A sports utility stroller includes a boundary frame including a top and bottom frame to form a playpen cavity therebetween, a stroller frame including a pair of side frames, which supports two sides of the boundary frame, each including a first side frame leg and a second side frame leg pivotally connected with each other, and a pair of locking arrangements for securely locking up the two side frames so as to retain the boundary frame at an unfolded position, wherein at the unfolded position, a top frame is lifted up from the bottom frame to form the playpen cavity having a predetermined depth, and at a folded position, the first and second side frame legs are pivotally folded to drop the top frame towards the bottom frame, so as to minimize the depth of the playpen cavity.
