Product Description Item No.   10207146

The Arc'Teryx Men's Gamma Rock Pant is a softshell pant for climbing. Rock or alpine climbing, pick your poison, and get outdoors. The Fortius 1.0™ fabric is a blend of nylon and elastane for stretch, breathability and weather resistance on the climb. The high-abrasion areas are covered with the incredibly durable Burly™ double weave fabric, a nylon, polyester and elastane blend that lets you scramble along on your knees or butt without worry. Your hard work will inevitably bring about plenty of moisture from sweat, but these two fabrics will kindly allow the heat to pass through without protest. The exterior is finished with a durable water repellent coating, which prevents light rain from soaking in during an unexpected shower. Enough protection to give you time to dig out your rain pants, wait out the shower, or get under cover. Zip small items inside the hand pockets, so in case of a fall, you'll still have your lip balm. An integrated webbing belt holds these comfortable pants up on your hips, without getting all bulky under the harness.

Rated 5 out of 5 by from Excellent fabric weight, good fit and looks I was looking for a good all around outdoor pant for hiking, camping, climbing, etc. I tried on the Gamma LT, Gamma AR, and these. The LT fit great in Medium but I wanted something slightly more substantial material wise. I tried on Medium and Large in the AR and neither of them fit me because the medium was just too tight and large was way too big in the waist - but the Burly material was more along the lines of what I was looking for. So then I tried these Rock Pants in size Large and they fit great, the waist is larger than needed but should be Okay due to the buckle system - which I really like over the other Gamma models. I'm 6'0 and 180lbs. The reinforced Burly areas are perfect and the Fortius keeps them from getting too hot. I like that there are not any cargo pockets (like other Gamma models). Overall I just think the style, material and fit works great for my all around use. I can easily fit a base layer underneath for colder camping nights and they seem like they will be tough enough to take fairly heavy use.

Rated 5 out of 5 by from Outstanding bit of kit Fantastic trouser thats really comfortable, sheds water & dry's extremely quickly. The clip on the hem to fix to your laces is a great addition for climbing and general mountain use. I've found them ideal for multi dayers as they shed mud really well which means you don't have muddy kit in the tent or have to put dirty kit back on. I will be buying a second pair.

Rated 4 out of 5 by from Good pants, but not as all hardy A long time ago in a galaxy far far right here, Arcteryx made an alpine climbing pant called the Agent Comp, made from ballistic nylon with double layering over the whole top of the thigh to well below the knee. They were neigh invincible, and I have been looking for their successor since their demise. The Gamma Rock is not their replacement. These pants are thin, light, breathable, and stretchy. The light and stretchy is good, but the thin and wind-permeability are not. We'll see how they hold up after a few weeks on the wall wedging my knees in places my knees ought not be.

Rated 5 out of 5 by from Great pants! These pants are the best I have ever had. Fantastic fit and they look really good too. Used the Arc'teryx fit calculator and it suggested a size Medium, which I ordered and the fit was perfect! I am 188 cm/6'1" and 75 kg/165 lbs.

Rated 5 out of 5 by from Best pants I've ever had I have been using these pants for about a month, and have worn them almost every day. They have no rips, despite being constantly dragged over granite, and quite a few miles of thick bushwacking. Seriously contemplating getting another pair, as these are the only pants I wear!

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.
