Macpac Prothermal Polartec® Long Johns — Men's
Why we made this
A technical baselayer made from Polartec® Power Grid™, the Prothermal Long John 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® Long John 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.

Best alpine baselayer, Toasty warm on thebelays and sheds the heat while climbing the pitch. I'm 6'2 and the length is good for the large. Highly recommended.

Great material but.....
Fantastic material, it really works. I have the top in medium which fits fine but the pants, even in small, are way too long. I'm a 5'10 guy and I could chop off a good six inches of leg length before they fit. The sizing needs a review. I take medium in everything else I own from Macpac
