Characteristic predictions of chiral soliton models (the Skyrme model and its extentions) are discussed. The chiral soliton model predictions of low-lying dibaryon states qualitatively agree with the recent evidence for the existence of narrow dibaryons in reactions of the inelastic proton scattering on deuterons and the double photon radiation pp \rightarrow pp \gamma \gamma. The connection between magnetic moment operators and inertia tensors valid for arbitrary SU(2) skyrmion configurations allows us to estimate the electromagnetic decay width of some states of interest. Predictions of a different type are multibaryons with a nontrivial flavor (strangeness, charm or bottom), which can be found, in particular, in high-energy heavy ions collisions. It is shown that the large-B multiskyrmions given by the rational map ansatze can be described within the domain-wall approximation or as a spherical bag with the energy and the baryon number density concentrated at its boundary.
