ATMOS LT Baselayer Undershirt v2 Review

The guys over at Ministry of Supply gave me a heads up a while ago about the upcoming release of the updated version of their Atmos LT baselayer undershirt.

I got the chance to check it out before today’s release, and have provided some initial thoughts below.

ATMOS LT Baselayer Undershirt Review

Here are my initial thoughts after wearing the Atmos LT v2 for a few days.


Really well done, and pretty spot on. If I were to change anything, it would be to make it a little longer.

The stretch does help in keeping the shirt fall a little further down over my hips, keeping it in place pretty respectably.


Rules to wearing undershirts

I couldn’t tell if the fabric was pre-shrunk or not, so I’ll have to check back with my gear now that it’s been washed to see if it lost any length after washing and drying.


A technically impressive fabric construction with the variable knitting.

From a geek-out perspective, I think it’s pretty cool.

Curious if the ribbed trim pieces on the sleeves and bottom are actually separate pieces attached to the body of the shirt? Or, if those are part of the body fabric, with a different knitting pattern, then folded over.

It’s hard to tell, but it’s well done.


Is too shallow. I had one button undone on my shirt when testing, and my Atmos v2 was still showing :(


Overall, I’m rather pleased with the feel of this cotton/polyamide blend.

I think the only thing I can “sense” on my body is the air vents. Because those areas are knitted differently, I actually feel them on my body.

It’s the slightest difference between me noticing and not noticing the undershirt when I’m wearing it.

Keep in mind, these are micro-nuances I notice that others may not pick-up on.


I think it’s a great weight for a t-shirt, and a bit heavy for an undershirt.

But, the blend and ventilation parts definitely keep the Atmos v2 wearing a whole lot cooler than many other 180gsm tees/undershirts I’ve tried.

I would definitely wear this as a t-shirt under a blazer, because it looks really nice and fits well.


I still think this is a nice & creative element to an undershirt or t-shirt.

Whether or not it makes sweating through to your outside shirt a more pronounced issue is something that would have to be tested.

I understand that the ventilation panels are there to keep you cooler, but I’m not sure if that alone would keep a guy from sweating.


I’m a big fan of cotton/synthetic blends that are done right.

I believe the Atmos v2 blend is done right. The great things about these blends is that they combine absorbing, wicking, and fast drying.

I think that’s a great combination in an undershirt, so real good job here.


This is a very nice undershirt.

It’s not inexpensive, but for what they’ve done with it, I think the price is in line with the amount of detail put into the Atmos v2 undershirt.



How to wear undershirts

  1. Any update on the ventilation testing? Does the shirt work like a wicking shirt where the sweat just ends up on the outer shirt? Or is there a good balance of absorbing and drying without just moving the sweat to your outer shirt?

    • heya chad – this atmos has a good middle ground of cotton and nylon (polyamide) blend fibers, so it should perform reasonably well in preventing a lot of sweat through. the weight is on the heavy side (for me), and the v-neck is too shallow, so i really don’t wear this shirt.

      plus, i don’t sweat very much in general, so i can’t effectively test this shirt’s sweat-through performance — or lack there of.

      Unless specifically designed to prevent sweat-through, most any wicking undershirt/shirt will push sweat to the fabric’s outer surface. the degree of the amount of sweat through is predicated on a bunch of different factors.

      i just wrote an article about a new performance shirt using 37.5 technology from cocona that provides some great information about wicking:

      i have not tried that vaporactive shirt yet, but i would not likely wear it as a daily-wear undershirt, because it’s designed more for sports than it is for undershirt-wear.

      the fabric that i believe has the best hand-feel combined with great moisture management is tencel. it’s like a luxury version of viscose, but the core fiber is called lyocell.

      all that said, if you sweat a lot, you may need an undershirt that prevents sweat through, and if you need something like that, i’d recommend:
      1. sutran (all over protection)
      2. nanodri (all over protection)
      3. thompson tee (underarm protection only)

      let me know how it goes!
