Quality issues - Mountain Equipment Eclipse Hooded Zip Tee - Mens

I received the Eclipse beginning of December in Dominican Republic, for a use in the alps in 2018 and wore it so far three times mostly at night, despite the higher temperature here (we have even at night over 20 degree Celsius) and the eclipse has been very nice to wear and looks good. After hand washing i.e dipping in the pool I turned it inside out to dry and realized the seems on the bottom and the arms have been coming apart.
It is a very comfy and nice Fleece, and transports humidity well. I like it a lot, but i am very disappointed to see the defect on the seems. This is not what I expected - I have the competitive Mammut Eiswand light Zip Pul, and in comparison it seems to have a much better stitching.
