At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

The Santini Grido Thermal Unisex Long Sleeve Base Layer is excellent for winter riding. The fit is brilliant, and the dual layered fabric offers bags of protection from the cold, but it comes at a hefty price.

The prospect of rain, sleet and snow puts many people off cycling in winter, but with the correct kit it can be great fun. A good winter baselayer will help to insulate your body by trapping the heat you produce through physical exertion, and wick away sweat to prevent freezing at the cafe.

Now there are many baselayers out there on the market and plenty of choice, but over the testing period I have come to love the Santini Grido. It's the most effective thermal baselayer I have ever tried. Santini has made a perfect cycling thermal for both on and off-road riding.

Starting off with the material composition, the Grido Thermal has a merino wool interior with a more stretchy form-fitting polyamide exterior. Merino wool provides plenty of warmth along with moisture-wicking properties – exactly what you want from a thermal – while the polyamide exterior gives the baselayer a close comfortable fit around your torso.

There is no loose fabric around the neck or the arms, and this combination of fabric choice and cut means the baselayer fits perfectly under a long-sleeve jersey.

The length is perfect, too, with the shaping at the hem allowing for a smooth integration with bib tights, preventing any additional irritation and minimising the chance for any cold air to reach your skin. I'd say the baselayer comes up true to size: for reference I am 6ft 2in and 75kg, and a size medium fits me perfectly.

As for the operational temperature range, I found the Grido comfortable from 8°C and below for both off-road riding and cycling on the road. It is possible to remain comfortable on the road at warmer temperatures thanks to the increased air flow, but off-road I would opt for a lighter baselayer.

The only real downside to the Grido is the price. It's the best thermal baselayer I've used, but at £120 it is also the most expensive! The Assos Ultraz Winter LS Skin Layer comes close at £105 (Emma tested the women's, the men's is the same price), and GripGrab's Freedom is £90, but Matt thought the Spatz BASEZ 2 Black Baselayer was superb for cold weather (if lacking adjustability at the neck) and that's 'only' £75.

Overall, the Santini Grido Thermal is a fantastic winter baselayer, but there are plenty of very effective thermals for less.

Would've snatched Santini's hands off last week, but it's going to be 13'C tomorrow and 17'C over the weekend! YAY! 😁
