sustainability

Runterra is made from premium, long-staple Supima® cotton which is 50% longer and up to 45% stronger than other cottons (and softer too). The stronger the fiber, the more durable the garment, and therefore the more it can be worn. Supima® cotton is grown by a select few family farms that utilize advanced water and soil management techniques to reduce consumption and ensure the health of the land for optimal renewability.

 

Runterra fabric is also OEKO-TEX® certified meaning it is free from harmful chemicals and is fabricated in a way that meets a high environmental standard.

So Lightweight!

This is my current favorite running top! I hit my highest distance in this and felt cool the entire time. This moisture-wicking is pretty impressive and it dries quickly. I love the idea of infused volcanic ash, so I don’t have to worry about smells. One less thing to worry about.
I would suggest ordering a size up from your normal if you have a larger chest size. I usually go for medium, but with a smaller chest I sized down based on other reviews. The fit is flattering and is in that sweet spot (where you don’t want a crop top or those longer, traditional tops).
If you’re like me and have the extra armpit folds, I recommend this top because it doesn’t chafe or make this area obvious. I felt confident during my workouts.

New Favorite Top

I love Janji tank tops and this may be my new favorite! The fabric is so soft and comfortable. The top is flowy but also has some stretch to it if you want to go down a size for a more fitted look.

Love this tank

This is a great versatile tank for running, hiking or everyday. I really like the fit and length of it which hits just right. The Runterra fabric is awesome (I have the tees and long sleeves too). I bought the jasper color and plan to get more!

Great versatile tank!

Light, comfy tank with a great cut. Wore this mountain biking and running and it was perfect. I have the Mineral color and can't wait to get more.

great tank!

I got this tank earlier this summer and LOVE it! It has a flattering cut and isn't too tight or too baggy like a lot of other brands. I need to order in another color!

Nice cut, nice color

I love the cut and color of this top! I have it in Jasper and have loved wearing it for hikes and runs. The cut of the shirt is perfect.

the tank top we've all been looking for

I LOVE this tank! It serves so many purposes in my wardrobe and the cut/fit is just right! The neckline stays put, the armpits don't rub, and the length is just long enough to front tuck without being too long to become unflattering. THe material is lightweight and a great running/hiking top for long days out. Dries quickly and doesn't stick to the skin!
