Sample 1:
Type 3 as described here: http://www.wehrmacht-awards.com/Forums/showpost.php?p=2944510&postcount=29. The T-shirt is 1970’s style, so it is meant to be worn tight. T-shirt was probably meant to allow the wearer to keep cool and comfortable in the heat and it has a different pattern than the print on jackets and other “heavier” items.
