celsius. If the temperature falls below that, it's to time put on the long underwear. At the same time these pants do not feel to hot, when hiking at 15 degress plus celsius. It hasn't been warmer than that. So I don't know when they'll actually will be to warm. So the temperature range is quite impressive. They are very wind resitant, but not wind closed. That helps to prevent you from overheating and sweating. The material seems really tough. They don't have a scar yet, even though I brush rock and hard ice with them quite a bit. On top of that they're impressivly water resistant. I stayed completly dry in them on a two hour long descent in a constant rain and hail storm. At the end, the outer material show a couple of wet spots, but none of it soaked through. I highly recommend them for fall, winter and cold spring days.

Rated 3 out of 5 by from nice pants but not my favorite I was hoping these would be my favorite pants for iceclimbing, fall climbing and early spring. first the construction is great, but I asumed they would fit very similar to the Gamma LT? The Gamma lt fits a little smaller and has the articulated knees the MX is straight. The belt is elastic at the back and if the pants are big in the waist the belt cinched up helps but the elastic sucks as you cant keep pants tight at waist. pockets on thigh especialy the right velcro closed poicket is used a lot I love the pockets. I dont know why Arcteryx would not have added the gaitor hook at the front of pants ?????? would have been nice. the lower legs are very bagy. I wore these on an alpine climb / scramble weather light rain and about 7c pants beaded water up great I was a little warm but not bad. if these pants had articulated knee and fit a little smaller I would love them. I suppose when layered for -30c they will be fine as i have lots of room for layer. For comparison I did try the new psiphon AR pant they are a very nice pant but size large is huge in the waist and tight in the thigh / but area I am an athaletic build 185lb 5'11 but had to send them back as no room for layers and the waist puckerd up as it was to big

Rated 5 out of 5 by from Comfortable and rugged To protect my legs, I wear Arcteryx Gamma softshell pants for hiking. They've a more comfortable cut than corresponding Kuhl pants. The Gamma AR is fine for warm days (60 F to 90 F), and the Gamma MX is perfect for cooler days. I've worn them as XC ski pants when it was -10 F, under a GoreTex ski bib, and I was warm and comfortable. Gamma MX pants are like a modern upgrade to wool pants, lighter yet performing better. They can get damp, not soaked.

Rated 3 out of 5 by from An MX review of an MX item... I wore these once (yes once) and the stitiching above the knee 'came out' (un-picked from the seam). From the other reviews, I think I must have gotten a 'Friday Afternoon' pair, it's a bit dissapointing as I took them on one of the easiest hikes in the UK (Malverns) and didn't abraid them at all. I have since fixed them with a bit of superglue and a very hot needle, but this is less than I expect from an Arc'teryx product. Also, if you have big thighs, then I reccomend going up a waist-size, I find these tight when you're wearing a base-layer (and no, I'm not a fatty). Since the above, I've beaten them up a lot and they held out superbly, better than any other single piece of gear I own. so it's hard to complain (well, much more than I have already). I think that Arc'teryx set such a high bar for themselves it's difficult not to find fault.

Rated 4 out of 5 by from 4 outings and wish I'd found the AR or Guide. regular length is way too long! second day out I poked a hole in them. I've got a bunch of fabric folds just waiting to grab something. the waist and belt are nice, the pockets are well sized, the DWR held up well to above freezing temperatures climbing up a route plastered with wet snow.

Inseam / Pant Length - From a standing position, measure from your crotch to your ankle.

Head Circumference - Measure the full circumference around the widest part of your head.

Hand Length - Measure from the tip of your middle finger to the base of the palm.

• Please note that all the info provided above refers to body measurements, and NOT the dimensions of the garment.


Next to Skin Fit - These snugly-fitting garments are made with stretch fabrics to fit next to the skin to enhance moisture management and thermal efficiency. Garments in this fit category when constructed using Arc'teryx's heavier-weight AR and SV fabrics also perform very well as mid layer pieces, and users should consider selecting a larger size to accommodate a base layer underneath if the intention is to use this layering system as a mid layer option.

Trim Fit - Trim-fitted garments share the motion-friendly traits with Arc'teryx "Athletic" fit garments, but are patterned with lower volume for reduced bulk. These close-fitting pieces layer well under other garments.

Athletic Fit - This is the "Arc'teryx Standard" fit. These complete patterns utilize anatomical shaping and gussets to enhance motion by minimizing excess bulk. Easy layering under or over each item extends seasonal versatility and comfort.

Relaxed Fit - Relaxed fit garments rely on higher volume patterns and a reduced amount of articulation to offer roomy mobility.

Expedition Fit - Cut roomier than the Arc'teryx Athletic fit and suitable for winter/extreme conditions, Expedition (XPD) fit garments are cut larger to accommodate multiple layers without binding or restricting movement.

• You can find the fit type and additional fit info for Arc'teryx styles in the product description FEATURES and SPECIFICATIONS.
