I've found a review of non-iron shirts originally published in Consumer Reports (February 2010). The full review is not available unless you are a subscriber. Still, you do get some useful information from the summary - see http://bit.ly/JKguax. Also, in March 2007, there was a review of wrinkle-free shirts, but no more information regarding this test is available for free on the site. However, there are numerous University libraries in Sweden that holds an electronic subscription to Consumer Reports, as you can see here: http://libris.kb.se/bib/2723197 . My advice is that you contact your local public library for further help. They can assist in ordering a copy of these articles. There might be a small fee for this service. I might add that I've not been able to find any reviews specifically covering the Swedish market.
