All size guides on the Prendas website have been specifically prepared to help you get the right size garment. We do not use generic charts from manufacturers, we measure every garment that we sell.

For this garment, "Harry" the mannequin (which the vast majority of our product photographs are taken on) wears a size Large and he measures chest 39"/ 99cm, height 6`0"/ 183cm. It is worth noting that our sizing recommendations are based on a close fit, so if you want a bit of room, it is sometimes advisable to go up one size.

A breathable, lightweight, windproof and packable gilet is an essential item in any cyclist's drawer to combat changeable and cooler conditions.

In simple terms, a gilet (pronounced gee-lay) is a sleeveless, lightweight jacket, usually made from a windproof fabric. If changeable conditions look like they will affect your ride, a gilet (in addition to a pair of arm warmers and knee warmers) can offer some great protection from the elements, and if it happens to warm up, can be easily stored in a rear jersey pocket.

The fabric used on this product is in itself very interesting.  Made in Italy, this gilet uses two fabric layer bonded together for the best possible performance.  The black outer layer being composed of a polyester that's had a water repellent treatment and the inner, called ZeroWind, which is a hydrophilic membrane that has excellent thermo-regulating properties and as well as breathability.
