Adidas Terrex half-zip tee trail running t-shirt review

10:19 12th June 2013 By Andy Wilson

The Terrex is a heavier weight tee, ideal for cooler days. The 50+ SPF might be a nice feature, but you won’t be wearing this in the heat of summer, as the weave is pretty thick. However, it’s not short of pleasing features and the higher neck feels comfortable, particularly when running with a pack.

Adidas Terrex 1/2 Zip t-shirt

Available in colours other than something that so closely resembles the Spanish football team strip.

Terrex has made a name for itself in outdoor gear over the past few years, and this half zip tee is a solid offering. Although the red and yellow design is a bit too ‘life guard chic’ for our liking, the fit is comfortable enough. The seams don’t seem too intrusive and the fit is close without being too figure-hugging. Even on long runs in very sweaty conditions, the seams didn’t rub.
The arm length is ample, and the zip pulls low enough for a good bit of air circulation on a sweaty climb, but really this jersey is for cooler weather runs. The double weight collar stands fairly high up the neck, which feels comforting against your skin, particularly when the zip is done up. The neck was great when running with a pack, which can often leave a nasty rash when it rubs around your neck and shoulders. It would be a good choice for a long, steady run in the English summer (i.e. cool!)
The wicking performance of the Cocona fabric wasn’t as good as some of the others in the group test, but it dried reasonably well for a heavier weight shirt. Only in hefty humidity would you find it a problem.

↑ The Good:

  • Nice high collar prevents chafing from a pack.
  • Zip provides good air flow in the heat.
  • Red always makes you go faster.

↓ The not-so-good:

  • Yellow trim is a bit too Baywatch.
  • Drying speed not as fast as some.


A decent shirt but perhaps you’d expect more for the money (can be found online for cheaper though). The fit is a winner, though and we say always go for substance over style.

Score: 7/10
