Heerlijk voor crossfit en fietsen

Heerlijk zittend shirt, met mesh achterkant die prima werkt met rugzak op fiets. Normaal zweet ik redelijk snel maar met dit shirt kan ik heerlijk doorgaan. gelijk nog een exemplaar besteld.

zu lang, zu glänzend

nicht schlecht, aber leider etwas zu lang und zu glänzend..,

The perfect fit

So this shirt to me is the perfect fit for the man with a (more or less) athletic body. A bit tighter around the chest and arms, but still breathable. Perfect for your everday fitness, run, or tactical purposes. I got the black and green color in M size and they’re great. Well done Under Armour!


Awesome fitting and style, usually i am a large, but for UA i take a Medium, the pictures colors are the same as the originals and yes i will recommend this product.

Just what I was looking for

Perfect fit with a good length. Fitted on the arms and chest and loser going down so great mobility and flexibility. It also remains breathable after long workouts in high temps. I'm currently waiting on my 2nd one to arrive!

Nice and light

So I usually get a size down. So for the UA Tech shirts, I tend to get a small. This is quite tight fitting so I got a size up, so a medium and it fits me perfectly.

Super cool shirt met perfecte kleur groen

Pasvorm is perfect, de stof voelt comfortabel en het is dé kleur groen waar ik al een tijdje naar op zoek was.

mk1 shirt

FAB Shirt- great fit and the green is an amazing colour

regret buying it

I usually buy the tactical shirts and it fits a little loose, this shirt runs tight,,,, wasted my money
