This is how we get the numbers that we use
our shirts require 1/3 less water
Hemp uses the least amount of water of any natural material used in t-shirt design. It has been all the rage in the last few years and you will likely hear more about it to come. Not only does it require less water but it is a sturdier fabric that will last longer than cotton.
Statistics are always difficult to accurately represent. Estimates of water used to make cotton vary widely from around 10,000-20,000 liters. According to the Textile Exchange, Organic Cotton lint is 14,073 liters/kg on average. Compare that to the water footprint of hemp at 2,719 liters/kg.
Using those numbers, the 55% hemp / 45% organic cotton blend uses around 1000 liters less water compared to a 100% organic cotton shirt.
Although we say 1/3 less water is used, the actual percentage is up to about 42% but we would rather under estimate than over estimate. Cotton is used blended in the body fabric but also as 100% thread, ribbing, and tags. But hemp is only used on the body fabric, thus larger shirts made out of hemp have an even greener footprint compared to large cotton t-shirts.
Hemp and low-impact dyes are safer
Hemp requires far fewer pesticides in general to grow than does cotton, making it a low hassle plant by comparison. Less pesticides used means less buildup on soil or run off into our waterways.
Low-impact dyes are a far safer alternative to the traditional dyes on the market. Low-impact dyes are a type of fiber reactive dye that is Oeko certified to not have toxic substances. While low-impact dyes might currently be the safest option on the market we are looking into more natural dyeing techniques and substances that may be able to replace them.
