Brynje Base Layers Explained

If you’ve never worn mesh before, get ready to rethink base layers entirely.

When it comes to ultralight hiking, every gram matters—but so does comfort, breathability, and performance in tough conditions. Enter Brynje of Norway, a legendary name in base layers, trusted by Arctic explorers and alpine athletes. For the ultralight community, two standout ranges deserve a closer look: Super Thermo and Wool Thermo.

Wait, how does Mesh technology work?

The mesh construction ensures effective transport of excess moisture and heat away from the body and regulates temperature by allowing air circulation at times of high activity. At times of low activity and periods of rest, the mesh cells retain warm air, forming an uninterrupted layer of insulation next to the skin.

Key Benefits 

• Lightweight Warmth - The mesh traps a layer of warm air next to your body without adding bulk, offering outstanding insulation for the weight.

• Fast Drying - Brynje mesh dries significantly faster than traditional solid-weave base layers.

• Temperature Versatility - Mesh adapts well to changing conditions—cool when you're moving, warm when you're still—making it ideal for variable climates and active pursuits.

• Proven in Extreme Conditions - Trusted by military units, Arctic explorers, and mountain rescue teams—this is gear designed to perform when it counts.

Super Thermo - The original and best-selling synthetic mesh base layer

Super Thermo creates a layer of trapped air close to your skin, delivering impressive insulation while allowing maximum moisture escape. The result? You stay dry, warm, and comfortable even during high intensity activities.

Made For: High and low intensity activities, in cold or wet weather. 

Wool Thermo -Mesh Meets Merino for Natural Warmth

Brynje’s Wool Thermo range adds a merino wool blend to the same mesh design, combining the thermal regulation of mesh with the odor resistance and softness of wool. It’s a hybrid that excels in multi-day missions where layering flexibility and odour-resistance are key.

Made For: Ideal for medium to low activity, in cool or cold weather.
