Honestly, I did take gamble on going down a size
In a tank …but omg!!! It fits like a handmade glove not to tight and not to big …just fitting…honestly how I’ve imagined a perfect fit I’ve only worn the orange tank and haven’t washed it ..I love it!! …and to top it off the material feels like this imported butter that I do not want to take off…I started trail running a little over a year ago and well you get it …it took over my life..I’ve entered a few 35K’s and I just finished my first 50K about a month ago…and my second 50K is coming up on April …I’ve lost like 17 lbs and I’ve never dreamed I’d fit into a M …thank you
and thank you for making my dreams come true
and helping me change into a person I’ve always wanted to be…with style!

Best Performance Clothing

Hey Janji Team,

I just wanted to say how much I love your gear—your materials are incredibly lightweight, breathable, and perfect for both my running and lifting sessions. As a dedicated hybrid athlete logging 60-80 miles a week and lifting 3-4 times weekly, I put my gear through a serious test, and Janji always performs.

I’d love the opportunity to represent even more of your brand in my training. If there’s any way to make that happen, I’d be beyond grateful!

Love the fit and the fabric

Really comfortable, no tags to bother you, great cut and fit for my relatively muscular 6 foot, 170 lb frame. Only Improvement I could suggest is to minimize/eliminate the graphic down the side of the shirt.

Typical Janji - great design and quality. This is my third Run All Day tank and won’t be my last (unless they sell out!).

The best!

The most comfortable tank I’ve worn running. Perfect fit: not too long, not too tight. Even in the hottest weather it doesn’t cling.

Best shirt ever

I bought this for my husband's birthday to wear bouldering. It is his new favorite tank top and says it is the best for hot humid days.
