Effort's Eco-Essentials well-made bamboo shirts are super soft, comfortable and have an ahhhhh factor that's irresistibly alluring. It's said that bamboo is anti-fungal and odour resistant, which can lend itself to being naturally great for work outs and as a summer shirt.
Bamboo is sometimes known as the vegan cashmere, no animals are used to make it and it's so soft it's reminiscent of cashmere, but luckily, it's machine washable.
The farm grown, fast growing bamboo plant, absorbs carbon dioxide from the air and releases oxygen, it requires very little water, without using pesticides or chemical fertilizers. Bamboo is a rayon which is considered a semi-synthetic, as it goes through a manufacturing process that turns the wood into a soft fabric.
Effort's Eco-Essentials (est. 1994) was one of the first to introduce bamboo as a fabric/clothing and have expanded into different combinations of bamboo with organic cotton and some with spandex. From fitted T-shirts with spandex that hug the body to T's with a relaxed fit that are rayon from bamboo/organic cotton. Also, in the collection of bamboo clothing are yoga pants and knit sweaters for men and women, golf/polo shirts and boxers for men and leggings, dresses, skirts and shorts for women.
