We're going to look at base layers, discuss all the differences and figure out what's best for what conditions. Base layers are worn against the skin and they serve two primary objectives. One is to provide temperature regulation and two is to work moisture off your body and evaporate it into the atmosphere. In cold weather you want your base layer to work the moisture off your body and evaporate it into the atmosphere as well as provide a little bit of insulation. You want to stay as dry as possible in cold weather so that when you stop you don't chill down and get really cold. In warmer weather you also want your base layer to work moisture keeping your dry and comfortable. You need this layer to be really breathable so you don't overheat. Starting off with cotton, a lot of people make the fatal mistake of wearing cotton under their hunting clothing. Cotton absorbs a lot of moisture, doesn't let it go, takes a long time to dry and it gets really heavy when it's wet. Worst case scenario is you get caught out in some bad weather and end up hypothermic. Because cotton holds onto the moisture and not allowing it to evaporate it renders all your fancy technical hunting gear on top of it absolutely useless. We can't stress enough that there is no place for cotton in an outdoors environment. The wool has an advantage in that it will keep you warm even when it's damp but it does hold a lot of moisture taking a long time to dry. And when you stop in a cold environment you will chill down very quickly. Wool is not as durable as a synthetic base layer but it does have a natural inbuilt antimicrobial property. Although wool is a great base layer, technological advances in synthetic fibers have tipped the scales in favour of synthetic base layers in an outdoor environment. Synthetic fibers are hydrophobic which means they absorb very little moisture. Through a special knitting process we can create a fabric that works moisture very quickly and allows that moisture to evaporate off the fabric, leaving your skin dry and comfortable. We have designed all our base layers with body mapping. This means we've matched different parts of the body to specific fabrics based on their technical attributes. Things like high working, high breathability fabrics under the arms, high stretch fabrics across the shoulders and through the knees, and insulating fabrics on the core of your body. Starting off with the core plus, this is our coldest weather base layer. The core plus has a grid fleece backer giving you a little bit more insulation for when it's really cold and nasty in the depths of winter. Next we have the core range. Now this fabric is a little bit lighter than the core plus so it's not as suitable in really cold conditions. It's more suitable for milder temperatures. The main reason you're going to be buying the core range is for its wicking ability. It achieves this with a close fit to the skin, allowing the fabric to immediately absorb your sweat and from there evaporate it out into the atmosphere. Moving on to the crux top, this garment is designed for warmer weather. The looser cut allows air to circulate freely, keeping you cool, and the mesh in the underarm area dumps heat quickly and readily. We've used a special synthetic fiber here that's infused with bamboo charcoal. Bamboo charcoal has special wicking and antimicrobial properties. This means you can wear it longer without it getting stinky. The crux top has a quarter length zip to help you dump more heat. It has a high collar and long sleeves to protect your skin from the sun. The crux T has the same fabric and body mapping as the crux top, just as short sleeves for those who would rather wear a T-shirt. Finally we have the vanzitruti. This uses the same fabric and body mapping as the crux range. We've included thumb loops, a face mask and a hood for greater sun protection and concealment. Our sustainability promise is a huge priority for our company. That's why all our base layers come in recycled, compostable packaging.
