Our XL blocks of Coconut Coir are Triple Washed, 100% Organic, and has low EC and pH balanced, making it the perfect addition to your growing medium

Coconut coir growing medium comes from the coconut's fibrous husk (known as coir) that is bound together by lignin (known as pith). After the husk is immersed in water for 6 weeks, the fiber is extracted mechanically, and the pith is left behind as a waste product and stored in heaps to age. Since the pith comes from the fruit, it is quite naturally rich in nutrients. Coconut coir growing mediums are dehydrated and compressed into a compact form for easy handling. With the addition of water, coir expands to an easy to work with growing medium. 

Expands to up to 20 gallons of material

Runs small
Size: XX-Large, Color: Navy
Definitely go a size up. These run a whole size smaller than designated. Material is also heavier than a regular t-shirt. Quality seems okay

Fits well and comfortable!
Size: Large, Color: Eggshell White Black Mariner Stripe, Size: Large, Color: Eggshell White Black Mariner Stripe
This shirt fits my husband very well, it is true to size. It is soft and stretchy enough to be comfortable. I bought this as part of a costume but my husband wears it around the house now because it's so comfy.

You get what you pay for
Size: XX-Large, Color: Eggshell White Black Mariner Stripe
Like most of the other reviews here, the shirt runs too small and too short. Material was also incredibly uncomfortable. It also wasn't the color I was hoping it would be, but that's on me for not reading the fine print (eggshell white was very much not white) If you're looking at this for a certain costume/cosplay idea, it's probably not what you're looking for.
