Thermowave Merino Baselayers Product News

​​​Who We Are

Based in Kaunas Lithuania since 1928, our organisation has been developing high tech textiles for industry and base layers - predominantly using the finest grade Merino yarns - for a variety of activities including deep-sea dives and even space missions.​ ​​

During the last 15 years, we have applied this experience, the hard won knowledge and exceptional craftsmanship to outdoor apparel and created Thermowave.​ ​​

By taking the finest natural Merino and man-made fibres, often in unique innovative combinations, Thermowave has created a series of extraordinary textiles that offer superb performance and comfort for outdoor enthusiasts.

Merino Xtreme

Directly descended from textiles developed for space and dive programmes, Thermowave Xtreme garments combine in a dual layer system the finest wool that mother nature can provide, together with the highest quality synthetic yarns.

Merino wool has supreme insulating qualities and is naturally anti-bacterial. The combination with soft, wicking polyester makes Xtreme garments very warm yet remarkably breathable – as such they are suitable for intense activity in cold to very cold conditions.
