Will this jacket work for a) bike commuting and b) cross country skiing.

I have a Theta AR I bought two years ago. Great jacket that has served me very well. I really like the cut. I would like to expand my jacket options for activities where I think the Theta is less ideal.

Let me explain. I live on top of hill. I bike downtown to work. I need a jacket that can break the wind. Intended temperature range is 50 to 20. If I add in the windchill the lower temperature is about 5F. For this the Theta is is outstanding. But going back home the Theta does not breath well enough. Going home the weather is usually warmer, and I sweat way more going uphill. Would the Gamma MX Hood be a good option here?

I do some Cross country skiing, and the Theta is great for the back-country and in the mountains, but for warmer days in the tracks just outside of town its overkill. Would this jacket be a good option?

Also, how does the fit/cut compared to the Theta AR?

Thanks!

These jackets breathe exceptionally well. They allow some air through (so they are not completely windproof) It is a great jacket for XC skiing. it provides a bit of warmth (apparently equivalent to a 200wt fleece). Riding home on your bike you are probably going to sweat in this shell as well. While it breathes well it has that insulating property that will cause heat build up (even with the pockets open for venting). Try the gamma LT as a option for biking home or the celeris- each model breathes much better but is not as windproof.

BTW: Gamma MX fit much slimmer compared to the theta AR.

I am 6'2" and 238 lbs. I am considering the new Gamma MX hoody. I like a little room so should I go XL or XXL? (arm length 34-35 and neck 17.5-18")
Thanks.

Responded on

Use your chest and waist measurements too, but this jacket runs to the fitted side. Really depends on how your body mass is distributed. You might get a little more in the sleeve than you need, but my thought is that you'll get more of the fit that you want with the XXL.

any other size at lichen colour (Large)?

Hey there, you might want to keep an eye on the new version of the Gamma MX (tem: ARC1182), as they will be phasing this one out and stocking the new version....

Weird fit, over priced

I ended up returning this jacket. The reason is because the sleeves are too baggy. It's huge in the shoulders and then tapers down to nothing around the wrists. I'm a climber so I like my gear to fit close to my body. If you're a body builder with huge shoulders and neck muscles but have really skinny wrists this jacket will fit you perfectly. If you have big pectorals though forget it. The chest of this jacket is pretty slim fitting.

I still gave this jacket 3 stars though because besides the fit it is very nice. The lining is super soft and comfy BUT so over priced. While I agree, Arc'Teryx does make very good clothing, after returning it I found a mountain hardware soft shell of the same quality on sale for only $100 dollars. Unless you're trying to make a social statement by wearing this jacket, save your money. Get a mountain hardware soft shell and a patagonia R3 Fleece, it's more versatile, better fit, warmer, fuzzier fleece and half the price for both items!

If you look at the picture, you can actually see where stylist folded all the extra material in the armpits under neath so that it looks like it should in the arms. This jacket does not look like it does in the picture when you put it on. FYI.

round september there will be new colors coming along with changing the fabric that the gamma MX is made from (will now be fortius 2.0) and a slight price reduction -349
I am not sure how well the new fortius fabric will perform though.

Hey Guys,

I'm not sure quite what size to get. I am 6'1" and I weight 190 pounds but very fit and trim. I can't decide between the medium and large. I don't like my jackets to fit very baggy but rather tailored without being tight. I will be layering it but not with anything bulky (a 260 icebreaker sweater sometimes just a tshirt). Any imput would be appreciated. Thanks guys.

Responded on

You'll need a Large, to fit your sleeve and torso length. Depending on your build it might be a tad baggy, but these have a slim cut to them.

Responded on

Echoing Ryan, you definitely want a large.

Is there a different in the fit between the hooded gamma mx and the gamma mx jacket? I tried on both and the hooded seemed a little bigger/roomier.

Responded on

The Gamma MX Hoody is just a touch roomier, and has an extra 1.5 inches in the length. Plus, Hoods RULE

Does the hoody part have adjusting straps on the back for when you dont have your helmet on?
Thanks.

Responded on

Todd,
THe Gamma MX is the 2 way adjustable hood. So it has the adjusters that cinch around your face, and the back adjuster (like you have mentioned) that tightens the hood around your bean (like a baseball cap). Be aware that the hood is very large, but you can cinch it down quite a bit when you dont have a helmet on.
Hope this helps

Does anyone know how this compares to the Mountain Hardwear Dragon jacket? They both are hooded softshells and both weigh practically the same amount.

Best Answer Responded on

The Gamma MX uses a stretch woven face fabric with a light fleece laminated to the inside, where as the Dragon uses Windstopper. You'll get quite a bit more breathability and stretch from the Gamma MX, and a bit more weather protection from the Windstopper membrane. A closer comparison to the MH jacket is the Venta from Arc'teryx. I've used both Arc'teryx jackets, and the Venta (windstopper) is great for cold weather, but I find I pull out the Gamma MX way more often throughout the year.

Responded on

Thanks a lot for the response. I already own the Venta AR and really love it, but need a softshell with a hood for a climb that's coming up. Sounds like the Dragon might be the way to go for this particular adventure. Thanks again!

Responded on

I'm 5'8" 140lbs. I have a Small Gamma LT and a Medium Gamma AR. I can't fit much more than a base layer under the small. It gets a bit too restrictive with something like a fleece under the small. The Medium is a bit baggy without a mid-weight layer under it but it still fits well on it's own. I plan on getting a Small MX when the Red comes back in stock.

Responded on

Definitely small. I am 5'7, 160lbs, 38 chest, and the small fits me perfectly. The amazing thing is that it is snug with just a t-shirt, but I can also easily get 2 base layers and a light fleece under it. Great design.

Posted on

So is it just me or does the jacket version of the Gamma MX have a shorter cut than the rest of Arc's jackets? I have the Atom Hoody, and the Alpha SV. They all have the drop back hem. I'm wondering, does the hooded version of the Gamma have this feature? I just feel like its pointless for a jacket that is 98% windroof to be so short. Don't get me wrong, I realize it is for climbing with a harness, but I am looking for an all around jacket for Backpacking, Skiing, etc.. So if the Hooded version has this, I am definitely sold, because this is an amazing softshell.

Thanks, Aaron

The Gamma MX hoody does have a longer bottom hem, and drop back, than the jacket version...

Good lightweight jacket

This is a good jacket. It is quite a bit lighter/thinner than I was expecting, though it is warm for it's weight.

I've used the jacket xc skiing in Maine in single digits, only atop a thick baselayer and it is the perfect temperature for that high-level of activity--not too hot or too cold.

The hood is a great bonus, easily adjustable and well-constructed.

In my opinion this jacket is a bit overpriced, but I do like it and I'm sure I will not be needing another one for at least a decade.

Posted on

I'm interested in this softshell, but wondering if it is asking too much to backcountry ski, resort ski, rock and ice climb. Would this jacket be better than going with a top o the line hardshell like the marmot exum/troll wall, both of which I already have, or would they breathe better...due to the enormous pit zips.

Responded on

In my view, this jacket is a little bit too lightweight for resort skiing. I just purchased it this week and have been wearing it in 30 degree weather with an R1 fleece underneath around town (not yet for any athletic endeavours). I would think you'd want a shell over it to help block the wind.

Responded on

This is a great jacket, but personally, I prefer a hardshell when I am on the slopes. The Gamma MX is water-resistant (but not waterproof) so in prolonged rain or wet snow it won't keep you completely dry. It is on the shorter side, and has no powder skirt. It is more of an athletic cut, so there's not a whole lot of room to layer underneath it. It blocks most (but not all) of the wind, so lift rides can get chilly. It can be used as a layering piece, but I would use it more as a midlayer (particularly if it's wet, windy, or bitterly cold).

But I still love this jacket (even though I don't routinely use it as an outer layer on the slopes). It breathes really well, provides decent warmth on mildly cold days, is well-made, and has a very useful pocket configuration. It's great for most aerobic outdoor activities, and would likely be good for climbing (especially since it is fairly fitted). But if I were going skiing/boarding with it, I would be sure to also have access to my hardshell.

Best Answer Responded on

I've used my Gamma MX for all these things (and more). Of course, anytime you want one piece of gear to cover all conditions, something won't be quite ultimate. That being said, I've never worn another jacket that is as versatile (I've been wearing the Gamma MX for 8 years). If you already have a hardshell, put it in your pack for the really cold resort days, when the MX works great as a layer. You'll get more use from this than most any other gear you own.

The go-to ski touring jacket

Unless there is heavy wet snow or (the horror!) rain, this is the outer layer that goes in my back for nearly every activity. Overall a wonderful jacket with a few downsides. In the temperate northwest, I've found this jacket a bit too warm to skin in (but when the temps dip into the 15 or below range, it's ideal for that purpose), so mainly this is the layer I throw on for the down.

Pluses:
- Sheds water remarkably well while being far more breathable than a hardshell
- Micro-fleece interior adds a bit, but not too much, warmth
- Mesh-backed pockets allow for a bit of venting
- Simple and clean

Minuses:
- Arms are a bit on the long side (I'm a shorter dude)
- The hood is helmet compatible, but maybe a bit of overkill (pretty huge)
- Non-adjustable cuffs (I think this is fine, but you might not)
-Pricey!
