Why Synthetics aren't as good as Down
Down provides approximately three times the warmth per ounce compared to even the best synthetics, which can mat and lump together. Over time this can leave empty cold spots, while down continually re-lofts and moulds itself to the body.
Benefits of Down
Down has the marvellous ability to breath and “wick away” body moisture, which keeps the user, dry and warm. Most synthetics do not allow perspiration from the body to escape to the outside, therefore the user experiences clamminess and becomes cold.
Down is also the most eco-friendly product on the market, as everything from harvest to final production is a practice in eliminating waste. All by-products of the processing are biodegradable and the product itself is naturally occurring. The difference between the Synthetics and Down in respect to their carbon footprint is staggering.
Ounce for ounce, down is the warmest insulating material available and given the proper care, should last as long as you do. You can wash it, dry it, scrunch it up tight and it always bounces back to its original fluffy form.
