Why we made this
A technical baselayer made from Polartec® Power Grid™, the Prothermal Top was designed in partnership with the New Zealand Alpine Team for performance efficiency — providing advanced warmth and breathability, while also reducing fabric mass.
Designed in partnership with the New Zealand Alpine Team, the Prothermal Polartec® Top is one of our highest performing baselayers. Ideal for climbers and weight-conscious hikers, the Prothermal range is made out of Polartec® Power Grid™ fleece fabric for superior breathability, lightweight warmth and reduced fabric mass for improved compressibility. A minimalist design that maximises fabric performance, the internal grid pattern wicks moisture away from your body during high intensity activity, helping to keep you comfortable for longer. Made with 25% post-consumer recycled content, Polartec® Power Grid™ is bluesign® approved, meaning this fabric has been manufactured with responsible use of resources and the lowest possible impact on people and the environment. Supported by Polygiene® odour control technology, the Prothermal range is intended for multi-day use.
