This pajama set is a great transition into fall and winter. A matching set is always great and convenient. This set includes a solid short sleeve V-neck top and matches the open bottom lounge pants with the plaid pattern. The fabric is soft and comfortable with a flannel, warmer feeling bottom that are great for the cooler months. There are several details in this set that make it a great quality. The set features side seam pockets, adjustable drawstring, and elastic waistband for a better fit. We love a good pattern, and these plaid pants are a classic, casual pattern. This set can be worn to sleep or just lounging around the house. This is such a giftable set that would be great for your son, husband, grandpa, or father.
