I have purchased several of these t-shirts in the past. Until recently, I was very pleased with them. However one of them developed a fault - the stitching came undone on the bottom hem after only around 4 or 5 wears. I contacted the seller, politely asking for a replacement or refund; their answer was no. I contacted Amazon and their response was the same.
I'd only had the t-shirt 2 months. I think it's unreasable to expect an article of clothing to last just a handful of wears before falling apart. Clearly, Team South West and Amazon don't, so bewarned.
EDIT - Shortly after posting this review, Amazon offered me a refund.
