The Cascade range might look totally identical to the Yotei range, but don't be fooled, despite a similar visual, the cuts and construction are totally different. If the Yotei has a loose fit for more versatility in use, the Cascade is fitted, with a close fit, making it clear that it is a pure underwear for men. That said, nothing prevents you from wearing it alone if the conditions allow it, the cut is simply thinner and inevitably less diverting.As for the technical aspects, Mons Royale proposes on M's Cascade LS, a composition of 81% Merino wool, 12% Nylon and 7% Elastane for more elasticity and a faster drying. The weight of wool has the advantage of offering a great versatility in use. It can be worn in winter for skiing as well as in mid-season or summer when it is cool. A very nice technical underwear with a very effective antibacterial wool design.
