How Many Wash Cycles Should Training Kit Survive?
Good technical training kit should survive well over a hundred wash cycles with its fabric, fit and ventilation intact, provided you wash it cool and air dry it, because heat and tumble...

Why Do Zips on Training Shorts Fail and What Replaces Them
Zips on training shorts fail because standard sewn-in zips flex, corrode with sweat and snag under the repeated movement of running, lunges and sled work, so the teeth jam or the zip...
What to Wear for Garage-Gym Sessions in the Cold
For cold garage-gym sessions, wear a wicking base layer under an easily removable warm layer such as a ¼-zip or hoodie, so you can strip down as you warm up and cover...
How to Layer for Outdoor Runs Through a UK Winter
To layer for outdoor runs through a UK winter, use a wicking base layer to move sweat, a light insulating mid-layer for warmth, and a wind-resistant outer only when needed, dressing to...
Why Do Training Shorts Bounce and How to Fix It
Training shorts bounce because loaded or unsecured pockets swing with every stride and because a loose, unstructured waistband lets the whole short shift as you move. The fix is flat, secure storage,...
Do You Need Pockets in Your Training Shorts? What Coaches Say
You need pockets in training shorts if you carry a phone, keys or gels through sessions, but they must be flat and secure so they do not bounce or snag during running,...
Why Does the Sled Wreck the Front of Your Shirt?
The sled wrecks the front of your shirt because the sled push forces you into a low, braced position where the fabric across your chest, forearms and hem drags against the sled...
What Does HYROX Training Actually Do to Your Kit?
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...
What 2 Race Seasons of Testing Teaches About Fabric Failure
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...
How Fabric Choice Affects Chafe Over 8 Kilometres of Running
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,...
The Real Reason Technical Kit Costs More Than Cotton
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...
Why Seamless Construction Helps Under Load
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...
How Fabric Recovery Determines Whether Kit Keeps Its Shape
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,...
Why Do Barbell and Sled Contact Points Need Different Seams?
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...
What Is Modified Polyester and How It Removes Excess Weight
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...
How Fabric Blends Balance Softness, Stretch and Recovery
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...
