The shirt is crafted out of 99% merino wool with 1% nylon that works to give the garment a breathable profile that won't allow odors to develop thanks to its [natural moisture wicking properties](https://www.trendhunter.com/trends/airism-bra-camisole) and ability to regular temperature. The wool in the fabric is sourced from New Zealand and Australia to ensure quality, while the nylon in the mix helps to reinforce the durability of the garment, enhance its water resistance and prevent it from clinging too much. The Proof 72-Hour Merino Air T-Shirt comes in five color options and is priced at $78.
