Riding in winter with Q36.5: our experience with the Interval Termica jacket

Winter has arrived, and with it, that familiar dilemma for us passionate cyclists: continue riding outdoors or take refuge on the indoor trainer. But in recent years, the situation has changed. With advancements from major manufacturers, it is now possible to ride in extreme temperatures while remaining comfortable. In this series dedicated to winter gear, I’ve chosen to start with Q36.5, an Italian brand that continues to gain momentum.

Q36.5: A brand designed for extreme cold

It’s no coincidence that this brand, based in Bolzano, at the foot of the Dolomites, has become a must-have for winter cycling enthusiasts. Under the impetus of Luigi Bergamo, its founder, Q36.5 has made it its mission to design gear that allows riding in all seasons. With Vincenzo Nibali as ambassador and technical advisor, their expertise is reflected in every product.

I had the opportunity to test their Interval Termica jacket, a piece I use daily this winter. Let me say it upfront: this jacket has everything to become the cornerstone of your winter outfit.

Insulation and breathability: a perfect balance

The first thing that struck me about the Interval Termica is its balance. Made with 11 strategically placed fabrics, it achieves the feat of retaining warmth without ever becoming stifling. During my rides in the Alps, where temperatures dropped to -3°C at the start and up to -8°C during the ride, this jacket proved impeccable. It may be hard to believe, but I never feel cold with this jacket. And for a set of reasons.

The double layer is reminiscent of some well-known models, such as Castelli’s Alpha RoS. Here, the jacket only requires a technical base layer to function fully. I used the brand’s Base Layer 3, and this combination proved ideal. I also used other base layers from competing brands. I sometimes felt more covered, less light, as if the symbiosis was not as good. Here, at no point did I feel the need to add or remove a layer, even on climbs, when effort raises body temperature.

Weather protection

Although this jacket is not designed to replace a rain jacket, it resists light rain and spray very well. During a ride in almost constant drizzle, my upper body stayed dry. The waterproof and practical CamLock zipper plays a big part in this, as does the snug fit that limits cold air infiltration.

A jacket designed for all phases of effort

What I particularly appreciate is its versatility. On climbs, sweat wicks away without a problem, even when I push at a steady tempo. And on descents, I never had that unpleasant sensation of icy cold caused by residual moisture. One of the strengths of this jacket is the ability to open only the outer layer for ventilation without directly exposing the body. This allowed me to effectively manage my temperature, especially in changing conditions.

It is nevertheless not as aerodynamic as some more form-fitting jackets, but at least you can ride. Comfort is also an important factor in performance.

My assessment after several weeks of testing

Over the course of my rides, the Interval Termica has become my go-to jacket for winter. It perfectly manages temperature variations, protects against light bad weather, and fits like a second skin.

Of course, it integrates perfectly with other products in the Q36.5 range:

• The Base Layer 3, which is a honeycomb-shaped base layer that perfectly regulates temperature between +10°C and +18°C. Yes, you read that right, I deliberately didn’t opt for a warmer base layer like the Base Layer 4, which works between -5°C and +10°C, or the 5 with a hood, because I naturally generate a lot of heat.

• The Hiver Super Termico gloves will provide good protection down to 0°C, but we will see later for these temperatures, our comparison of heated gloves can be useful if you often ride in the cold or suffer from Raynaud’s syndrome.

• The Termico Overshoes are in line with the products presented here and complete the range, as do the Woolf Leg warmers which pair perfectly with Wolf bib shorts. The latter are warm and fleece-lined bib shorts intended more for mid-season when you can remove leg warmers, otherwise Dottore Termico tights remain a safe bet…

Why I recommend the Interval Termica

If you are looking for a jacket that allows you to ride in temperatures from -5°C to 10°C without compromising on comfort or performance, the Interval Termica is for you. As a demanding cyclist, I know how difficult it is to find equipment that combines protection, breathability, and lightness. With this jacket, Q36.5 has clearly met this challenge. So, ready to face winter? For my part, with the Interval Termica, I have never been so motivated to ride, even in very cold weather.

It should be noted that it only has two competitors in my eyes: the Alpha RoS 2 from Castelli and the Q36.5 Termico Dottore, which is simply the new name given to the jacket!

The question of price remains: at nearly €450, it represents a significant investment. However, being able to train is a priority, much more than a simple training camp. It’s a long-term investment, with materials and quality designed to last. My 2023 jacket, for example, has only been modified by its name and shows very little wear despite daily use in recent seasons. In short, if fresh but cold air attracts you more than Zwift, this jacket is an essential part of your wardrobe!
