"When living and working in the extreme that is Antarctica, you learn the absolute importance of layering. You simply can't afford to not get it right. This environment is totally unforgiving The most important part of layering is the quality of each layer. That's why my first choice for a base layer is Merino Country hands down. The fit is spot on and they stay where you want them to stay." DANNY, Antartica
