User Review: Arc'teryx Men's Gamma MX Jacket
Price Paid: $300 from Massey's Outfitters on Amazon.com
As much as I wanted to get the Sky Blue Ray color of this jacket, I couldn't bring myself to wear it everyday. Instead, I chose a more muted option; the Nightshade, and I've gotta say that it works rather well. The hint of blue on the access pockets really sets it off.
The fabric is Fortius 2.0, sorry Polartec, seems you've been replaced, but it's OK. Fortius does the job without compromise. I have a Gamma AR as well and you can tell the difference between the two.
In comparison, you can't go wrong with any of the Gamma models, but while the SV (discontinued) and AR models would be built solely for warmth and durability, the MX would be built for comparable warmth and flexibility. It seems to be more in the stretchy category over the AR and SV, so it fits in the aerobic category. I can use it for everything and that works for me.
Granted, my Marmot Sharp Point remains my staple or go-to shell, but nevertheless the MX is a great piece. It's articulated in cut, with arms that are made for movement with good length. Not too short or long, and just the right torso length. Sizes are true.
I'm just glad that I had the extra $300 to grab one.
Yep, it's pricey, but look at it this way, you're gonna get 15+ years out of each shell if you take care of it.
Be confident that this is a good investment.
