I have a jacket fetish. Not just cycling jackets but jackets of all kinds. I collect them it seems and, for the most part, wear them all. I have jackets for work. Jackets for recreation. And, jackets for cycling.
I do not apologize for this. I like to ride and prefer to be warm and dry. Having outer wear for all reasons, means I ride more frequently. And, I seldom pay full price. I look for deals. Even slightly used jackets find my closet.
When I put them all together like this (I have never done it previously), I notice they are white, black, red or a combination of these colours. They match my bikes. That is important. You want to look the part. Also, I notice of the six jackets are made by Louis Garneau (LG). They fit me best and I would rather be comfortable than fashionable.
Do I need 6 cycling jackets? Probably not. I also have arm wormers to keep me worm. Do I wear them all? Yes. Do I have a favourite? No. They are all favourites depending on the weather conditions.
Do you have a cycling jacket? More than one? If not, I suggest you purchase a jacket for each season. You will ride more often. I am not crazy about cycling in the rain but the cold and windy days are fun.

I do, just one. A Specialized Element. Otherwise, it’s arm warmers and long sleeve jerseys. That’s a nice collection you have there.
i have zero cycling jacket because i live in California and it rarely dips below 50 even in the winter, but i do wear compression sleeves mostly to cover my tattoos from the sun, and i have leg warmers for the colder sub 50 degree days, most of the time its bibs compression top or sleeves and a jersey, sorry to rub in my excellent riding weather
I was thinking about that. The reason I need different weight jackets is because of the variety of weather we experience in the Pacific Northwest. I envy you. I much prefer riding in sunny, warm conditions. I would save a lot on clothing if I were to move to a warmer climate.
