The On Ultra Vest Pro is On's top-of-the-line trail vest, with a 10 L dry pack and two 500ml flasks. The official Japan price is JPY 26,400.

The Ledlenser HF4R (2026 model) is a headlamp released in mid-Sep 2026 at an official JPY 7,480. It weighs 92g with batteries, lasts 10 hours at 100 lumens, and still lights up on 3 AAA batteries if the rechargeable pack runs out.

The base is 9 items required by 3 of the races, and 7 items have numeric specs, such as a light of 80 lumens or more for at least 4 hours, at least 1 L of water, and a blanket of at least 130×200cm. I also worked through the 2kg gear rule.Trail running · Oct 15, 2026
