Easton's 1897 Bible Dictionary:

Fleece
   the wool of a sheep, whether shorn off or still attached to the
   skin (Deut. 18:4; Job 31:20). The miracle of Gideon's fleece
   (Judg. 6:37-40) consisted in the dew having fallen at one time
   on the fleece without any on the floor, and at another time in
   the fleece remaining dry while the ground was wet with dew.
