A comfortable, round neck talit katan in a wide range of sizes.
Adult sizes are all cotton. Childrens sizes 1 to 7 are polyester and cotton. All measurments are in inches. All Tzitzit are meyuchad.

The wearing of tzitzit is a positive commandment from the Torah: Numbers (15:37-41)
The Lord said to Moses: Speak to the Israelite people and instruct them to make for themselves fringes on the corners of their garments throughout the ages; let them attach a cord of blue to the fringe at each corner. That shall be your fringe; look at it and recall all the commandments of the Lord and observe them, so that you do not follow your heart and eyes in your lustful urge. Thus you shall be reminded to observe all my commandments and be holy to your G-d. I the Lord am you G-d, who brought you out of the land of Egypt to be your G-d: I, the Lord your God.
