Meet the ALTIOR Core Tee—your new everyday essential.
This isn’t just any tee; it’s a game-changer for your daily wear. Crafted from 240 GSM 100% combed ring-spun cotton, the ALTIOR Core Tee offers a luxuriously soft touch with remarkable durability. Whether you’re heading to the gym, running errands, or enjoying a cozy night in, this tee adapts to your lifestyle seamlessly.
The ALTIOR Relaxed Fit provides a flattering silhouette with a slightly dropped shoulder and controlled sleeve volume. You’ll appreciate its thoughtful design—a clean, straight body that strikes the perfect balance between comfort and style. It’s relaxed without being overly baggy.
Plus, the structured 1×1 fine-rib signature collar adds a refined touch, while reinforced shoulder construction and double-needle hems ensure long-lasting quality. With the added benefit of a Bio Wash + Silicone Soft Finish, this tee feels great against your skin.
Experience the Core Tee—one tee that fits perfectly into every day, everywhere.
Cut in the ALTIOR Relaxed Fit — a slightly dropped shoulder, clean straight body and considered length, relaxed without tipping into oversized. Use the fit finder above for a size based on your own measurements, and size down if you prefer a closer fit.

Tap a swatch to see it. Whichever you pick here is what lands in your bag.
240 GSM, with AeroScale™ micro-holes that move air through the fabric instead of around it.
The scale-like inner face keeps the knit off the skin, so it holds a clean line down the body.
Ribbed, elastane-backed. It sat right at 8am; it sits right at 8pm.
50+ washes tested. Colour holds. Structure holds.
Ribbed at 300 GSM — heavier than the fabric it sits on, on purpose. A 1×1 rib knit, self-fabric bound rather than trimmed separately, so there is no seam edge to peel or curl. It holds its round through 50+ washes, the same round it had on day one.
Five places a t-shirt fails first, and what was specified at each one.
The back neck seam is taped shoulder to shoulder in the same fabric — not visible from the front, and the reason the collar still sits flat a year in.
Structure and breathability are supposed to be a trade-off — heavy fabric traps heat, light fabric loses shape. Altior AeroScale™ runs a micro-hole structure through the knit, so air passes through the fabric instead of sitting in it. The outer surface keeps the clean, substantial look of a heavyweight tee; the scale-like inside is what keeps the heat and the cling off your skin.
Heavy enough to hold structure through movement, heat, and a full day of wear.
A clean heavyweight surface outside. A scale-like, airflow-friendly one inside.
In the body of the fabric. Cotton, and nothing standing in for it.
Fabric weight in your size — XS
1.2× the fabric of a regular tee in XS.
That extra fabric is what holds the shape. It falls straight instead of clinging when it's hot, or collapsing after a wash.
Weight varies about 5% per batch.
None of them are visible in the finished tee. All of them are the reason it still looks like this after the fiftieth wash.
Most tees are judged in the trial room — soft, light, easy for an hour. This one is judged across a working day.
Wash twelve looks like wash two.
Rated for 50+ cold washes, hang dried. The hand generally improves around wash five.
Most tees are 160 GSM. This one isn't.
Most mills chase a heavier number by tightening the knit — past 200 GSM that makes a tee denser, stiffer, and hotter. AeroScale™ opens the structure instead: a field of micro-holes runs right through the fabric, so the paths air moves along stay open at 240 GSM.
The ALTIOR Standard
Not a slogan — the checklist every Core Tee is actually built against before it ships.
240 GSM combed ring-spun cotton. Weighed, not assumed.
300 GSM ribbed knit, self-fabric bound.
Double-needle stitched sleeves and hem.
Rated and tested past 50 washes.
You are moving between a call, a dinner and a flight this week. The last thing that should ask for your attention is a tee.
