care instructions

Wash cold with like colors

Machine dry low or hang dry for best results and lifespan of the garment

Heads up — Runterra is not pre-shrunk

We have relaxed the body and slightly lengthened the sleeves of this top to accommodate for some shrinkage which may occur in the wash cycle since Runterra is made from a majority natural fiber.

Avoid washing and drying with high heat.

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.

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.

Super soft shirt

Love the shirt for everyday casual wear. Super soft and comfortable. I received my first Runterra LS as a gift. Sleeves ran a bit long, but I liked the material so I bought a second one (a size down) for myself and the fit is great! I’m looking a Runterra SS now that the weather is warming up.

love this longsleeve

I ordered this in size medium and was stoked with the fitting. I've taken it out for long runs on the road and on the trail with without a layer underneath and it fit well untucked. I mention untucked because I found that when it was tucked in, the large graphics on the back sticked more to my skin when sweating or in the rain. I wonder if it has to do with the amount of ink or the ways the graphics were screened on the shirt that it creates this feeling. If worn normally, I found that this occurred less so when not tucked in. Other than that little detail, the shirt feels great!

Amazing fit and feel

This is my first Janji piece. Totally loved it. The feel of natural fibers is unbeatable.

Great fit long sleeve

Lightweight long sleeve t-shirt great for the cooler NC morning in the winter.

New LS Convert

I've never liked running in LS before. In the past, I would just rather take a light jacket. But this fabric makes me think differently. Very breathable and soft. Yes the sleeves are very long, but I just tuck my hands in them when I'm cold and scrunch them up when I'm too hot. Perfect piece for those transition weathers, and a great layer to add to your colder runs.

First spin

Hey all, just got off my spin bike and what can I say?!? This new Runterra is fantastic. Fit was great, felt comfortable even when sprinting. Can’t wait to take it out on the road for my next run! Well worth it, and awesome color a d design!

New long sleeve fave

I absolutely love both of my runpacas (midnight and salar) but this new release is my all time favorite long sleeve. The color is gorgeous and I love the hemming on the shoulders/arms. It’s soft, lightweight and sits comfortably under the arms when running without constricting anything. At 5’10” I sit between a Janji medium and small in tops but generally go with the medium.
