For boys of all ages and sizes who aren't up to the rigors of re-tying their tie every time they need to wear one for a formal occasion, Absolute Ties simplifies their dilemma with boys zipper ties in three lengths and an inordinate number of unique designs and colors. A zipper tie looks like a conventional tie, but it has a permanent knot like a clip on tie. The difference is that the zipper tie has an adjustable band that goes around the boy's neck to keep the tie securely in place. The size of the loop is controlled by a zipper. Adjusting the zipper tie is an easy process; to start, take hold of the small end of the tie and the knot. Once you have done so, you can slide the zipper up by holding the small end firmly and sliding the knot up.
