Super tough on the nips. This tank makes me chafe so hard, unlike any other fabrics.

The Ultimate Tank for Chafe-Free, All-Day Miles!

This tank absolutely lives up to its name. The fabric is incredibly lightweight, breathable, and does an amazing job of wicking sweat even on hot, humid long runs. What I love most is the fit—it is completely spot-on and doesn't cling or cause any chafing under the arms. It feels like you're wearing almost nothing at all. Whether you're training for an ultra or just heading out for a daily loop, this is hands-down the best running tank I've owned!

Perfect running shirts

These are my favorite running shirts ever. No chafing and looks good. Only complaint is the shipping is pretty slow.

Definition of unobstructive

For those days you don't wanna wear a vest, feel the breeze through ur pits, and listen to Distance to Empty 🤙 It's like you're not wearing a tank at all.

Looks great, shreds nips

I run 30 miles a week in a variety of shirts - Peloton tanks, LuLu tees, Adidas, whatever. I’ve never had a nipple chafing problem. First 3mi run with this tank and my nips were on fire in the shower. My 2nd run in the top was a 7 miler and my poor nips bled through the tank.

It’s a good looking piece of kit and I guess the blood stains look tough maybe but not what I expected for $60.

I love this fit - no flapping or sticking when I run - and light enough to feel like it’s not there.

Once again, fabulous

My go to option for every run is a Janji top. Light, cool, and I would guess they are comfortable but it's difficult to discern because I'm not sure its there when I have it on; I like them that much. Great top, great company, superb craftsmanship. Would, and will, buy again.

New Favorite Tank

The material is so breathable and lightweight. It just fits very well also even for a bigger person. Bought one to try out and I’m getting more for sure
