Ten Thousand Seamless Shirt Review: No Seams, All Performance

We put this technical training top through the ringer to see if it could live up to its challenging moniker.

Cotton is dead. At least, in the fitness realm, anyway. Today's ready-to-go workout apparel is lightweight, highly engineered and designed to keep you focused on your reps rather than your sweat or stink.

And as technology advances and new manufacturing methods arise, every new product takes us further away from those raggedy college fraternity cut-offs (don't lie, we all worked out in them). One recent example of cutting-edge workout gear is Ten Thousand's Seamless Shirt. With body-mapped mesh for breathability and no "seams" for added comfort (more on that later), this latest training top combines a weight rack full of innovation into one impressive garment.

But it takes just one look at the new Seamless Shirt to notice the raglan "stitching" around the sleeves, as well as the collar, which had us curious if the "seamless" moniker was true to its word or just a marketing ploy. To test the comfort, as well as the technical features, I dawned this T-shirt in a variety of environments. From the gym, to the streets, the softball fields and beyond, I wanted to see if this top could take the top spot in our closet. Here's what I learned.

What's Good About the Ten Thousand Seamless Shirt

Exceptional comfort and performance thanks to thoughtful engineering

Let's get this out of the way, first. While there are "seams" present, they're not like the typical seams on your favorite pocket tee. According to the brand, the entire shirt is knit in a single pass, and the raglan stitches serve as an engineered feature for comfort and maneuverability rather than a joint.

When I received the Seamless Shirt, this was one of the first components investigated. While you can visibly see the seams, which begs the question of what a "seamless" shirt truly is, the raglan is lay-flat and definitely feels more comfortable than other shirt designs. No scrunching or balling up, even during high-intensity exercises.

In terms of the other features built into the apparel piece, it's clear Ten Thousand knows how to sew some serious workout gear. The body-mapped mesh kept me cool and dry throughout training, and the silver ion anti-odor treatment helped block any developing funk. This was particularly beneficial on some nights when I had to travel to the local grocery store post-workout for last-minute dinner ingredients (nobody wants to stink up the joint).

The Seamless Shirt fits as good as it looks

While some workout shirts boast a plethora of technical features aimed at improving your workouts, they can easily miss the most important feature of clothing — fit. And as a taller athlete, I've run into a few examples where the length was less than ideal. Thankfully, the Seamless Shirt provided plenty of length that rested just below the hips. The sleeves weren't constrictive, either, which left me oftentimes grabbing this top for non-training days as well.

What's Less Than Ideal About the Ten Thousand Seamless Shirt

This top is lightweight, but not ultra-lightweight

I definitely admired how lightweight the Seamless Shirt felt on the skin, which helped in terms of motivation to stay mobile in training. However, I did test this top as an undershirt during a few league softball games, which is where I unearthed this discovery.

While comfortable and versatile, the midweight knit fabric was a little heavy when compared to other tops in my closet. If you're someone that wants a t-shirt that feels like it's barely there, there are other lighter options out there. For example, the Better Than Naked Tee from The North Face provides exceptional breathability in a lightweight profile, making it an excellent pick for humid runs or other training disciplines.

The Seamless Shirt retains its shape well, which might be unflattering for some

Another key feature sewn into the Seamless Shirt is its shape retention engineering. While some shirts can stretch or get weighed down as you progress through intense workouts, the Seamless Shirt is designed to maintain its profile during high sweat sessions. This was a great component, but I realized that the benefit was a result of proper fitting.

I filled out the shirt evenly through the chest and abdomen, but every body type is different. If you have skinnier shoulders or typically wear looser fitting tops, the shape retention could leave you with a boxier silhouette. Be sure to read the size guide prior to purchase.

Ten Thousand Seamless Shirt: The Verdict

With training-specific specs aplenty, the Seamless Shirt is another great addition to the Ten Thousand lineup. While the raglan stitching may test your definition of "seamless," the comfort and versatility of this impressive top is definitely sewn in successfully. At less than $65, the Seamless Shirt is on-par with other technical training tops, and after wearing it just once, you'll have no problem getting your money's worth. Find your size, choose your color, and pull the thread on this versatile, well-designed t-shirt.
