For the HYROX SkiErg, wear a fitted sleeveless race singlet or a short-sleeve technical tee with a clean shoulder cut, so nothing bunches at the armpit or drags during the repeated overhead-to-hip pull. The safe choice is minimal shoulder fabric that moves with the stroke, never a loose long-sleeve or wide-cut vest that catches at the top of each rep.
- The SkiErg is the first station: 1000m of double-arm pulling from overhead down to the hips, repeated hundreds of times.
- Fabric that bunches at the shoulder or armpit interrupts the stroke and chafes over 1000m.
- In THETA's coaching data, a fitted singlet or precision-cut tee removes almost all sleeve interference on the SkiErg.
Why do sleeves get in the way on the SkiErg?
The gun goes, you sprint to the first station, and your arms are straight overhead on the handles within seconds. From there the stroke drives down to your hips and back up, and it repeats that arc for the full 1000m while your heart rate climbs. A loose or long sleeve bunches under the armpit at the top of each pull and can catch as your arms come down, breaking rhythm on a station where rhythm is everything. Wide-cut vests gape at the armhole and hand you the same problem. Overhead is the enemy of any excess shoulder fabric, which is why sleeve design matters here more than almost anywhere else.
The mechanism is a fabric geometry problem. When your arm is by your side, a sleeve hangs long and there is slack in the fabric across the shoulder. Raise that arm fully overhead and the shortest distance from collar to cuff runs straight up the outside of the arm, so all that slack has to go somewhere, and it gathers into a fold right at the armpit. On a single rep it is nothing. On the SkiErg you make that same movement several hundred times in a row, and the fold rubs the same soft, sweaty patch of skin under the arm on every one of them. That is how a top that felt fine trying it on becomes a raw line by the time you sprint off to the sled. A close armhole or no sleeve at all removes the slack, so there is nothing to gather and nothing to rub.
What top works best for the SkiErg?
A race singlet is the cleanest option because it removes sleeve fabric entirely and keeps a tight armhole, so nothing bunches overhead. THETA's Race Singlet is ultra-light with laser-cut airflow and reinforced shoulders, giving a secure shoulder line through the repeated pull. If you prefer sleeves, the Tech T-Shirt Race Team v2 is precision cut per size with open ventilation, so the sleeve sits close and does not gape at the armpit. Both keep the shoulder area clean for the overhead phase of the stroke.
| Top type | SkiErg behaviour | Verdict |
|---|---|---|
| Race singlet | No sleeve, tight armhole | Best, nothing to catch |
| Precision-cut tech tee | Close sleeve, no gape | Good if you want sleeves |
| Tech tank | Open, airy, fitted armhole | Good, maximal airflow |
| Loose gym vest | Gapes at armhole | Avoid, catches overhead |
| Long-sleeve top | Bunches at armpit | Avoid on race day |
"The SkiErg is your first station and it sets your rhythm for the whole race. If your sleeve is catching overhead on rep three, you've handed away time before you've even started," says the THETA coaching team.
How do you set up your top for the pull?
Get the shoulder line sorted in the pen, before your hands ever touch the handles.
- Choose a singlet or precision-cut tee with a close, non-gaping armhole.
- Check the shoulder stays flat when you reach both arms overhead.
- Confirm the sleeve or armhole does not bunch at the armpit at full stretch.
- Make sure your race belt sits at the waist, clear of the pull arc.
- Test the full overhead-to-hip stroke soaked to confirm no cling or catch.
Does a tank beat a tee for the SkiErg?
A tank or singlet gives the most freedom overhead because there is no sleeve at all, and it maximises cooling on a station that spikes your heart rate fast at the very start of the race. THETA's Tech Tank Race Team v2 uses the same fabric system as the tee and stays open and airy through race sims, so it is a strong SkiErg choice. A tee is fine if it is precision cut and close at the sleeve, but if sleeve interference is what worries you as you reach overhead on rep one, a tank or singlet removes the variable entirely.
Why the first station is the one to get right
It is tempting to treat the SkiErg as just one of eight stations, but its position at the very front of the race gives it outsized weight in a kit decision. You reach it cold, on adrenaline, with a fresh heart rate spiking from zero to near maximal in the first minute. That spike is the moment your whole race finds its rhythm or does not, and it is also the moment you are least forgiving of a distraction. A sleeve catching overhead on rep three does two things at once. It costs you the few seconds of the catch itself, and it plants a small worry that follows you to the next station, so you are half-thinking about your top when you should be settling into the sled.
There is also a knock-on into the run legs. The SkiErg leaves your shoulders and lats pumped and your top soaked with the first heavy sweat of the day. If that top is going to cling, this is where it starts, and it will keep clinging through the run to the sled push and beyond. Getting the shoulder line right at station one, then, is not only about the SkiErg. It sets the tone for how the top behaves for the next hour. Prove the overhead reach soaked in a simulation, from a cold start if you can, so the version of the top you test is the version you meet at 60 seconds into the race.
Common questions
What should I wear for the HYROX SkiErg?
Wear a fitted race singlet or a precision-cut short-sleeve technical tee with a clean shoulder line. The goal is minimal shoulder fabric that does not bunch at the armpit during the repeated overhead-to-hip pull.
Why do sleeves interfere with the SkiErg stroke?
The stroke goes from overhead to the hips repeatedly, and loose or long sleeves bunch under the armpit at the top and can catch on the way down. That breaks the rhythm the SkiErg depends on and adds chafe over 1000m.
Is a singlet or a t-shirt better for the SkiErg?
A singlet is cleanest because it removes sleeve fabric and keeps a tight armhole overhead. A precision-cut tee like the Tech T-Shirt Race Team v2 works if you want sleeves, as it sits close and does not gape.
Can I wear a tank for the SkiErg?
Yes, a tank such as the Tech Tank Race Team v2 gives full overhead freedom and maximum cooling. It uses the same fabric system as the tee and stays open and airy through race sims.
Should I avoid long sleeves on race day?
For the SkiErg, yes, long sleeves bunch at the armpit and interfere with the overhead pull. If you need warmth beforehand, use a shed layer in the start pen and race in a sleeveless or short-sleeve top.
Does a wet top affect the SkiErg?
A soaked loose top can cling and drag overhead, while a vented, fitted top stays lighter and keeps its shape. THETA's fabric is built not to go heavy when soaked, which keeps the stroke clean even later in the race.
Where should my race belt sit for the SkiErg?
Keep the belt at your waist, clear of the pull arc, so the bib and buckle never interfere with your hands or the handles. Set its tension before your wave so nothing needs adjusting during the stroke.
