All I can give now is first impressions: ONNO is an amazing company - two large t-shirts were ordered. Both were a little too tight for wearing during the summer. Ordered an x-large which fitted much better. The two originals were re-ordered in the x-large size. I then emailed ONNO about returning the two large t-shirts. All correspondence was quick and cordial (working with Narie was a pleasure). Instead of further overloading USPS, they asked me to donate the two t-shirts to someone in need (they were donated). Now, this is first rate customer service! Both t-shirts are VERY comfortable, though one is thicker (warmer) than the other … need to compare composition of the t-shirts to tell which is which from the tags with respect to ordering more (in the future). Wearability/durability - too early to tell … ask me again in six to nine months.
