Perspectives on the sport. Written by our Athletes, and our Founders.
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...
Race fabric is stripped to the minimum weight that still holds up, prioritising airflow, fast drying and staying light when soaked over comfort and hand-feel, while everyday gym fabric carries a little...
Shoulder-neck seams fail because they sit exactly where a top is stretched hardest, over the shoulder when you extend overhead on wall balls and the SkiErg, and where sweat and repeated washing...
A short disappears under fatigue when it stops giving your brain anything to flag. The feeling is not really about the fabric, it is about attention: a tired brain hunts for problems,...
Waistbands roll and dig because a thin, single-layer band with no structure folds over when your torso bends and cuts in when it is stretched too far. A good waistband spreads pressure...
A T-shirt goes through 20-plus fabric revisions when it is developed through a real testing loop, athletes wear each prototype in hard training and racing, report what fails or gets in the...
Open ventilation construction is a fabric build where the gaps that let air through are woven into the knit itself, not punched, printed or sprayed on afterwards. It stays airy because the...
Cheap training tees stretch out after a month because their fabric has too little elastane to recover its shape, weak or stitched seams that loosen under load, and low-quality knits that deform...
Fused seams beat stitched seams under abrasion because they bond the fabric into a flat, continuous join with no exposed thread to wear through and no needle holes to tear along, so...
Elastane percentage changes how kit moves with you because elastane is the stretch-and-recovery fibre, so more of it means more give and a faster snap back to shape, while too much can...
Breathability is a fabric's ability to move heat and water vapour off the skin, and it works through two routes, air passing through the fabric and sweat evaporating from its surface. HYROX...
During repeated high-output work, moisture adds weight and, more importantly, changes how a fabric drapes. Dry, a top hangs off you and moves as you move. Soaked, an absorbent fabric sags, stiffens...
A fitted chest and relaxed stomach cut performs better because the top stays close where it needs to move with you, across the chest and shoulders, while leaving room over the stomach...
Heat-sealed construction removes fabric failure points by bonding pieces together with heat and pressure instead of a line of stitching, so there are no needle holes, no thread to snap and no...
Ventilation holes get laser-cut instead of sewn because a laser melts and seals the fabric edge as it cuts, creating a clean hole that will not fray, unravel or need a stitched...
