Do Marmot Jackets Run Small? (Very Helpful Guide)

Sharing is caring!

The majority of Marmot jackets run true to size, only some run small and a very few runs big.

The jackets that run small, are small & tight mostly in the shoulders, chest, and waist.

But if you size up some jackets that run small like Marmot men’s smokes run jacket then it will get bigger in sleeves than needed.

Still, most of the time the jackets that marmot offers fit perfectly and are just what works best in terms of fitting.

I’ve covered so many brands and their jackets fitting with a very big data set of which jackets run small, big, or are true to size.

And today we will do the same with Marmot jackets along with a really big table consisting of most of the marmot jackets (men’s/women’s) and their fitting recommendation (get a size up or not).

If you’re a Patagonia or Arc’teryx user then you’ll be pleased to know that Marmot jackets run very close to them in terms of sizing.

So you can go for the same size with Marmot that you go with Patagonia and Arc’teryx.

Why Some Marmot Jackets Run Small?

To be clear, I do not know the exact reason. But, after observing marmot jackets that run small is – that they tend to go slimmer in shoulders and chest.

Another common reason for those jackets is the fitting type. To give you a broad understanding with a short description let me tell you the type of fit marmot offers in their jackets.

Marmot offers 4 fits tops: Athletic, semi, regular, and relaxed. Among these 4, jackets are only available in athletic and regular.

Let’s leave the other two and just discuss the jacket fits as it is what the article is about.

Athletic Fit:

Athletic fit features tailored or shaped shoulders and fitted hem. If you go with this fit then you need to be aware that this ain’t the needed room to add the layers without losing mobility.

Marmot Jackets Athletic Fit

In its own nature, it tends to be tighter in the whole body to give you a more slim and shaped fit.

As the name implies, it is recommended that only the person who has an athletic body can consider this fit. Any other person may find it a taut.

Regular Fit

The marmot jackets with this fit are less shaped or tailored and are much roomier than the athletic fit.

Regular Fit Marmot Jackets

This is what I would recommend to most people who want to buy a very comfortable and mobile jacket that does not resist the body’s movement even when adding layers like a thick fleece, heavy sweaters, sweatshirt, etc.

But keep in mind that not every marmot jacket with the relaxed fit is true to size because as you will see in the table mentioned in this post that still there are jackets like Minimalist Component 3-in-1 which runs smaller than what the size chart says and thus it is recommended to go a size up.

This is just an example there are more jackets in both men’s/women’s sections.

However, a very few regular fits also run big like Fordham, Mammoth Parka, etc where some of these are intended to run big which is good however, a very few are good with going a size down, even if you don’t it is not a problem because then the jacket can bear multiple layers both thin and thick.
