Built for You
We believe in the freedom and positive benefits of cycling. Whether you are a beginner mountain biker, weekend warrior, Enduro racer, or just love riding bikes with friends, we built our MTB gear for you.
Got this shirt for my husband, and he loves it. One note - the size chart recommended sizing up to get a regular, not fitted fit. This was not necessary at all. So when I emailed the Cognitive MTB team to ask how to initiate and exchange, I got a very quick reply with a link to get started. They shipped the replacement out ASAP, and I could not have been more pleased.
I am really happy with the quality of your products. Ordered a t-shirt, a gaiter, and some stickers, they are simply great! Thanks a lot, bros, stay safe and keep sending it!
Used the sizing chart to pick the suitable size for my husband & it fits perfectly! Material is very soft & comfortable
I’ll buy any 3x shirt Seth puts out.
Great shirt. This is probably my fifth one. Super soft and true to size the fit is great. When I need more shirts I will be back
