Santini Redux Short Sleeve Jersey



A very good hot weather jersey with cooling and UV protection, though the price is hard to swallow

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 Redux Short Sleeve Jersey performs well as the mercury begins to climb with excellent cooling and a figure-hugging aero fit, but this comes at a price.

  • Pros: Great in hot weather, UV protective
  • Cons: Expensive

When I was sent this jersey I looked outside at the 6 degrees day and the rain that I'd ridden to work in and thought that this was going to be a difficult review. However, three days later I found myself out in the Kent hills in 28 degrees – which was prime reviewing conditions for this jersey.

Santini has sold this jersey almost exclusively on its ability to keep you cool in hot conditions, with the Italian company giving it a 5/5 for breathability and anti-UV protection. You only need to look at the famous picture of Chris Froome after he'd tested out the latest Team Sky mesh speed suit in 2014 to realise that one without the other is a recipe for disaster.

Breathability on the jersey live up to the marketing: it's exceptionally good and I found that even when I was midway through a regular long slog of a climb I was surprisingly cool, with sweat being wicked away quickly keeping the jersey dry to make sure that this cooling effect was maintained. Santini recommends this jersey for rides between 18 and 35°C and I'd concur: I tried it at around 13°C and it certainly would have been nicer to have a little more insulation.


It is also UV protective, which is proven by the tan lines on my arms; because this is an aero jersey the sleeves are elongated, and when wearing a brown T-shirt the day after my ride I realised I looked like a tub of Neapolitan ice-cream. This is impressive because the material is so thin, with breathability being such a key design feature, but Santini has still managed to incorporate UPF 50 protection.


Helping with breathability is the full zip, so if you do end up getting too hot despite its breathability you can just unzip and let in more air.

Santini markets the Redux as an aero jersey, with the fabrics wind tunnel tested, and there are some strong design features to reflect that such as the collar-less element, which also stops irritation around the neck, the silicone grippers at the bottom of the jersey which stop it riding up, and three laser cut pockets at the back.


Santini must have recognised that the material used throughout most of the jersey would probably be a little too thin for the pockets, so a thicker fabric is used here, with slits cut close to the top for access. Although not the largest, the pockets are big enough for everything I need on a hot ride, and to be honest the kind of rides you'll do in this jersey probably aren't those where you'll need to store larger things like jackets or even arm warmers.


As the fit on the jersey is designed to be as aero as possible, it is form fitting with an impressive amount of elasticity in the material meaning that, although tight, it isn't restrictive. Sizing is as you would expect from an Italian brand, with the large I tested being similar to a medium in UK or US brands.


One thing that does count against the jersey is that the high breathability and well-thought-out design come at a cost: an RRP of £135. Okay, it's £5 less than the Rapha Pro Team Aero Jersey, but it's £35 more than the Castelli Aero Race 5.1. However, if you are in the market for a lightweight, hot weather, aero jersey, this is certainly up there with the best.

Overall I was really impressed with the Redux Jersey; it has very impressive breathability, kept me really cool, and has some very well-thought-out design features. Price is definitely going to be an issue for many, as a short sleeve jersey for over £100 is steep, but performance-wise, if you are in the market for a high-end hot-weather aero top you won't be disappointed.

Tell us what the product is for

A lightweight jersey designed for the hottest rides.

Santini says:

Fit - Lightweight, extremely aerodynamic and UV resistant (UPF 50+). Thermowelding instead of stitching creates perfect airtight seams that streamline the airflow around your body. Joint cut shoulder construction for maximum range of motion.

Performance - The secret to the Redux is it's Prey fabric construction with Flow fabric inserts which are stretchable yet maintain compression in order to reduce the wrinkles and minimize 'flapping' even at high speeds. The structure of these fabrics is very compact with a large amount of very thin threads, in order to minimize the passage of the air flow trough the fibres between the fabric and the skin. Instead of external pockets, it features a triple inner pouch with an almost invisible thermos-sealed laser cut opening.

Comfort - Redux materials will keep you cool while you ride through the hottest heat waves. The Flow fabric doesn't just let your body breathe, but actually channels heat away from the body for more efficient cooling.

Durability - All fabrics are sourced and assembled in Italy. 100% handmade guaranteeing long-lasting quality even after hundreds of rides. Each garment undergoes vigorous quality controls and will last a lifetime.
