What sets this type of construction apart? What advantages does it offer over traditional knit fabric? As can be found in many sources:
- First, the mesh structure allows for very rapid moisture transfer away from the skin to outer clothing layers, reducing the risk of sweat buildup and overheating.
- Second, the open space creates a kind of natural air chamber system, helping maintain optimal thermal performance across varying levels of physical activity.
In the garment, standard knit fabric is used in selected zones instead of mesh
Mesh is not everything – in the case of Aclima, it is made from wool. This natural material is highly valued for its ability to regulate body temperature, perform well when wet, and retain freshness over time. I own several merino wool products myself, and even after multiple uses with heavy sweating, they remain relatively fresh. By contrast, synthetic fabrics can develop unpleasant odors even after a single day of wear. Wool, on the other hand, can often be worn much longer after simple airing.
Mesh wool base layers are truly worth attention. This is not a new technological gimmick or marketing hype – it is a solution that has been known and proven for decades.
Does Aclima offer anything beyond base layers?
Aclima’s offering goes far beyond base layers. The range also includes products with significantly heavier fabric weights. Among them are lightweight insulating garments, thick technical hoodies, and a wide selection of accessories such as socks and hats. One-piece base layers were also presented at the booth.
