Model predictions of Strangeness S=-1 dibaryons are reviewed, along with published experimental searches. The I=1/2, J(P)=0(-), K-pp quasibound state is a recent example of a coupled-channels s-wave dibaryon driven by the upper channel. The talk will focus on a recently proposed I=3/2, J(P)=2(+), pi-Lambda-N quasibound p-wave state driven by the lower channel [Gal-Garcilazo, PRD 78, 014013 (2008), and Garcilazo-Gal in preparation]. Implications to current kaon-nuclear studies will be discussed.
