Groovy Appalachian American MTB Shirt

My pal Hunter Davison showed up to ride Bernard MTN wearing the shirt. I had to have one. I'm a retired Green Beret and a topographical map pattern to me is like looking at a page in a book. All the boys thought that was funny when I told Hunter that. Now I've got the collared and t-shirt version. Thanks!
Put some of the Old Fort trail names on some shirts when you get around to it

love these shirts

I love these shirts, I have 4 of them now. I wear them mostly as casual shirts (I prefer to go sleeveless for MTB riding...it's too hot in Florida!). I even got married wearing one

That is EPIC Matt!! Congratulations and thanks for taking the Catalyst Shirt to a new level :)

just perfect fashioned product

I like the smooth and free feeling in there. Im 186cm tall with 90kg. I order xl but it can be just L as well good.

Almost Perfect

This is a minor thing, but I'd like to have larger armholes for a more relaxed arm fit. My arms are about 17" around and the sleeves felt tight and a little restrictive.

Love the color and pattern

I actually bought this because of the color (love green!) This one is a little more loose than the women’s model but still great for a relaxed shirt on the commute or gravel ride. Great quality on the stretchy fabric. Adore it. Bring more colors/patterns for the ladies version!

Great jersey!

Bigger guy, sweats a lot. Have used all variety of jerseys over 25 years mtn biking. For me, the Catalyst is great for breathability, comfort, fit, usability (love those snaps) and so far durability. I've mudded it up a couple times and sumple machine wash has been fine for getting right back to like new. Very happy, will buy again.

I love the fit and the stretch of the shirt. It's super light and perfect for hot summer days.

Great Design and Great Fit

I was hesitant before buying this shirt due to its price but the topo map look and the color got me interested enough to bite the bullet. So glad I did. This is my new favorite shirt. It is light and strechy and so comfortable. I received so many compliments about it. If you're hesitant too, you should go for it!

Fantastic shirts

Let's get this out of the way - I don't ride mountain bikes. I trail run, hike, and lift. I came across these shirts during Tuck Fest at the Whitewater Center in Charlotte. They are hands down the best, most comfortable button-down shirt I've ever warn. The slight stretch, the proper fit on the arms and shoulders... I could not be happier with my purchase. I now own 3 of these shirts and would buy more if the color scheme was expanded. I'll be hiking the Dolomites in September and all three are coming with me. With the silver built into the shirts, you have the ability to wear these for 2-3 days without an issue, making these a HUGE travel win! (Yes, I've tested this). Great shirt, well worth the money.

Not bad, not great.

As my title says, the jersey isn’t bad, it just leaves something to be desired. Compared to a few of my other jerseys at similar price, it feels cheap and heavy. The jersey looks great but I honestly expected better quality. Plastic snap buttons are unacceptable and the material seems to hold much more sweat than a quality jersey. I live and ride in Colorado, and was hoping these would be good summertime jerseys but unfortunately I’ll have to keep them around for spring/fall. Based on the sizing chart, I measured my favorite fox jersey to compare. I would say the fit is true to size just a bit short in length from head to waist. Overall these jerseys look great and function on a mediocre level. Two stars because I don’t see them getting more comfortable with use.

Hi Dieter, thanks for the thoughtful review. On the snaps: we went with a low-profile plastic snap by design, for weight and durability, and it's rare feedback for us as you can see from the other customer reviews. On the fabric performance, this is also very rare feedback for us on the Ion Pro material as we've done extensive testing in numerous conditions and it's definitely become a customer favorite. At the end of the day we're sorry to hear you were not happy with it.

Quality shirt, great design

My husband loved this shirt for Father’s Day! He’s worn it biking several times, and also to work. Very versatile and well-made.

Best shirt ever!

These are by far the best button downs ever! Cargo bibs and a button day is my go to and these blow my others out of the park. Can’t wait to get more.

The best shirt

This is the best shirt hands down. I have 2 and just ordered a third. Comfortable, breathable, quick drying, well made.

Great so far

Loved the first one I got so I got two more. When I was looking through, I hope they. Ring back some old designs or refresh what they have now.

Paul (Richland Center, WI)
great shirt.

Love these shirts. Perfect fit for on and off the bike. My only suggestion is to put a snap on the pocket so it stays closed, and perhaps a stiffer collar so it doesn't flop down as much.

Great shirt for both casual and riding

Best shirts for work n play

I wear these everyday to work and they are so breathable, great for travel and mowing grass or a quick mtb lap. Hidden pocket works great for layer or passport. Some more muted designs/colors would be only thing I’d change!

Cool and tough, yet stylish and refined

Worn this a few times and it's great on the bike and for looking good during Apres. Snagged the shirt on some branches during trail rides and it didn't tear.

Plastic snaps are unimpressive

Love the design, not particularly enamored with the plastic snaps

Hi James,

Thank you for taking the time to leave a review the Catalyst Mountain Bike Button-Down Shirt. We're glad to hear that you love the design! We wanted to address your concern about the plastic snaps. We have been using these snaps for over 3 years now and with over 100,000 snaps in circulation, we have only had a handful of failures... probably less than 10! And if by chance you have the bad odds of having one break we will repair it for you free for the life of the shirt! Thank you again for your support and we hope you continue to enjoy our products.

Excellent service, excellent shirt

Ordered a shirt on close out and received a text from the guy in the warehouse apologizing that they didn’t have my size. Offered to replace with new pattern at no charge. Great service. Easily the best MTB shirt I own. Won’t hesitate to buy another at full price. You shouldn’t either.

Form fitting, light and stretchy. Very comfortable! Also, I ordered 2, but accidentally placed 2 separate orders, so there was an extra shipping charge. Cognative combined the orders, and refunded the extra shipping charge. I didn’t even have to ask! Great company and service!

Dual use

I saw this shirt at a non-race, local MTB event. I loved the look and material. First ride, great for a relaxed ride around on the town trails. This week I wore it to work because I knew that would “make” me get on my bike after. To my surprise, at least 5 complements on the pattern, material, and fit. Great product.

Solid shirt, wicks well,

Like the look, fits me well, (Large, 6'1", 200lbs). worn it for a few work outs so far, happy with the comfort on the bike and its wicking. Wife commented I probably shouldn't wear it without a undershirt, so a bit more transparent than some other styles.
