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.
- 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.
- 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?
- 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.
