Features
The NU Arm Cooler Sleeves can lower your skin temperature by 2-3 degrees through skin contact from the permanent Nano Jade Powder embedded inside the yarn.
Iceberg Dry technology is a moisture wicking technology created exclusively for NU to absorb and wick moisture quickly and evenly to achieve the most efficient evaporation possible to keep you comfortable and dry.
As well as keeping you cool, the NU Arm sleeves provide a high level of sun protection.
The sleeves are available in two sizes:
| Size | Sleeve Length (cm) | Arm Width (cm) | Wrist Width (cm) |
| Small/Medium | 40 | 11 | 7 |
| Large/X-Large | 40 | 13 | 8 |
