Cycling Weekly Verdict

Velocio has come up with another well-constructed piece of kit to rival the likes of Assos and Castelli; performance and comfort are first rate. Its sustainable approach adds extra appeal to those wanting to invest in premium kit. The CONCEPT Radiator Jersey is best suited to hot weather and the cut will appeal to those hoping to make performance gains. With only a couple of reservations to note, some might consider it worth the outlay (£154/$199 at the time of writing).

Testing and reviewing jerseys is certainly not as straightforward as it used to be; gone are the days when, at the start of each season, brands offered one or two new jerseys, possibly in a few different colours. Manufacturers now go out of their way to cater for several disciplines, varying levels of experience and ability, a wide range of tastes and any kind of weather condition that Mother Nature can throw at us.

Have a look at our guide to the best women's cycling jerseys and you'll see what I mean.

It’s easy to get overwhelmed with descriptions and titles, particularly when there are several different jerseys from one manufacturer all with similar names. Velocio’s CONCEPT Radiator is a good example of this. Back in 2020, we reviewed the Velocio Radiator Mesh Jersey, designed for very warm conditions. This is still available on its website, so clearly a big hit. 

Then the Velocio CONCEPT Jersey arrived, with an aero cut and performance fabrics..

Fast forward to 2022 and Velocio has combined the traits of both jerseys to make its latest, most advanced, high performing jersey, the CONCEPT Radiator Jersey. I was keen to see what the fuss was about - both the Radiator Mesh and the CONCEPT got rave reviews with Colin stretching to 4.5/5.


The front torso and sleeve panels mimic the Radiator Mesh Jersey; they use the same textured, perforated Polartec Delta Mesh material. The tencel and recycled polyester yarns create a 3D mesh structure intended to wick and absorb moisture, then actively cool through evaporation as you ride. Unfortunately, Polartec Delta Mesh doesn’t boast UPF - not ideal for the upper arms.

The rear panel thankfully offers UPF 30+ protection. The fabric's open-knit structure is design to offer a degree of compression as well as breathability. It’s made by Italian brand M.I.T.I whose reputation for sustainability falls in line with Velocio’s.

A low-profile neckline, mimicking both the CONCEPT and the Radiator Mesh, is designed to reduce bulk and maximise airflow. Beyond that, the CONCEPT Radiator takes the same fit and patterning as the CONCEPT; it’s focused on aerodynamics - expect a close, streamlined fit with no wrinkles or bagging. 

Even with traditionally stitched hems in several places (rather than raw-cut), the jersey still only tips the scales at 125g (MEDIUM).

A lightweight YKK CamLock zipper is kept away from the skin with a soft, supple full-length zipper guard. This extends at both ends to create garages that protect the neck and shorts.

The well judged dropped rear is supported with a band of silicone-lined elastic. At the front edge, the hem is bonded for a smooth transition to shorts.

Four pockets, including a zipped one, have an elasticated top hem to help keep contents secure. It's lined with silicone on the underside, presumably to prevent anything ‘slipping’ out. The zipped pocket has a moisture resistant lining. 

A decent sized, well-placed reflective logo finishes off the pockets, helping to increase visibility in low-light conditions.
