Scott’s top-end aggressive trail helmet is only available with MIPS, as the Swiss brand were early adopters of the system. The EPS extends low at the rear without clashing with the retention system and the strap attachment points are external to the liner, maximising the amount of material around the temples. This is the closest-fitting helmet on test, with very little clearance inside the liner. Despite this, and although the Stego has fewer vents than some other lids here, we never felt too hot-headed. Scott spent time developing the ventilation system using a wind tunnel and it seems to have paid off. The thin pads don’t offer quite as much comfort as some competitors’, and while the short peak is removable, it doesn’t offer any height adjustment. Weight 340g Sizing S, M, L Price $180
