Merrell Dualtrek Shirt Review

Posted: August 15, 2010 in Uncategorized

Long mornings on the trail require versatile equipment; you’ll be wearing the same stuff under late morning heat at 11AM that you started with in the fog and chill of 5AM.  The fewer wardrobe changes you need, the better – which is why the arm warmer strategy is so popular with ultrarunners.  Merrell’s Dualtrek offers this versatility in a style that’s both comfortable and fashionable; it’s the ultrarunner’s trifecta.


Royal/navy color combo; gray/black also available


  • 100% polyester with Opti-wick moisture management
  • 30+ UPF
  • Stretch mesh body
  • ½-zip collar for ventilation
  • Lycra stash pockets for arm warmer or gel storage
  • MP3 pocket
  • Silicone grip on ends of arm warmers

Merrell Dualtrek Shirt Review

The Dualtrek are cut a little loosely and provides good sun coverage and prevents chafing or hot spots, perfect for the long hours on the trail.

It’s also comfortable at a wide range of temperatures. Merrel’s Opti-Wick fabric moves away moisture from the skin fairly quickly for optimal ventilation.  The zip collar provides even more air movement for hot days.

Good Dualtrek

  • Great temperature regulation in a wide temperature range
  • Outstanding comfort with multi-hour use
  • Very effective ventilation for warm temps
  • The royal/navy blue scheme is pretty good looking, isn’t it?

Bad Dualtrek

  • mp3 pocket could be bigger, or just used as a key pocket
  • I’d prefer a wrist-length arm warmer

Bottom Line: Merrell Dualtrek

If you plan to stay on the trail from “cool and foggy” to “bright and warm” – or vice versa – Merrell’s Dualtrek is a very solid option to serve you well in both conditions.
