The name says it all.

What's in a name? Well, with the Outdoor Research Maximus Men's Jacket, pretty much everything. It's a full-blooded alpine workhorse, designed to handle the nastiest weather in the burliest places with the least amount of fuss possible. It's simple, sure, but that doesn't mean it isn't ruggedly built and thoughtfully designed to maximize what it does have. It starts off with a Gore-Tex Pro waterproof and breathable membrane to keep you dry, and accents that with a Gore-Tex Pro Stretch membrane on key points like the elbows, underarms, and hood for comfort and freedom of movement when you're climbing, hiking, or skiing down after. Each and every seam has been taped to ensure complete weather protection, all the zippers are water-resistant, and the stowable hood—it rolls into the collar if you don't want it out—is designed to fit over helmets with ease, and has a wire brim to keep water out of your eyes. It also cinches up with a Halo closure, which seals out weather without blocking your peripheral vision.

The Maximus is designed to be worn under harnesses and packs, so it's no surprise that it has pack- and harness-compatible hand pockets, along with articulated elbows and a Movement-Mirroring stretch design that makes it easy to maneuver in tricky alpine spots. If the sun peeps out and you start getting warm, unzip the underarm-to-hem TorsoFlo vents to get some air moving and grab a quick snack out of one of the Maximus' plethora of pockets. When you're ready to move again, cinch up the hem drawcord, lock down the hook-and-loop cuffs, and boogie up to the summit before the next squall rolls in.

Here's what others have to say...

I've been using an OR Inertia shell in a Large and it is a nice athletic fit for my 6'2" & 200 lb frame.

Is the Maximus sized the same as the Inertia?

Best Answer

The Maximus has a trimmer fit than the Inertia. The Maximus was made with a climbing focus where the Inertia has a more ski focus with its development. So you would still be a large but, it will fit a little smaller so there is no excess fabric kicking around when you are climbing with it. If you sized up to an XL it would fit too big everywhere.

Hey Snokat Al, first off, LOVE the name! Secondly, thanks for the great question. My friend Bill who answered your question at Backcountry nailed it. The Maximus is a trimmer fit. So glad you lik ethe Inertia!

This shell is my favorite jacket for long days on the splitboard. The super tuff goretex pro fabric is surprisingly light, yet keeps you dry and warm when a heavy wet storm hits. For ski touring and splitboarding i think its important to have a lightweight packable jacket you can easily stuff inside your pack, yet you need something that will stand up to the abuse of shredding day in day out.

One of my favorite features on this jacket is the TorsoFlo hem-to-underarm vents. These dump heat and provide air flow unlike any other system i have tried. You can zip your vents down, and buckle the waist strap of your pack under your shell, to eliminate bulk and really cut down on heat build up. Huge vents!

The fit of this jacket was designed around the movement involved in alpine climbing. The articulated arms and under arms keep the jacket in place when moving your hands around for ice climbing or funny snowboard movements. Very nice when your ridding deep snow and cant afford your jacket rising up, leading to your pants filling with snow.
