To create the perfect all-purpose training vest there are three things to consider. Firstly, the fabric: our unique Borgini fabric is light, supple, softer than cotton, and quick-dry. Secondly, the fit: the OM4 is loose but not too baggy; it envelopes your body perfectly with a bespoke cut. Finally, a touch of design is needed. The obsidian print side panel and overall modern aesthetic makes the OM4 the signature of this collection.
