Perspectives on the sport. Written by our Athletes, and our Founders.
HYROX training punishes kit harder than almost any other training, subjecting it to sled friction, barbell abrasion, deep repeated lunges, high-volume sweat and frequent washing. Over a training block that combination wears...
Two race seasons of testing teach one thing above all: fabric fails predictably. It goes at the seams before the panels, at friction points before flat areas, and it always shows its...
Fabric choice affects chafe over 8 kilometres of HYROX running because chafe is caused by repeated friction, made worse by wet, heavy, clinging fabric and rough seams. A fabric that wicks sweat,...
Technical kit costs more than cotton because it is engineered rather than just cut and sewn: performance synthetics, laser-cut or woven ventilation, heat-sealed and reinforced seams, tuned stretch blends and rounds of...
Seamless construction helps under load because it removes the raised stitched joins that dig in, chafe and become failure points when a garment is stretched hard, pressed against by a barbell or...
Fabric recovery determines whether kit keeps its shape because recovery is the fabric's ability to return to its original dimensions after being stretched. Kit with strong recovery snaps back after every lunge,...
Barbell and sled contact points need different seams because they stress kit in different ways: a barbell across the back or shoulders presses and abrades a static point under heavy load, while...
Modified polyester is standard polyester engineered to remove excess weight and add function, so the base fabric is stripped back as light as it can go while keeping the strength, wicking and...
Fabric blends balance softness, stretch and recovery through a single number: the ratio of base fibre to elastane. Polyester or polyamide carries strength, structure and moisture handling; elastane adds the stretch and...
Ultra-light race kit reinforces only where it fails first because adding strength everywhere would make the garment heavier and hotter, so the smart approach is to keep the whole piece light and...
A fabric dries quickly when it spreads the water it holds over the largest possible surface area, so more of that moisture meets moving air at once. Evaporation happens at the surface,...
Some seams chafe and others do not because of where the seam sits, how it is constructed and how much it moves against your skin. A thick, raised, stitched seam placed in...
Race tops reinforce the hem because the hem is where ultra-light race fabric fails first: it is gripped, tugged and rolled every time you pull it down after overhead work, and it...
Precision cutting per size means each size is cut to its own pattern rather than simply scaling one shape up or down, so the fit stays true across the whole size range....
Technical fabrics hold odour because synthetic fibres like polyester are oil-loving, so they trap skin oils and the bacteria that feed on them, and their smooth, non-absorbent surface lets those bacteria cling...
Ventilation placement follows your sweat map: the body sweats most on the upper back, chest, underarms and lower back, so well-designed kit concentrates airflow there rather than spreading it evenly. Placing laser-cut...
