Estimate from maker's specs

In short

Good for

  • Wearing alone as a quick-drying long-sleeve tee
  • A first layer for people who want to try synthetic before spending on merino

Strengths

  • 100% polyester: quick drying, per OEX
  • Polygiene treatment against odour, per OEX
  • Sizes XS to XXXL, a wide size range
  • Sold by three UK shops with 28-day returns

Weaknesses

  • OEX publishes no weight and no fabric weight, so weight and warmth are estimates, not reviewed scores
  • Described as a lightweight technical tee with no stated warmth: not a winter base layer
  • No independent test found, so comfort, odour and durability are estimates, not reviewed scores
  • OEX is the house brand of Blacks, Millets and GO Outdoors, so those shops are not independent sources for it
