The main theoretical and experimental results of the study of magnetic skyrmions in films of isotropic chiral magnets are considered. A significant part of the paper presents new results that were not included in previous monographs and reviews. Skyrmions are formations characterized by a quant„ized topological number. They attract considerable attention of researchers due to their dynamics in external fields, which has promising features in terms of applications in spintronics. Special attention is given to the structure and interaction of 3D skyrmions, and a new magnetic structure - the chiral bobber - is considered.
