A lot of people have been mentioning that when they try on the Base Runner Long Sleeve that the inner arm seams feel really scratchy and that they like the top but are passing based on that. A reader that purchased the top and initially liked it a lot had to take her top off to have a closer look at the seams to see what was irritating her. She discovered that the inner seams all have plastic ribbing inside just like the problem of Studio Pants and last summers Play In The Sun Shorts which had the plastic reinforced seams that pocked through. They honoured returns on those pants as they were considered 'defective'. What the hell Lululemon?? What is the point of the 'chafe free flat lock seam' claims that supposedly give you the edge over competition if you are now going to put in plastic seam supports that create an even worse problem?
