Marmot ROM Jacket review

I’ve been putting this jacket through the paces for the last couple months and feel like I have a good handle on how it performs etc.

First, I should remind you that this was a jacket I bought after rather extensive research and experimentation with a specific goal in mind.

Here’s what I wanted:

A VERY breathable, light, windproof jacket with a hood that does well over a helmet or without a helmet.

I was looking for a jacket to solve a problem. I sweat a lot and generate a lot of heat when I’m ski touring. Last year I was doing laps in nothing but a Capaline base layer soaked in sweat. This becomes a problem when the wind kicks up, or when you stop moving. I found my self stopping to add and drop layers and getting cold as soon as I stop. I wanted a jacket that would keep the wind off but also keep me from getting too hot.

From what I read the ROM looked to be the best piece for the job/price. It doesn’t have a high-tech membrane, I’ve got other jackets for that, which keeps the price down.


I’m 6’3″ and 200 lbs, with a long torso and a large fits me very well. I’ve got pleanty of room for layering under it (though on tours I put my insulation on over it rather than loose all the heat) but the fit is athletic enough for trail running with just a light tee-shirt underneath.

I’ve taken the ROM on several ski tours, trail runs, and bike commutes and I’m convinced that I found the perfect jacket for my backcountry travel system.

Here how the jacket works for me on a tour:
– I layer the ROM with a light base layer, usually a Patagonia Capiline 1 or 2, and pack a Patagonia Nano-puff in my backpack.
– On the up I regulate heat by putting the hood up or down, opening and closing the hand-warmer pockets (mesh on the inside, with an interesting almost duct-like pocket design makes them as effective as any pit zip I’ve ever used), and taking off my gloves. I’ve only had to unzip the ROM about 1/3 of the way, while others have had to stop and drop a layer, but most of the time I’m zipped the whole way up. An “up” scenario, where the ROM really stands out is the classic Wasatch approach: The parking lot was chilly so everyone had on a few layers – I was just in the ROM and a Cap 2 base layer, we hit hte skin track and everyone had to stop and drop a layer. As we worked our way up a protected face all the jackets but mine went into the packs, I just unzipped my pockets and took off the hood. When we gained the ridge, just below the summit we got hit by gusts of wind – I closed the windward pocket and flipped up the hood and kept rolling while everyone shivered while fumbling for layers or just gutting out the cold gale.
– At the transitions, if they are quick I’ll just put up the hood and keep moving, If we are standing around I’ll toss on my Nano-puff (I’ll pop it back into the pack for the down as I usually get pretty warm on the down too- the nano puff is a great piece but I think the Arc’teryx Atom LT with a hood and full zip would be a bit better).

As far as wind proofing – bike commuting on freezing mornings is the key test and the long arms and torso make this a great jacket for that – though the tail is cut long it’s not quite long enough to be the perfect bike jacket, but that’s not what I’m looking for. The ROM does shut down the wind though and that’s what I’m looking for.

On trail runs where my pace varies I love the jacket – especially because my trail running usually has a solid amount of scrambling and 3rd, 4th, and maybe 5th class terrain where I have to slow down or risk a very exciting ride. For these sections I put on my light gloves, cinch up the hood and close the pockets – and I’m warm. Then when I’m back up to speed I open everything up and I’m good.

The ROM isn’t waterproof, though it manages moisture well. This is not the jacket you want for real rain or wet snow, but I can count the days in the last decade here in Utah where I’ve needed that. If the weather is worth touring in the ROM should take care of you.
