Frequently Asked Questions

  • I'm a skinny guy and not as muscular as the models, will these Jeans still fit me?

These Jeans give a fitted look, even on slim-legged guys, ensuring the hip, bottom and ankle area do not get excessively large and baggy.

  • I have thick thighs and jeans never seem to fit me, will these actually fit?

The ultra-stretch allows expansion up to 10cm/4inches in the thigh area so they stretch & shape to your size. Our experience is bodybuilders or guys with especially thick thighs may find it more comfortable sizing up one from their measured waist size or check out our Slim Fit Jeans which have been tailored specifically for this body type.

  • I’m not really athletic and a bit more dad-bod than bodybuilder, will these fit?

Yes, these have a flexible waist and will also allow for ”Seasonal" weight fluctuations.

  • Who don't these Jeans suit? 

Although they have a feel more relaxed than it looks, if you don’t want a skinny fit look, then we suggest our Active Tapered Slim Fit Jeans

  • I have had bad experiences with online shopping and I have never heard of Kojo Fit?

We have sold thousands of athletic fit clothing products to guys across the world. We only accept verified reviews from purchases. We truly care about giving the perfect fit, if you are not satisfied, we encourage size exchanges and returns. With 100% Fit, Comfort & Quality Guarantee, never get stuck with a bad fit!
