The Elevated Tee, Built For How Your Body Actually Fits.
Most t-shirts are cut for an average that doesn't exist. The Cumulus is built to your exact proportions with our SmartFit AI — then cut and sewn in the USA from heavyweight French Terry cotton. You take a 60-second quiz. We ship in 5 days. And the first time you order, the 2-Pack is the easiest way in — two for $69 each instead of $99.

Why switch to the Cumulus
Three Reasons It Becomes The One You Reach For.
Reason 01 — The drape
It's Flattering On Every Build.
Thin tees show every nook and cranny. The Cumulus is cut from heavyweight French Terry that drapes cleanly over your body — skimming where it should, never clinging where it shouldn't.
- Heavyweight French Terry knit
- Drapes over the body, doesn't cling
- Flattering on every build
Reason 02 — The versatility
Sharp Enough To Go Under A Blazer.
The Cumulus has the weight and structure to hold its own in dressier contexts. Layer it under a blazer and it looks intentional — not like you ran out of time.
- Crew neck sits clean under collars
- Structure that holds through the day
- Available in 12 colorways
Reason 03 — The elevated look
The Kind Of Tee That Gets Compliments.
Nothing kills a look faster than a pilling, wrinkly tee with a stretched-out neck. The Cumulus is cut from heavyweight French Terry that holds its shape — made in the USA, shipped in 5 days.
- Cut and sewn in the USA
- Holds its shape, wash after wash
- Resists pilling and stretched-out necks

Rave Reviews From People Who Wear It Daily.
★★★★★
"Best shirts ever! I thought I preferred thin tees until my brother convinced me to try these. The fit is incredible (and forgiving if you go up/down a few lbs). I have 7 shirts in rotation now."
Christopher K · customer since Oct 2021
★★★★★
"These tee shirts are my GO TO! They work great under blazers, sweaters or alone. I frequently get praise on my attire when wearing them. At least a half dozen of my favorite colors in the closet. Well done Sene!"
Chris W · customer since July 2021
★★★★★
"Start to finish, Sene has been amazing! Every customer service interaction was quick, friendly, professional and all promises kept!"

Questions? We've Got Answers.
How does the 2-Pack save me money? +
The Cumulus is $99 as a single. In the 2-Pack you pay $138 for two — that's $69 a shirt, and $60 less than buying them separately.
How does the custom fit work? +
Take a 60-second SmartFit quiz and our AI builds your pattern from your proportions — no measuring tape or tailor required. It's 96% accurate out of the box, and every shirt is cut and sewn to that fit in the USA.
How long until it ships? +
Each pair is made to order in the USA and ships in about 5 business days.
What if the fit isn't right? +
You're covered by a 30-day risk-free guarantee with free alterations and remakes. If it isn't perfect, we'll adjust it or remake a brand-new shirt from scratch — and you get another window to try the new fit.
Can I mix colors across the pair? +
Yes. Choose any two of the 12 colorways — same custom fit on both.
How do I care for it? +
Machine wash cold and tumble dry. The pre-shrunk French Terry keeps its heavyweight drape and shape season after season.
