Absolutely LOVEEE these shirts!! I bought four of the organic viscose bamboo/organic cotton shirts a few months ago and got two more on top of that at a later date. I was excited to see that the company provides an extra small option. This was a rare purchase for me to begin with. I'm typically a huge advocate of avoiding new products as much as possible. Besides for these shirts, the rest of my wardrobe is comprised of secondhand pieces that I bought at thrift stores, swapped with relatives, and a couple of pieces came right out of a company dumpster because they had thrown perfectly good items away. I made an exception to support Onno since, as far as I can tell, ethical practices and sustainability are genuinely valued at this company. I work as a farm-hand, and some friends and I volunteer with rescue animals and do community trash-pickups; needless to say, I am outside A LOT! ...and these shirts have held up wonderfully. They are so easy to dress up as well if you are needing a casual outfit when you are out and about. I currently own ten shirts, and six of them are these Onno T-Shirts. I wear one of these the majority of the time. They are extremely soft as well! I have been wearing and washing these shirts for months now, and they have yet to have an odd crease appear in the sleeves or at the bottom like I have seen many times with other shirts. I started off washing them in cold water and air drying, which works perfectly; however, I have washed them in warm water and put them in the dryer a few times as well since I didn't have as much time. Both ways are effective. Just know that if you use warmer water and place them in the dryer, they are going to shrink a little bit; the company is very clear and direct about that which is amazing! Lastly, a huge shoutout to Elyse, the awesome person in customer service who took time to help me out and answer a question. He/she/ze was super friendly and responsive, and deserves a spotlight for their uplifting personality. Thank you, Elyse! Hope some good vibes come your way. :) If you are looking for a more sustainable, minimal, practical, and comfortable shirt, then I confidently recommend!!
