Why to wear a Thermo Cycling winter suit during Winter?

At G4, we are always looking for maximum comfort on the bike, to get a maximum of pleasure for everyone. After research and prototyping, we designed and developped the ultimate cyclist suit, the one piece integral just for you, which accompany you everywhere.

The real added value of such a product is wearing only one piece of clothes(accompanied in cold weather by a long-sleeved under-shirt). No more layers, that affect your comfort and freedom of movement, tending to reduce your performance. The goal was to create absolute comfort by bringing together all our innovations in one product. It’s the ideal outfit for any type of automn and winter climate. Our designer Geoffroy Lequatre has developed this product through his experience as a pro cyclist and his professional friends helped him too to get the best result approaching the perfection.


The combination of different fabrics is very important for us. We selected the best technical and fashinable materials. For the tights, the fabric is very stretchy, supple and warm. We added an anti-friction ceramic fabric insert around the seat to enhance the longevity of the fabric in contact with the saddle. The seams are invisible and flat above the knees. The ankles have a wide elastic combined with a reflective zip. All the bottom part has a water repellent treatment, to fight against rain and moisture. At the thighs, we inserted a warmer carbon fiber fabric in the front to protect against the wind and cold. The connection between the bottom and the top is made thanks to a very resistant seam. Finally, the G4 HD100 pad is the key to comfort thanks to this new concept of dual shape memory foam!

The upper part of the suit consists of a revolutionary membrane, fleece inside, windproof and water repellent on the outside. The cut has been reworked and lining in the lower belly has made its appearance, combined with a ventilated mesh, to ensure excellent support. The zipper of the upper body is made by a silver zip YKK, the german reference of the zips market. You can find an additional fabric under the zip to prevent the wind, which is passing through the zipper. Everything has been made thoughtfully in every detail to guarantee you an exceptional cycling clothes!

We added three large pockets including two reflective to be very visible on the road. The sleeves are well thought too, incorporating an aerodynamic, anatomical cut that provides great freedom of movement at the elbows and shoulders. The neck has a lined fabric, membrane on the outside, and very soft micro-perforating fabric inside, to maintain all the heat of your body. The total weight of this suit is 520g for size S. The design is very elegant thanks to the combination of different black fabrics, with a little graphic touch on the neck and on the pockets. The 4 metal dots are at the chest.

To accompany this exceptional product, remember to cover the extremities of your body as well. A good pair of winter gloves is therefore a priority, as well as a pair of Merino winter socks and a warm and comfortable Thermo winter shoe covers. This combination is effective between -2 and 12 ° C for road bike, cyclo cross bike or on your mountain bike. Very easy to put on, refer the size to your size of bibshorts. To maximize its maintenance, do not tumble in a dryer while you will disturb the effectity of the water repellent treatment. Program your washing machine on a short cold, sport program or 30 ° C maximum,  do not use softner.
