Thermal Jacket Defend

Suarez Thermal Jacket Defend

The Suarez Thermal Jacket Defend is a high-performance winter cycling jacket for rides in temperatures ranging from −2 to +8 °C – ideal for long training sessions in the cold or daily commutes in Switzerland. The front features a three-layer construction with integrated membrane to effectively shield against cold shocks and headwinds, while the back panel deliberately remains breathable. Inside, the brushed X‑Fleece provides noticeable warmth and pleasant thermoregulation, so you don't overheat when your heart rate rises. Additional features include white reflective details, a full-length YKK zipper with internal wind protection, and a practical rear pocket for valuables.

Technical Details and Features

The Defend combines two material zones: three layers including membrane at the front against wind and cold, and a targeted breathable textile at the back for moisture transport. The internal X‑Fleece is soft to the touch and supports balanced heat regulation, keeping you warm without overheating. The full-length YKK zipper sits on a flexible, ergonomic tape; an internal protector prevents cold air from entering. Side panels increase freedom of movement, while the new front hem with silicone gripper reliably keeps the jacket in position. The high-stretch construction adapts to your riding position and ensures long-lasting comfort.

Applications and Benefits

Whether road cycling, gravel riding, or commuting: this thermal jacket shows its strengths when temperatures drop and the Bise wind blows. On long base training rides, the front reliably protects against cooling, while the breathable back allows sweat to escape. During short winter days, the white reflectors increase your visibility on country roads and in the city. The fit remains close to the body even with a baselayer, maintaining aerodynamics and minimising flapping. Thanks to thermoregulation, the jacket is suitable for both steady base kilometres and more intensive intervals on flat terrain.

Fit, Sizes and Variants

The Suarez Thermal Jacket Defend is available in five sizes from S to 2XL and was designed for an ergonomic fit on the bike. Through the side inserts and elastic material, it hugs the body without restricting freedom of movement. For complete winter gear, the jacket combines ideally with thermal bib tights and winter accessories to extend the usable temperature range in cold conditions. The Defend is also available as a women's variant with identical temperature focus in the Thermal collection. This way you'll quickly find the right option for training and everyday use in Swiss winter.

Material and Layering Tips

For most rides between 0 and 8 °C, a functional baselayer under the jacket works excellently; in significantly sub-zero temperatures, a slightly warmer baselayer is recommended. Plan to open the YKK zipper on long climbs and close it early before descents to prevent headwind from penetrating the layers. Combine the jacket with windproof overshoes, thermal tights and warm gloves to unlock the full potential in cold conditions. Wash the jacket gently and don't use fabric softener to preserve the membrane properties and X‑Fleece long-term. For visibility in low light, reflective accessories like caps or arm warmers pair particularly well.
