M's Run All Day Tee

Been a great lightweight everyday run shirt. I like full sleeve sun shirts for the long days to limit sunscreen use, but this has been great for morning runs and short midday runs for me. Expect to buy more when I need to replace other shirts in the future.

Have gone on a few runs in this shirt now. The fit, feel and finish are superb. My only issue is that it gets clingy when sweat soaked, but that’s going to happen with any super thin light weight shirt. When it’s dry, it’s perfect!

I never want to take it off. Extremely comfortable even when soaking wet.

Great hot weather running shirt

M's Run All Day Tee

Great fit - Extremely comfortable and durable. I'm tossing all my old t-shirts from another brand and replacing them with the RAD tee. I live in a hot & humid climate, and this shirt is a perfect combination of wicking and breathing. Buying 5 more.

This is my third Run All Day t-shirt. I really like them, especially for hot weather because they stay nice and light even when soaked by sweat. Love the different color variations and the minimal branding.

Great shirt and material.

I’ve worn this tee on several trail running sessions in hot, humid conditions, and the quick-drying performance is noticeable — it doesn’t get soaked or heavy even during sessions longer than 90 minutes. The ventilation feels well distributed, and it avoids that clingy, sticky-to-skin feeling I usually get from other shirts in humid conditions. One note: it runs slightly large, so you may want to size down if you prefer a more fitted look. Highly recommend for runners in tropical climates.

This is a great shirt, one of my favorites. The fit is great, the material is great. The thin color is really nice, doesnt irritate your neck

Honestly, these are so good. I have been known to wear my
run all day tee and unhealthy amount of times. I have 6 or 7 of them but still.. haha. These are my go to shirts for gym, trail running and everyday life. Love them, so comfortable. Thanks

I have been wearing Janji products (shorts, pants, caps and packs) for 5 years and have been a big fan. I’ve also recommended Janji to my friends and colleagues over the years.

This is the first time I’ve tried a shirt and what I found was disappointing. My reason for reviewing is not to impact Janji negatively (in case it came across that way) but rather coming from a place where I have high expectations.

Here is a comparison with a Brooks and Patagonia shirts I’ve been running in for a few years. All shirts are running shirts in size small.

Note that Brooks and Patagonia both are consistent in their front side length (24”) and neck width (6”) while Janji RAD runs 27” front length and 8” neck.

Hope this helps.

So for me, this Janji RAD shirt is too big to wear.

I'm relatively new to Janji, and I'm slowly making my way through the various gear options. I have to say this is my favorite tee yet! It's lightweight and doesn't smother you on a hot, humid Central Texas day when you're just drenched in sweat. It's got a close, but not constricting, fit and is also good for a random non-running day. I've got another one on the way.

Only meant for tall runners.
It goes nearly to my knees!
And the neck is so wide, it shows chest hair. Never had an odd fitting shirt as this one.

ok , but not light performance, breathable or moist wicking as other fabrics out there

Great for summer and warm days. Have several versions of the same shirt and nothing else that I own compares.

Really like the close fit the shirt offers and it dries relatively quickly. Would definitely purchase again.

Couldn’t really ask for a better engineered running shirt. A pleasure to wear. Also, in a pinch, doubles as a pretty decent swim shirt. Just tuck into your trunks for added sleekness!

This shirt arrived just in time for hot may running. Fit is perfect and shirt performed excellent in hot Georgia weather.

This shirt has quickly become my new go-to. The material is lightweight but feels more durable than other lightweight running shirts I've tried, so I don't worry about it wearing out. The collar is wide and doesnt rub or chafe on longer runs. The fit strikes a nice balance of loose and airy without being oversized or uncomfortable

New favorite ultra tee. Fit construction is very precise and tightly fitted, but allows for plenty of movement, which is perfect when wearing a belt, vest, or other accessories.

I have both the old sizing from 2025 and new sizing from 2026 and both are great! Be sure to double check the fit range though, as the updates may pertain to you.
