The old quiz (which asks for height and weight) recommended the XS size. I’m slightly disappointed because it feels a bit too tight. The new quiz seems to be more accurate.
Additionally, the print appears more offset toward the bottom of the T-shirt, which doesn’t look as pleasant as it does in the product page photos – probably due to the XS size.
It would be really helpful to know the parameters and T-shirt size that the model wears on the photos.
+ Great fabric and print quality
+ Blazing-fast delivery
- Weird print placement on the back of the T-shirt
- It's easy to miss the size with the old quiz. Shouldn't be a problem now

The cotton and print quality is excellent, it is a bit thicker than I expected though.
From the mag dust to the clothing it’s all top notch! I believe Magnus truly cares about what he puts out in the world.
Everything was great.
The quality of the shirts I purchased is just outstanding. They are thick and feel great. The printing is thick and vibrant. Customer service was the best I have ever worked with. Wore them climbing up in Duluth MN and they held up great.
Really nice shirt, I'd buy another one if it wasn't always sold out!
Great design. Good quality.
Shirt was as presented on YouTube and website. A really cool tee. Slight delay with dispatch of shirt due to high demand over Christmas period. I wish i had been notified of the delay as it was me chasing, but it was all good, and all worked out. Communication with Rúngne was prompt and kind. The shirt was a present and got to me in the nick of time, just before Christmas. Thank you Rúngne ✌️❤️.
Love the fit of this shirt! Slim and long through the torso and snug on the arms. Also, probably the highest quality shirt I own. You know it will last a long time.
Good quality,and fast delivery. Also friendly and fast responding costumer service.
Fit is very form fitting….
Nice T-Shirt. Cotton is good quality and delivery was quick even though from Norway 😄
Monkey Index Tee är en riktig fullträff för den som söker en kombination av stil, komfort och funktionalitet. Med sin utmärkta passform, höga kvalitet i ekologisk bomull och det snygga ap-trycket av Robert Høyem, är detta en t-shirt jag varmt kan rekommendera.
High quality shirts and sick designs
Lovely material! Initially I was a bit concerned as is a little bit long but in fact makes it more comfortable when climbing.
Love the design and it feels super comfortable, my new favourite t-shirt. For reference I’m 1.60cm tall and went for size S
The shirt feels and fits perfect!
It’s both stylish and has a great fit. And the quality is good.
It is a stunning graphic and a good quality tee. Size was a bit snug on me so dont necessarily trust the size calculator.
Great T-Shirt - quality and comfort
I'm not really sure who this is cut for... I'm about 5'9", 165lbs and a size medium in Patagonia fits me perfectly. I ordered a size large it is both too long and too tight in the neck and shoulders. Maybe this would fit a stereotypical skinny climber's build. With the $25 international return shipping there's no point in returning... The graphic is cool and the materials seem nice enough.

Monkey Index Tee Regular Fit
Bought as a gift for our Teenage son. XL fits him how we wanted. It is long over the shoulders, (“baggy”) but not a tent around his torso. Quality fabric, great print. He is 5’,10”, 160lb, athletic build.
Does not fit like the size guide outlines. Too expensive to return. Will not buy again

I've always been self conscious of my long arms, but now I can be proud of my genetic freakishness with my very own Monkey Index shirt. Need that box off the top shelf, I got you. Need to recreate hands across america with the fewest number of people, sign me up dawg. Your mom need a hug that doesn't terminate half way 'round? I'll hook her up.
Soft comfy t shirt however it was little too tight around the neck and i prefer more open cut
Good shirt and great quality. Would definitely recommend
I like the fabric alot. Looks dope.
