In Patagonia there are only small seasonal changes in the temperature regime in contrast to the same latitude in the northern hemisphere, but “all the seasons can be observed in a single day”. Weather change very often here. In active excursions, we will be exposed to the elements.

Clothes Layering

What’s the secret to staying warm and comfortable in the outdoors? Clothes layering. Layers allow you to build a tiny microclimate that surrounds your body and can be adapted to moisture, wind, temperature, and exertion. At les three layers are nesesary:

Base Layer

The inner-most layer is critical because it’s in direct contact with your skin. Base layers (also known as underwear) should transport moisture away from the skin and disperse it to the air or outer layers where it can evaporate.

The best base layer materials are synthetics (polypropylene and polyester). These are light and strong, absorb very little water, and are quick to dry. Base layers should fit snugly without being constricting.

Base layers are available in light, medium, and heavy weights. Light layers suit aerobic activity where sweat dispersal is paramount. Midweight underwear provides moisture control and insulation for stop-and-go activities. Heavy layers are best in very cold conditions, or when you’re relatively inactive.

Mid-Layer

The mid-layer provides insulation and continues the transportation of moisture from the inner layer. To slow heat loss, this layer must be capable of retaining the warmth generated by your body. Wool and synthetics are well suited to this because the structure of the fibres creates small air spaces that trap molecules of warm air.

Additional features, such as pit zippers and full-length front zippers, allow venting. As with the inner layer, this layer should be snug but not constricting.

Outer Layer

The outer layer protects you from the elements and should allow air to circulate and excess moisture to escape. For dry conditions, a breathable (uncoated) wind shell or a smooth-surfaced soft shell may be all you need. If you expect conditions to be more severe, a waterproof (coated) rain jacket might be adequate. A shell made of a breathable and waterproof fabric, such as Gore-Tex, will protect you from wind and rain, and allow water vapour to escape.

 Stay warm & comfortable, wearing smart! and Enjoy Patagonia….
