Christmas is a time of celebrating the birth of Jesus Christ the son of God, The Star of Bethlehem represents to all who seen it his coming.
Luke 2: 12-14 KJV
12 And this shall be a sign unto you; Ye shall find the babe wrapped in swaddling clothes, lying in a manger.
13 And suddenly there was with the angel a multitude of the heavenly host praising God, and saying,
14 Glory to God in the highest, and on earth peace, goodwill toward men.
A bit more formal than a standard-issue t-shirt, the ultra cotton long-sleeve tee is a clear comfort winner. The sleeves also act as a nice frame. There are no side seams. The shoulders are taped for improved durability. This makes for a good fitting around the shoulders and neck. The cotton used for these shirts is environmentally friendly.
