The queen of all softshells: fleecy soft, with wicked-good protection.

The Arc'teryx Women's Gamma MX Jacket is the softshell to end all softshells. This jacket has been awarded by Climbing Magazine and the Polartec Apex Awards due to its all-weather versatility and enlightened design. The Women’s Gamma MX Jacket uses seamless, gusseted underarms to eliminate bulk and provide a trim and flattering fit. This unique fit lets you enjoy unparalleled freedom of movement for climbing, hiking, or ski touring. The jacket’s seam design contours a woman’s shape and stretches liberally to maximize mobility. The jacket’s Polartec Powershield material feels fuzzy on the inside and helps draw perspiration away. The material’s smooth exterior resists wind and water so you can stay outside longer and much more comfortably. Sleek pockets on the chest and arm hold little necessities you like to keep on-hand.

What would the the difference in wt btwn...

What would the the difference in wt btwn this jacket and the 2009/new gamma jacket ? I tried the new one on at the store and love how it feels and fits and it's lightwt. I'm wondering if this jacket is as lightwt as well.

Responded on

The weight is listed as the same for this version and the new Arc'teryx Gamma MX. The new version has a softer feel, dries more quickly, and doesn't have the contrasting chest pockets.

2+ Season Jacket

Bought the Gamma MX for my wife about 2 years ago and she's worn it for over half of each of those years. The jacket has performed well in spring, autumn, and the milder parts of winter. It cuts the wind and is fitted enough for her to have on up to 2 merino layers underneath for when it's a bit chilly. The face of the Gamma MX also is very water repellent. She can cram plenty into the two breast pockets thereby keeping the cozy hand-warmer pockets free for their intended use. The cut of the arms makes it so if she were climbing around/raising her arms a lot the jacket doesn't shift. The jacket has held up quite well over these 2 years as well. All in all a great 2+ season jacket!

Can I use my 25% coupon on top of the sale...

Can I use my 25% coupon on top of the sale price?

Responded on

most likley not, usually the coupon are the better of the two deals, but theres no harm in goin into the checkout area and entering the code just in case :-)

Responded on

Typically the coupons work like this:
If item is on sale then you can't use the discount unless the item on sale's discount is less than the % of your coupon. i.e. Shirt 20% off on sale - your coupon would boost that sale to 25% of the original tag price, not the sale price. However, as Cyrus pointed out its not going to hurt you to try. Having said that I must warn you I have recently run across a bug in the CODE COUPON system and have lost out pretty big...can't go into details bout my situation until it has been resolved, sorry. So, I would hold onto that COUPON and save it for something you can definitely get your 25% off on. IMHO, I just wouldn't take the chance given my recent (last 24 hour) experience. Only asnwers I can get thus far from gear heads is that there's a bug in the system and so now Ive been passed off to marketing and the ultimate powers that b @ BC. Try your luck, though it may be a gamble or just wait and use it on something the discount would do you some good on. Good question tho and hope I was able to help shed some insight for you. If you're new to Backcountry I encourage you to utilize the live chat with a representative. The 'gearheads' are very helpful, friendly, and provide great customer satisfaction. Ive been dealing with BC a while now and have only just recently came across an issue they couldn't give me an answer for, but my case is a strange one. warned that they have a lot of new reps these days that are still learning the ropes so you may want to talk to a couple of them for a lil checks and balance for your questions. But seriously, they truly are a delight to chat with about gear and for the most part are pretty informative and useful! They'er actually priceless to me!

Best Answer Responded on

That's going to be a no. It will only accept the better of the two discounts. That would be sweet though, 25% off of an already 40% discounted item! I think BC would be loosing some money at that point.

Gamma MX- DO IT!

This jacket is primo- fit is great, you can easily layer for colder days and it is completely waterproof. I wore it in a storm on the mountain and never got wet. It's also super stretchy and flexible for climbing or vigorous activity. The quality cannot be beat. Plus, it looks good!

I love it, but don't wear it much...

This is a great softshell, but I've worn it like twice. In the NW, a rain jacket or down jacket always seems to be a better choice. Maybe by spring time this will come out of the closet more, but the conditions are not the best here for this type of jacket. Would recommend for a warmer climate since the jacket is very thin and not really warm.

do you still have the jacket? Want to sell it?

If you like a softshell freedom of movement jacket with lots of pockets, this is the jacket. Its got 2 chest, 2 hand and 1 sleeve pockets. It is great for layering. I've used it for rock climbing, skiing, snowshoeing, and just around town. This is my favorite jacket. I have 2, 1 black and 1 Aloe color.

My Green Coat!

love this coat!! the small was a little too small across the chest so i had to go with a med which was longer than i wanted but beyond that it's been great. hyper wind resistant and all around great for skiing.

How do you determine the correct size? Do...

How do you determine the correct size? Do you have some information to help me determine this?

Responded on Most of the jackets for alpine climbing, mountaineering and ice climbing run a little more snug, while the skiing and snowboard jackets are a little roomier. All of the jackets have an athletic fit, broad shoulders, narrower waist.

Superb versatile jacket

This jacket proved to be worth the dinero. The woman was well protected from the elements at all altitudes on our journey to Switzerland. Wind, wet, snow, it made no difference with this garment. My men's version functioned with the same results, 'Outstanding'.

Great Jacket....

This jacket is a great fit and style, great technical details, and it's both warm and waterproof....very important if you live in the northwest. A bit pricey, but worth it.

perfect fit!

I can't wait to try this out in the cold weather. This jacket is a perfect fit (I actually went a size smaller than normal). It has great flexibility for any activity and the seamless design adds extra comfort.

Great jacket

This jacket looks and feels great in a multitude of climates. It packs exceptionally well and does not wrinkle. Best of all it really moves with you and breathes.

It's not cold enough to try it out yet, but it looks and fits amazingly.

The greatest

No doubt,THIS IS the jacket you want to have. I walked down to my martial art training center this evening with just a teeshirt under the jacket...ABSOLUTLY NOT COLD, no kidding. Oh, by the way the weather tonight in NYC (02/28/05)was very windy and snowing.
It blocks the wind totaly and not a single drop of water found his way thru.

gamma mx jacket!

Excellent fitting jacket with one or two layers underneath. Flexible enough for long stretches on the bike. Sheds water like rain-x yet still breathable for the body. Compliments abound everytime I wear this jacket! Must be the sexy Sangria red!
