Using GORE-TEX® Pro 3L fabric, this jacket provides waterproof protection that is lightweight and packable.

An adjustable hood that fits over your helmet, a single chest pocket and adjustable cuffs keep you functional through the rain or snow. Even the hem stays put underneath your harness.

Product Reviews
Rated 5 out of 5 by from Very light, but windproof shell This shell is incredible light and thin, but is impressively windproof. I've tested it as a windbreaker on a multiday autumn sailing voyage around Marthas Vineyard and Nantucket and it cut the wind extremely well. No insulation underneath so requires a midlayer fleece or down jacket underneath, but looking forward to layering it up and hitting the slopes this winter. Fit is classic Arcteryx - snug but not too tight, in a way that's forgiving for a retired endurance athlete but may be too tight if you're not close to in-shape. I'm 5'11 170 and straddle M/L in most brands - this M fits great as long as I stay trim! [This review was collected as part of a promotion.]

Rated 4 out of 5 by from Great jacket I'm super happy with the jacket so far. Im 6'1" and 185lbs in a lean body build. I originally ordered a large (my normal jacket size), but it was way too big. I exchanged for a medium and I'm much happier with it. There's still enough room for me to layer a 750 fill down jacket underneath, but I don't look like I'm swimming. The hood fits great with a helmet, or you can cinch it in the back to keep it from draping over your eyes when you're not wearing a helmet. As for the jacket itself, all the seams are good and the gortex it doing its job keeping me dry. I wish it had pit zips but it's not a huge loss. It's more important to me to know I can keep warm and dry. [This review was collected as part of a promotion.]

Rated 5 out of 5 by from Probably still overkill for me I picked up an Alpha SV as a winter, do-everything, bombproof shell. I hadn't owned a winter worthy shell for quite some time. This was purchased as a lighter, warm-weather shell. I've been wearing it more because the temperatures have been a little warmer and I've been pleased so far. The lack of pit-zips hasn't bothered me yet. I wore it shoveling and still had to strip down layers but it didn't get damp inside. It's worked really well in the rain so far as well. I got a size Large (6'4" and 220lbs, broad shoulders) and you have room for some thin layers under it. The length is fine but some shirts may stick out at the front; doesn't really bother me after the initial wear. [This review was collected as part of a promotion.]

Rated 5 out of 5 by from Arcteryx is simply the best Used on a climb up Kilimanjaro. Rained for several days non stop. Not even a drop of condensation on the inside of this jacket. It is truly waterPROOF. It kept me completely dry while others I was with were soaked in other Gore-Tex jackets. This is just the best choice. [This review was collected as part of a promotion.]

Rated 5 out of 5 by from Great Shell This shell packs down smaller than a soda can in a small stuff sack that's provided. It can also be packed into its own hood if you lose the sack or want to save a fraction of an oz. It's very light and cuts the wind and rain. I just took in on a few day backpacking trip and it didn't take up much room or weigh hardly anything at all. I'm 5'10 165lbs and the medium fits perfect. I can get a base layer and even a nano puff under it if I need to. [This review was collected as part of a promotion.]

Rated 5 out of 5 by from Amazing Features and Design I have not had a chance to use this jacket on a climb but I am already very impressed. The compressibility of the jacket is amazing- the stuff sack is the size of the palm of my hand. The fit of the jacket is perfect for technical climbing. The sleeves are a little longer, the length is perfect for use with a harness, and the hood design integrates well with a helmet. I wish I could take it out in full conditions right now!

Rated 5 out of 5 by from Great Lightweight Shell Used this jacket for about half a year now from Midwest Blizzards to Crazy windy tops of Colorado 14ers. I love the pack size of this jacket (about the size of a 16oz can). Its lightweight and hardly notice its with you. I have not been in a total downpour for long periods of time to really test its waterproofing. Hood is highly adjustable and confortable. Works well with my climbing helmet [This review was collected as part of a promotion.]

Rated 4 out of 5 by from Works great, sizing is difficult 6'1" 165lbs - Initially bought a L but felt baggy. Swapped for M and feels too short in the front. I use this for snowshoeing and snowboarding and it works great. Since I use a bib snowboarding the short front isnt an issue. I layer this with the fairly small puffer for snowshoeing and its perfect. If I had to use a larger puffer or didnt have a bib I would have stuck with the L.

Warranty Info

Arc'teryx Warranty and Repair

Arc'teryx guarantees the quality and performance of all of their products. Items with defects in materials or workmanship will be replaced or repaired at the discretion of Arc'teryx for the practical lifetime of the product. Items that are damaged through wear and tear, misuse, or neglect may be repaired at a small charge.

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.

How are shipping costs handled?
