Ultra X
Tee

Built For Distance · Flag At The Hem
$58.00

The one built for the distance the others are not. A nylon and spandex mesh that stretches, holds its shape and dries as fast as anything we make. Notch collar, the mark on the left chest, and the flag stitched at the hem. It is the shirt that goes to the start line of something long.

Fabric
A nylon and spandex performance mesh. Nylon is what makes it hard wearing over long mileage rather than just soft in the hand, and the spandex is why it still fits the same way after a season of it.

The Ultra X Tee

Named For
The Distance.

Most training shirts are judged on an hour. This one gets judged somewhere around hour four, when a seam starts to matter and a fabric that has stretched out of shape becomes the only thing you can think about. Nylon and spandex, because that is what survives it.

Every Detail Has A Job

The Details You Notice At Hour Four.

01

Nylon, Not Just Soft

Cotton feels better in the shop. Nylon is what is still holding its shape after a season of long efforts, a hydration vest rubbing the shoulders, and more washes than you bothered counting. This one is built for the second year, not the first wear.

02

The Notch Collar

Not a full crew. The neck opens into a short notch, which is the difference between a collar that sits and one that chokes when you drop your chin for four hours. Small detail, and the sort you only notice when it is missing.

03

The Flag At The Hem

Stitched low on the front hem rather than printed across the chest. You see it when you look down at your own shirt, which is roughly the only person it is there for.

04

Shape Retention

The spandex is not there to make it feel stretchy on the hanger. It is there so the shirt you pull on in month nine still hangs the way it did in week one, rather than going long and loose at the hem.

Where It Earns It

Trail, And The Long Way Round

Crossing the bridge in the Ultra X Tee
Off Road

On The Trail

Nylon takes a branch and a pack strap better than a soft knit does, which is the whole reason it is the fabric here.

Hours In

Long Days

Vest on, hours down, and the shoulders still sitting where they started. This is the part of the run that decides whether a shirt was any good.

Questions, Answered

How does it fit?
True to size. For reference, our model is 6'1" and 212 lb with a 32 to 34 inch waist, and he wears an XL in tops. Check the size chart for exact measurements, and if you are between sizes, size up for room rather than down.
Which tee do I actually want?
The Ultra X is the distance shirt: nylon and spandex, built to survive a vest and a season of long efforts. The Drift is the lightest, a mesh for pure heat. The Ascend is a textured knit for general training. The Raider is cotton, modal and spandex and goes everywhere. If the day is measured in hours rather than minutes, this is the one.
Does it work under a hydration vest?
That is a large part of why it is nylon. A soft knit pills and thins where a pack strap sits on the shoulder. Nylon takes that rubbing considerably better, which is what you want from the shirt you wear for the longest days.
Does the size chart change with the colour?
Yes, and this page swaps it for you. Each colourway has its own chart, and the Size Chart button always opens the one matching the colour you have selected.
Is it fitted or relaxed?
Tailored for movement rather than boxy. If you want a genuinely relaxed drape, size up or look at The Oversize Tee instead.
What is the notch collar?
Instead of a closed crew neck, the collar opens into a short notch at the front. It sits lower on the throat, which matters when your chin is down for hours rather than minutes.
How do I wash them?
Cold water, tumble dry low or air dry. Heat is what kills nylon and the stretch in it, so keep it off the hot setting and this shirt will outlast several of the ones bought after it.
What is it made of?
A nylon and spandex performance mesh. The percentage split currently listed in our own description does not add up, so rather than repeat a number that cannot be right, the fibres are named here without one. It will be corrected.
