We study the cycle structure of I-tough, triangle-free graphs. In particular, w e prove that every such graph on n 2 3 vertices with minimum degree 6 2 i ( n + 2) has a 2-factor. W e also show this is best possible by exhibiting an infinite class of I-tough, triangle-free graphs having 6 = $ ( n + 1
