Caring for your cycling gear properly will extend its life and maintain its performance, fit and quality. Its important to consider these instructions carefully. While we stand behind the quality of our apparel, not adhering to these instructions will void our warranty against manufacturing & defects. 

We strongly recommend washing your new gear before wearing it. Youll find that your apparel will soften, and fit & comfort will improve after washing - especially with bibs & shorts. 

Machine wash cool, 86F (30C) with like colors: Cooler temps maintain better longevity for your apparel. Like colors, especially lights, will remain more vibrant when washed with like colors. 

Use mild detergent. Do not bleach or dry clean: Strong detergents & bleach can break down the fibers and elastane in the garment, dramatically reducing its life. 

Close all fastenings: this goes also for other garments mixed in with your cycling apparel. Velcro closures or clasps can catch on stitching or trim and damage your garments. 

Lay flat to dry. Do not tumble dry: Do not put your cycling apparel in the dryer. Even on low heat. Dont do it. Heat can damage fabric, elastic and heat transfer logos very easily. Lycra (Elastane) is used throughout our garments to provide compression and support and is susceptible to damage from heat and can irreparably damage your apparel.


How do your jackets fit?
Our jackets are patterned in the riding position, with a tight fit across the chest and arms with a more forward position. This is intentional to reduce flapping and extra fabric across the chest while riding. When standing, the jacket will feel tight across the chest, shoulders and torso. The arm length might appear long as well. However, the intended fit is tailored for on-the-bike positioning where the shoulders and torso no longer feel tight and the extra arm length hits the wrists in the appropriate spot. Constructed without extra fabric to flap around - it should fit tight over your jersey (with enough room for a long sleeve and base layer), but shouldn’t appear baggy. We select fabrics that have some elasticity to allow for freedom of movement even with a tailored fit to accommodate some range of fit within each size.

Great cold weather jacket

Keeps you very warm and you can vary how warm it is with your base layer. I have used it on gravel rides down to low 30’s with a light wool jersey under it and done well. It blocks wind well and dumps heat on climbs with just a pull of the zipper. It is slightly short in the torso for me at 6’2” and having a long torso but on the bike it fits perfect. Good coverage in the back for tire spray as well. Overall I love this jacket. .it would be great if there was. Tougher version for mountain biking with a looser fit.

Absolutely perfect

This is my favorite piece of kit. I only wish I got it at the beginning of winter. I use it in a wide range of temperatures and only need a base layer. It is pricey but well worth the investment.

For those in the northern hemisphere

Great jacket. Being in central WI, ones cold weather gear needs to be very flexible, and this jacket is super warm when layered but also usable in higher temps ~45 with less layers. Super windproof. I am 6' and around 180 lbs and a Medium fit great.

Awesome cool to cold weather jacket

This jacket is very versatile. It deal with wind and moisture very well and can be made warmer or cooler depending on base layer. It dumps heat well on climbs with a quick unzip and warms back up quickly on the descent. It is worth noting that unzipping before you get hot is a good idea. It will dry but is better if you just don’t get it soaked in the first place.

Unbelievably warm

I have ridden with this a few times now. It is crazy how comfortable and warm it is. The best part about it is that I forget it is even there. Beware that this is a snug fit, I had to size up to get it to fit where I felt comfortable. Fantastic piece of gear.
