PerfTzit Undershirt Tzitzis, Adult Round Neck Keshiras Ashkenaz

PerfTzit is the undershirt style — a full t-shirt beged rather than a poncho. It is stitched down both sides about 3.5 inches from the armhole and left open below, so the sides breathe and the corners hang free. The corners are reinforced with a cotton lining, and there is an opening at the top made for tucking the strings in before the beged goes in the wash. 100% cotton throughout, round neck, keshiras Ashkenaz.

Sizes 18 through 28, with meyuchad strings included or ordered bli. Sizes here are approximate: this fits like a shirt rather than like a traditional beged, so a man used to the poncho cut should think in terms of the size he takes in an undershirt.

Men move to PerfTzit for the same reason they wear an undershirt at all — it stays put. Nothing rides up over the shoulders, nothing flaps under a dress shirt, and one garment does the work of two. The string-tucking opening is a small thing that keeps the strings out of the wash cycle, and it is the detail people mention first after the first month.
