Dynafit Ultra S-Tech Shirt: first impressions
The Dynafit Ultra S-Tech Shirt – as is customary with running gear from this performance-orientated European brand – is very snug fitting by design. Despite the tightness, however, the material boasts four-way stretch, so it doesn’t feel restrictive.
This technical running top is unbelievably light, and the breathable poly material barely takes on any moisture even if you get caught out in the rain, so it won’t get any heavier no matter what the weather throws at you.
On the downside, there’s no recycled material content in this top (no bluesign approval here, for sure), and it hasn’t been treated with an anti-pong/bacteria substance, so odors could accumulate after extended use. You need to be a bit careful how you wash it, too – there’s not much room for it to get any tighter.

Dynafit Ultra S-Tech Shirt: on the trails
Pulling the Ultra S-Tech Shirt over your head instantly puts you in a racing frame of mind; the material mix and very close-fitting cut of this dynamic T means it clings on tight to your torso – which is perfect if you’re in top fighting fitness form and want to avoid snagging on anything while trail running through mountains and woods (but it leaves nowhere to hide if you’re carrying a few extra rations in the belly department).
However, the four-way stretch material used in the construction of the top means it moves dynamically with you when you’re hopping over rocks and tackling other trail obstacles. The lack of flapping fabric also reduces the likelihood of your top getting snagged on brambles and the like, plus it really is more aerodynamic.
The breathability levels on this top are decent, with good mesh elements employed across the back and chest, and the design is seamless, which adds to comfort levels.
