Perfect Shirt

Super soft and breathable. Extremely good fit, I’ll definitely be buying more.

Sweet Tee

Nice fit, great value, looks awesome on, like the colour.

Review of the Threadbone Siro T-Shirt

I purchased this shirt to go on a quick Trip, it fit well and was very comfortable. In fact I now use it as one of my go to shirts for exercising. It has a very good fit and a comfort that I do not find in all of my T-Shirts.

Threadborne is Threadbear

The Threadborne material is so thin it is see through.

Its good

The shirt is really good and fabric is soft but the seam around the shoulder can be much better.

Not Happy with fabric

I was not happy with the fabric of this shirt. I found the fabric very thin (almost see through) and just after 1 wash it pilled quite severely! I love Under Armour and usually quite happy with my purchases, but not with this shirt.

Great quality, runs a bit larger

I've come to realise that UA shirts run a big bigger than the normal brand - so it was a bit roomy but still great nonetheless.

Light weight, Comfort

Purchased for my son, Comfortable, Light weight, nice colour

Not bad but not great either

Not a shirt for guys who build muscle. The sleeves are too small and too right - they rise up the bicep when lifting. Furthermore the shirt itself is somewhat too big and loose, almost like too much fabric was used? I’m 5ft 6 and bought a small - I have since stopped using this shirt and consider it a poor purchase

Great Quality Shirt

While UA Tech shirts have lost their touch that made them excellent years ago...Siro picked it up. These Threadborne shirts are actually solid with respect to the material, comfort level, performance, and appearance. The shirt does run a little too big but either way it's an excellent choice.
