I like these pants a lot.

Because I already had another pair of perfectly functional riding pants, I was poised to send these back; but decided to slip them on for comparison. They stayed on; and I haven't used the other pants since. I like these pants a lot. They fit just right (34 and true to size), are well designed, and are of good quality. They are also not too bulky; and I expect I can use them for 3 seasons.

These are the pants you want

Just bought my second pair of fat jacks after shrinking out of my previous pair. The fit and finish is great, and their magically cut so they don’t get snagged on stuff despite feeling roomy. Phones and keys go great in the zip pockets and seem to disappear when you’re riding, Perfect weight for 15F-40F winter rides. Add a belt to keep em up and enjoy!

FAT JACK PANTS - Great Value!

Very happy with the quality, build, and features of these pants. They are easily on par with similar pants that cost nearly double. Since I started life as a roadie, I have a fairly thin waist with larger legs. I'm 5'11" with a 32.5 inseam and weigh about 168. I ordered the 34 assuming that would give me some room to wear bib shorts or an under layer on cold days. The length is perfect. They are just snug enough. The waist is a little loose but I that's very typical for me with all pants. I run them with suspenders and all is good. The 32 would be to snug.

Great pants and great customer service!

I personally have these pants and I love them. Great winter fat biking pants, snowshoeing pants, and I also use them often for hiking and other fall activities. I also ordered some as a gift and had some troubles with sizing and a defect in one of the pairs and the Club Ride Customer Service was so good and easy to work with. I can't say enough good things!
