The Arc'Teryx Men's Beta AR Pant is a waterproof pant for all around action in the mountains. Rain, mud, snow and more, the N80p-X and N40r-X GORE-TEX® Pro 3L fabrics play stellar defense against all the wet elements, and even the invisible wind that is so hard to stay away from. Staying dry keeps you comfortable and keeps you moving towards your goal, whether you're headed to the top of the mountain, back to the trailhead, or somewhere in between. The Arc'Teryx Nu water repellent treatment repels water from the fabric surface and taped seams increases waterproof protection. The pant has been specifically patterned for mobility and comfort in an athletic fit that not only looks good, but won't get caught on gear or the brush you just walked past. A hip pocket for stashing goodies, 3/4 length leg zips for easy on off, and Keprotec™ instep patches for protecting the pant against sharp edges, crampons and more.

Rated 5 out of 5 by from perfect Arcteryx I have worn them skiing, hiking and when joy outside.,The side zippers are awesome in that you can get your boots on and then throw the pants on and just zip them up. Ithey are the best cold weather pants I have ever owned. Sturdy, light, and comfortable. They were expensive but you get what you pay for.have met the harshest of winter and wet conditions. They have endured countless crampon strikes on the inner ankle areas and the reinforced material stayed strong.perfect Arcteryx

Rated 5 out of 5 by from great all round pants I took these on my summer and fall hikes CO, ski tours, and even took them along on some mountain biking trips. They are very light weight and fit over shorts or even tights. Great product.

Rated 5 out of 5 by from A true all rounder When I bought these I wanted one hardshell pant to rule them all, that is I wanted pants that worked for everything so I only needed to have one. And these are the ones. I've used them for everything from rain protection in the summer while kayak camping to skiing/snowboarding in the winter. But as the true all-rounder they are they don't excel at anything. And now that my beloved pants are starting to fall apart on me after intensive use I will get two different pants, one pair for winter use and one for summer. Simply since in the winter while skiing/snowboarding I miss the warmth and protection at the lower back you get from a bib, and in the summer I would like to have something a little softer to wear directly to skin and to not have to deal with the snow gaiter while getting them on/off with boots/shoes on. But if you only want one pair of hardshell pants to use for everything these AR the ones.

Rated 5 out of 5 by from When SUl & ULdilettansim have had their shot. I gear up to have the lightest weight, durable-enuff, equipment/gear per outing. That means that my equipment list per outing is going to vary a bit depending on the environment I'm heading into, the duration of the outing, and the tasks I envision are ahead of me. For most of my outings, the Beta AR is burdensome overkill, weighing in at over 500+ grams (I own the size 'Long Tall'). My latest 'stay dry' top 'n bottom shells weigh approx. 200g a piece. Perfect for 70% of my outings where they tag along for just-in-case scenarios. Such was their task this summer when I spent 2 weeks hiking about for my first time in northern Slovenia. Their miniscule weight was really appreciated and they tided me over superbly during one single precipitous event - a 4-hour torrential downpour near Blegos mountain. After Slovenia I did 4 weeks of solo sail&hike off the coast of mainland Dalmatia (southern Croatia). My rain gear saw zero action and again I was happy that the shells weighed a pittance and packed down to next to nothing. However, earlier this year I flew over to Bosnia and did a spur of the moment 6-day solo winter-hike in the hills and valleys surrounding Sarajevo. The weather was awful every day and night and I ended up taking refuge in my Beta AR's most everyday. If I never had them on when I set up camp late in the evening then the first thing I did once I found a spot to pitch my Hilleberg Unna was to pull on my Beta AR's. I put those pants through h*ll during that week in Bosnia (bushwacking, glissading, falling, kneeling on mean ground) and the pants came out in onc unscarred piece whereas any of my just-in-case, gram-weeny shells would have been obliterated. Not only that, but the pants (along with my Beta LT jacket) played a significant role in contributimg to my thermal comfort while both moving and stationary (their materials' relative sturdiness compared to a purely wind resitant weave (ie Squamish) better protected the loft of underlying 'puffies' when the wind hammered me). This spring was miserable in the parts of Scandinavia I usually hang out in; being mostly over cast, day temps in the mid-teens, and lots of nagging precipitation day and night. During this crummy spring I was asked out of the blue to be a guest SERE instructor for somebody's armed forces. I brought along my Beta AR's and ended up donning them throughout near each of the course's 6 days--wearing them un-caringly, and at times subjecting them to rather vicious abuse. Normally, I would be squeamish about such abject punishment of expensive equipment. In this milieu and context however, there was little acceptable room to behave as a pamperer of shiny gear (an otherwise quite acceptable and responsible behaviour when going SUL or UL). The Beta AR's held up faultlessly. Only time I had to baby them was when we instructors built a fire and sprawled out about it for some late evening BS sessions- I couldn't lie to close to the warming fire without risk of melting my Beta AR's. (The regulars all wore mil-issued clothes made of a tight cotton weave.) So - the Beta AR's are good for significant abuse should matters come to that. They keep out the wet and wear most comfortably per design/cut, especially considering that they're made out of a robust and relatively unyieldy material (ie 3-L high denier hard-shell). So-called breathability was never an issue when worn in sub mid-teen (Celcius) climes. In Bosnia I wore thin merino lomg johns and Gamma Rocks under my Beta AR's. During SERE I wore just a pair of synthetic long johns under the Beta ARs. I don't know how the Beta ARs would fare in warmer temperatures as I haven't encountered a fair weathered scenario where a pair of lighter shells wouldn't suffice. I'd only pack these pants if I envisoned wearing them more than carrying them. The belt functions 'unimpingingly' in combo with a backpack's waist belt, imo. The built in gaiter functionality of the pant is brilliant and robust--a feature that proved fantastic when ipostholing about through snow storms in Bosnia.

Rated 1 out of 5 by from Very very disappointed I bought these pants last summer because I read lots of positive reviews for this product. I really haven't used them very much, and only 3-4 times i heavy rain. I used them today walking to work and the water went straight through them. It looked like I had wet myself. This was really disappointing. After all, this is a very expensive pair of pants, and I really expected more from Arcteryx. I have other Arcteryx products, and I am very happy with those, but these pants were way below my expectations. Sad, but true.

What is the inseam for the large short and ex-large short.

Asked by: birds
Hey there, Thanks for the question. All of the sizes in the Short option of this pant have a 30" inseam, while the Regular has a 32" inseam. I hope this helps!

How do I send back an item for Warranty, or get an item repaired by Arc'teryx?
For Customers in North America and Europe, Arc'teryx recommends that the product be returned to the store or site where it was originally purchased.

If this is not possible, fill out their online warranty form which can be found HERE. They will email you with full instructions on how to send your product to their Warranty and Repair Center. Do not send your item to them without first obtaining an RA number from Arc'teryx.

Arc'teryx is not responsible for items that are lost or damaged during shipping and cannot replace parcels that are lost during return shipment if proof of tracking is not available. Please use a guaranteed delivery service that provides tracking information, insurance, and proof of delivery when sending an item back to Arc'teryx.

For customs purposes, Arc'teryx requires you to provide them with a PHYSICAL address, however, your warranty/repair item can still be shipped to a PO Box.

How do I contact them with questions?
Complete their Warranty or Repair Request Form. If you have any questions or concerns, you can reach their Customer Service department at 1-866-458-2473.

What is and isn't covered under the Warranty Policy?
Defects in materials or workmanship are covered for the practical lifetime of the product. Material refers to zippers, buckles and fabrics. Workmanship refers to seams, seam tape and construction. Damage due to wear and tears such as rips, tears, abrasion or UV degradation, misuse or neglect is not covered under Arc'teryx's warranty policy but may be repairable for a fee.

What is covered under the Warranty Policy on Arc'teryx footwear?
Defects in material and workmanship will be covered by Arc'teryx for the practical lifetime of the product. The practical lifetime for footwear can vary drastically depending on the frequency and type of usage. Things such as the wearing of the outsole, frayed laces, nicks and tears can indicate that a shoe has surpassed its practical lifetime. These are examples of wear and tear or damage which are not covered by Arc'teryx. If you believe there is a defect in material or workmanship present on your product, please see follow the instructions on how to send it to Arc'teryx for assessment.

What does 'practical Lifetime of the product' mean?
Although Arc'teryx builds their products to last over extended periods of time, nothing lasts indefinitely. Materials will deteriorate and fade over time and moving parts will wear out. Arc'teryx will cover your product under their warranty policy until such a time that they have deemed the product to be worn out beyond reasonable repair. If the product is showing the signs of its age-for instance, the material has become thin or faded, there are rips and tears, the zippers no longer catch, the cuffs are fraying, or the soles are worn-they will take this into consideration when assessing your product for a warranty request. All gear will suffer from differing degrees of wear-and-tear, depending upon the user. Equipment used by an outdoor guide for 150 days a year will by comparison, degrade faster than gear used by a weekend skier. By taking care of your equipment you will ensure a longer lifetime for your gear. Arc'teryx recommends that you visit their Product Care page for more information on how to wash and care for your equipment.

Will Arc'teryx repair or replace my product?
If your Arc'teryx product fails due to a manufacturing defect, where possible, Arc'teryx will repair the item at no charge to you. They have repair centers in both Europe and North America that employ the same custom machinery and techniques that they use to create the original products. If the product is not repairable, or the cost of the repairs exceeds the value of the product, Arc'teryx may, at their discretion, choose to replace the product instead.

What happens if I rip or tear my jacket or pants?
Skis, snowboards, crampons, axes and other sharp equipment will damage clothing and gloves if they come into direct contact with them. Rips, tears, burns and punctures can occur during normal use and while carrying your equipment, and are not covered under the terms of the warranty. To assist you in keeping your product in optimal working condition, Arc'teryx offers a variety of repairs for a reasonable charge. Contact them and they will be happy to discuss your options.

What if I want to have my garment altered or tailored?
Arc'teryx does not offer custom alterations or modifications to their packs or garments at this time. For products made from GORE-TEX® fabrics they suggest using a GORE-TEX® authorized repair facility for alterations. There is a list of GORE-TEX® authorized repair shops in your area on the GORE-TEX® website.

Do alterations void my warranty?
Arc'teryx understands that individuals may, on occasion, wish to tailor their Arc'teryx products to suit their needs. If something should fail which is unrelated to any alterations, Arc'teryx will stand behind their products, provided that the Arc'teryx product is being used as intended. For a list of alteration facilities in your area, please visit the GORE-TEX® website.

How long will it take if I send my product in for warranty assessment and/or repair?
The typical turn-around time is 15 to 20 business days from the time they receive your product to the time they ship it back to you. Keep in mind that winter is the busiest season for warranty and repair service. Arc'teryx will provide you with updates and more accurate estimates throughout the process.

How do I prepare my item for return to Arc'teryx?
In order to comply with health and safety regulations, as well as for the protection of their staff, Arc'teryx kindly asks that all products be cleaned before being sent to them. Products that arrive unwashed may be subject to a cleaning fee before assessments can be made. To find out how to properly clean your garment, please visit the Arc'teryx Product Care page.
