Rated 5 out of 5 by from Legitimate durable waterproof hardshell. Got my girlfriend and I lost on an old crumbling granite mountain in the Wichita Mountain National Wildlife Refuge resulting in a grueling four mile bushwhack/boulder crawl in forty-five degree pouring rain. On several occasions the boulders were too steep to walk across, so we slid down them on our asses. To my astonishment, even after pushing through the scratchy post oak and conifer thickets and sliding across super rough granite slabs, the pants (as well as our Arcteryx jackets) were completely unscathed, and kept us completely dry. Even more amazing is the fact that my girlfriend didn't dump me after we made our way back to the trail.

Rated 5 out of 5 by from Super Pants When you need one pair of goretex pants to last a lifetime and perform incredibly under any circumstances, there is only one company to utilize. Arcteryx is worth the excruciating pain on the pocketbook and moosejaw lessons the effects with great rewards points and price matching. The price matching process was easy and the representative was very helpful. Purchased these for mountaineering endeavors in Colorado as well as a lighter weight back up to my cold weather gear. Do a good deal of ice fishing and winter camp in northern Michigan. Excellent hardshell pants. Great fit and uninhibited movement without bunching.

Rated 5 out of 5 by from rocktastic I am 6.1 32 inseem 215 pounds and i have a pair of XL regular. they are a bit baggy and a tad long. I'd say overall the fit is comfortable for me. roomy enough.These are just like the bibs without the extra material. I honestly wear the bibs more. Like the bibs these have gaiters but lack the almost full length zipper. good enough to vent.They have big pockets as well where the bibs do not. Overall a great product and a nice alternative to the full bib. dry and warm as always. Enjoy!As a disclaimer, I am affiliated with Gore for product testing of Gore-tex products for the purpose of product review and recommendation. I do receive items from Gore for these purposes.

Rated 5 out of 5 by from tough as nails ,,Like all Arc Teryx products, this one is tough as nails. Reinforcement where needed but still light weight enough to take with you on hikes. The side zippers are great to vent off a little extra heat. If needed, there is room underneath for some extra layers for warmth.,,,,Overall a great pair of pants to take when hiking in the wind or when weather is threatening.,,,,As a disclaimer, I am affiliated with Gore for product testing of Gore-tex and Windstopper garments for the purpose of product review and recommendation.

Rated 5 out of 5 by from Tough enough and bone dry inside After 9 cold, wet days hiking in Tasmania, I am well impressed with these pants. The exterior is tough enough to not worry about when scrambling up scree covered mountains - reinforced knees and seat and an extra tough area around the ankle that is definitely crampon (or micro-spike) proof. The built in gaiters help keep the tops or your boots clear of muck and are probably sufficient for snow or rain. Still want real gaiters for properly muddy hiking conditions though. ,,Inside, bone, bone dry. I was never anything other than dry in the pants department when wearing these pants. The enormous side zips didn't let any moisture in and are great for venting during dry spells.,,I can not find a fault with these pants performance. If you can tolerate the price of entry, you can't do better than these.

Rated 5 out of 5 by from Great, totally waterproof pants I have these pants and the Alpha SV jacket. It is a SUPER EXPENSIVE combination, but they both do as well today as when I first bought them. The pants are comfortable, adjustable to fit as needed depending on layers, easy to get on/off over boots with full side zippers, and completely waterproof. They are lightweight but feel completely top notch on quality. The gaiters work in a pinch and help keep boots/feet dry. Highly recommended if you're looking to make the investment.

Rated 5 out of 5 by from Great Waterproof Mountaineering Pants !! I got these as a replacement for a worn out pair of MH paclite Gore Tex Pants. So far, no complaints, very sturdy construction, the reinforcements around the ankles are great when using crampons! Built in gaiters are certainly a well thought detail in these pants as well.,,,,Arcteryx has done it again! great pants, definately a must for alpine climbing, ice climbing and mountaineering. Great Pro Shell Outer layer.

Rated 5 out of 5 by from These Pant Are AWESOME!!!! I wore these pants on the snowman trek in Bhutan through all different kinds of weather. It rained on us for the first 12 days of the trek and I was always comfortable and dry. I heard some complaints from other members of my trek about being wet, but the Arcteryx, as always, came through and I was not one of the people worried about the rain or snow getting to me. ,,,,Thanks Arcteryx!!!

Chest / Bust - Measure around your chest / bust, holding the measuring tape under your armpit.

Waist - Measure around the natural waist, which is often the narrowest part of your waist.

Hip - Measure around your hips at the widest part.

Sleeve Length - With your arms in a slightly bent position, measure from the center of the back of your neck, along the length of your arm, to the wrist.

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.

Hand Width - Measure the circumference of your hand around the knuckles, excluding the thumb.

• 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.
