Comfortable and Tough

High quality tank! Let me tell you about this tank. First run in it I had speed intervals. It is an Oklahoma hot and humid summer. This thing fits well, is true size, and doesn't chafe. It is cool to run in even when it is gross out (was 98% humidity) and did not feel sticky. That is not the best part...the best part is this tank is tough. I tripped on a crack mid sprint and superman flew/slid down the sidewalk and into grass. Where many tanks would have torn there is barely a scuff. For as lightweight as this material is I was sure it was ruined and yet was pleased to see that there were no rips, the seams held up well, and after a wash the fabric had not frayed! Will be adding more to my collection for further clumsy runs.

Great tank. I will probably buy it in other colors too! It’s flattering but reasonably full coverage for a tank top. Did not chafe/rub at all for a 20+ mile, 5+ hour trail run on a brutally humid day, while wearing a hydration vest.

Feels good, running in heat warnings in NC over here. It's not the breeziest shirt possible but it's definitely breathing as hard as I am. I love the orange color.

great running tank top

Super lightweight, fit is very good. Wore this during a recent hot/humid/rainy 50k race and had absolutely zero chafing.

Extreme Heat

I wore this tank during an ultramarathon that was extremely hot and VERY humid. I kept myself pretty wet the whole time to help stay cool and this tank really has a cooling effect to it. It didn’t cling to my skin when wet. It felt cool to the touch all the time. Pretty sure I now need one in every color to wear all summer long. 😊 Great job Janji

I don’t know about all day…lol

I am loving my new tank from Janji! It does run small and I definitely don’t like them skin tight but the size I ordered fits well and is loose like I like them. Really soft material and it feels good on my skin!

Perfection

Just the right length, looseness and back coverage. Not a fan of racerback tanks because of the underarm/overbra bulge, and this tank covers that problem area nicely. Also very light for hot days and dries super fast. LOVE!

Perfect Tank

Love this tank! I thought about it for a while and it’s a perfect addition to my running closet. It works well as a base layer or single layer on warmer days. I’m generally a 36-38 C-D bra, XL-XXL for tops. The XXL fits perfectly.
