Philippe, who is an accomplished sportsman and a triathlete, he did more than 15 Ironman and 20 marathons, : How do you choose your winter jacket?

“First, I like comfortable clothes! I immediately pay attention to the length of the sleeves, with a good coverage at the wrists so as not to feel the air coming in! You need a jacket that protects the chest well, as well, I  payed attention to the tight collar that avoid irritation, breathable  and the soft feeling is confortable.

Sweating is also the 2nd question, I do not like to sweat in a winter clothing, it must be ventilated otherwise I have cold immideatly!

The different Case when I had cold I know very well !!! In Bourges,(center of France) I need the real winter cycling jacket for winter traning and  the mid-season jacket I’m wearing almost every year! I spend a lot of time on my bike and most often on roads open windy and often rainy or even we have some snow! The thermo winter jacket must be well windproof and especially water-repellent if I ever have to go in the rain and also high visible in humid time.

Finally, I like having the “class” on my bike! And as Geo says, even if you’re not good on the bike, you must look beautiful! Followed advice, I will ride with the Denim jacket and the Distinguished cycling shorts this winter! I agreed and I adopted it directly.! “
