Santini Redux Stamina Women’s Gilet
This gilet is impressively warm for its pack size and weight, while also being breathable. It is expensive, but we'd say it is worth the money.
The Redux Stamina is made in Italy from Ghisallo stretch-woven fabric, and its checkered lining is Polartec Delta, which is very effective at keeping you warm on chilly starts. The collar is cut high and feels wonderfully cosy thanks to the thermal lining.
A light windproof fabric has also been added to the chest area, across the shoulders and the top of the back. It's well-placed to provide defence against brisk winds, while also supporting excellent breathability across the lower back and belly for an all-round comfortable riding experience.
The sizing is very well judged with no gaps at the arms to let air in and the slightly relaxed fit means that you can use it for both faster evening group rides as well as layering it in the winter.
Two slots have been cut into the back to allow you to access the pockets in your jersey so that you don't need to hoick the back of the gilet up to get at your snacks.
