The RX Chalk by TOKYO Powder.
Especially on very smooth rock with very little friction or on tricks in the hall, the RX Chalk offers incredible friction. This can be reinforced in connection with BOOST as a base layer.
Due to the high effectiveness of the RX formula, you need very little chalk to get the best grip. The pack lasts significantly longer than other chalks.
Miho Nonaka (winner of the Overall Bouldering World Cup 2018), Rei Sugimoto (third of the Overall Bouldering World Cup 2018) and Futaba Ito (Asian bouldering champion 2018) have been using this chalk in competition and are enthusiastic about the friction properties on tricks! This chalk shows its full strength especially at slightly higher temperatures and higher humidity!
It all starts with the best raw ingredients – the Magnesium Carbonate. The misconception is that all Magnesium Carbonate are produced from mining and magnesite. Here at Tokyo Powder, we work closely with the Japanese salt industry who refine the Magnesium Carbonate as a by-product of the other salts from seawater. This also greatly reduces the environmental impact that is commonly caused by mining. It also helps to keep our chalk Calcium Carbonate free – which is a bad component for friction usually found in chalk that is derived from magnesite mining.
