Fast dry for a sweaty lady

Disclaimer: I work for Janji. Another disclaimer: I'm a sweaty gal.

That means I've tried *a lot* of Janji gear of the years, specifically in a quest to manage sweat. I can confidently say that this is the lightest, fastest drying material we've made. I wore it this morning on my run in Brooklyn and it was dry by the time I finished. How does that even make sense?

I am usually a medium and ordered a medium. It's a nice, relaxed fit - not too snug, not too baggy. Definitely going to be my go-to for sticky, summer runs.

Perfect tank

Ultra light, comfy fit (loose but not baggy), and fun colors. This is my go to tank of the summer!

It’s ok

The seam is a little odd on me since I have a small chest.

Weird fit

I purchased this tank because I loved the print and I live in a location where you can wear a tank top most of the year. However this one fit weird: the bust was way too large. I am a runner who carries my weight in my midsection so going a size down would have been snug around the waist and questionable on if the bust would fit (that's how large it ran) so I returned. However the material is really nice, and Janji items always perform well, so I feel comfortable still giving it three stars. For reference I am 5'4", last I checked 160 pounds, and usually wear a medium but occasionally a large. I ordered and returned a large.

If only...

It hurts me to leave a less than stellar review on anything Janji, but here we are. Janji women tops are not made for pear shaped women. I ordered a small and a medium in the Helio tank, and I was SO excited. It was everything I wanted in a shirt. Why are there so few high neck running tanks for women?! The fit just doesn't work for me though. The top of the small fit perfectly, but the mid section was WAY too tight for someone with hips. The medium had MAJOR gapping in the top, and the mid section fit but was still tighter than I would have preferred. I had the same issue with the singlet!

The fabrics and design are exactly what I want, but some of us don't have enough of a chest and too much hip to fit into Janji tops. Heartbreaking.
