In short
Good for
- Cold-weather layering, and warm-weather wear on OEX's wording
Strengths
- Flatlock and offset shoulder seams to cut chafing under a pack strap, per OEX
- Thumb loops
- 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
- OEX says merino takes a little more care than synthetic
- 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
