Cold-weather running has a specific problem. It is not just getting warm. It is staying regulated once the effort changes.

Start cold, warm up fast, sweat into the wrong layer, then chill when the pace drops or the wind hits. That cycle is exactly what the GridFleece Pullover was built around. It takes the work we have done with GridFleece in our cycling thermal jerseys and rebuilds it for a different posture, a different movement pattern, and a different kind of winter effort.

This is not a cycling jersey with running tags added to it. The silhouette was recreated for running: formed through the body, shorter through the front, and shaped with a little more length at the back without turning into a long cycling cut. The goal was simple: keep the garment close enough to regulate, but natural enough to move.

Built From GridFleece

At the centre is GridFleece, a 260 GSM thermal fabric already proven in our cold-weather cycling range. The grid structure gives the fabric its usefulness: warmth through loft and structure, but with channels that help moisture and air move when the body starts producing heat.

That matters because winter training rarely sits at one intensity. The first ten minutes are different to the climb, the interval, the coffee stop, or the run home. A good thermal piece cannot only trap heat. It has to manage the moments when the athlete creates too much of it.

The Running Silhouette

The biggest change was the shape. Running does not need the same length, pocket structure, or riding-position geometry as cycling. The GridFleece Pullover is built with a firmer active fit and a cleaner body line, designed to sit close without excess fabric moving around.

• Formed through the body: close enough to make the thermal fabric effective, without building bulk into the layer.
• Shorter front length: adjusted away from cycling proportions so the garment feels natural when running upright.
• Slight rear coverage: a little more length at the back, but restrained, so it protects without feeling like a riding jersey.

Quarter Zip, Real Range

The quarter zip is not just a styling decision. It gives the garment range. Fully zipped, it works in the depth of winter with a buff, neck tube, or face covering. Opened up, it vents quickly for milder conditions — the kind of winter you get in places like Brisbane or Sydney, where you still need warmth early, but not a locked-down thermal shell for the whole session.

That adjustability is the point. The pullover is built for cold starts, changing effort, and changing weather, not one perfect set of conditions.

The Detail You Notice Late

The thumb hole is a small detail, but it changes how the piece works in real cold. It keeps the sleeve settled when layering gloves over the top, and gives enough hand coverage when gloves are not needed. For Northern Hemisphere conditions, that matters. For Australian winter mornings, it gives the piece more use without forcing extra accessories.

Small on paper. Obvious in use.

Testing and Use

The GridFleece Pullover has been in testing for a while, and the early response has been strong. The feedback points to the same thing the product was designed around: warmth that does not feel static, a fit that belongs to running, and enough adjustability to handle different winter conditions.

“It feels warm when you first step out, but it does not get heavy once you start working. The quarter zip and thumb holes make it easy to adjust through a run, which is exactly what you want in winter conditions.”

What It Is For

The GridFleece Pullover sits in the 360 range as a winter running thermal. It's for temperatures of around 0–15°C, a firm fit, thermoregulation, and moisture management. That combination is the story: a piece built for cold-weather training where the athlete is still working hard enough to sweat.

It is warm, but warmth alone is not the point. The point is regulation.
