Size Guides

Cut to disappear.

The right fit feels like nothing at all. Here's how to find it.

How it fits

Compression isn't sized like a t-shirt.

Our base layers are designed to sit close to the body — closer than what you'd wear to the gym, closer than your everyday tee. That's the point. Compression works because the fabric stays in contact with your skin, smoothing where you want it to.

But that doesn't mean it should feel tight. A good Susuro fit feels firm at first, then settles. By the third wear, you stop noticing it's there.

Which fit is yours

Across our line, every piece shares the same sizing logic. Your usual t-shirt size is your starting point.

What changes from one style to the next is how close it sits. Some are cut for an everyday close-but-easy feel. Others run tighter for stronger compression and a more sculpted line.

Each product page tells you which side it sits on, so you'll know what to expect before you order. If a style runs tighter, we'll say so — and the move is simple: size up if you'd rather have more room.

How to measure

You'll need a soft tape measure and a mirror. Measure on bare skin or over a thin shirt — never over a jacket or sweater. Stand relaxed, breathe normally, and keep the tape level.

1 · Chest. Wrap the tape under your arms, across the fullest part of yourchest. Keep it snug but not tight — you should be able to slide a finger under the tape comfortably.

2 · Waist. Find your natural waistline, usually about an inch above your belly button. Wrap the tape level all the way around, and don't suck in.

3 · Length. Lay one of your favorite tanks flat and measure from the top of the shoulder seam to the hem. That's the length you're used to wearing.

Once you have your numbers, head back to any product page. The Chest measurement is the one to match against the size chart.

Fit FAQ

How tight should it feel?

Firm, not restrictive. You should feel the support but breathe normally and move freely. If it's a struggle to pull on, size up.

Will it stretch out over time?

A little. The fabric softens about 2-3% after the first few wears, then stays consistent. We make our sizes with that built in.

Can I machine wash it?

Yes. Cold wash, hang or lay flat to dry. Skip the dryer — high heat shortens the life of any compression fabric, ours included.

Why are some styles cut tighter than others?

Different cuts serve different needs. Some are built for everyday wear and a close, comfortable feel. Others are built for stronger compression and a more sculpted line. The product page for each style will tell you which side it sits on. If a tighter fit isn't your thing, sizing up is always an option.

Do you offer larger sizes?

Some of our styles go up to 3XL today, and we're working on extending sizing across the rest of the line. Drop your email at the bottom of any product page to be the first to know when larger sizes launch.

I'm between sizes. Which should I pick?

Go with the smaller for more compression, or size up for ease. Our Size Guarantee means you can swap free if you change your mind — so when in doubt, pick the one that matches the feel you want, not the one you think is "safer."
