Star`s NEXT wax line is the top of its class! Its a full line containing everything you need for top-level, fluoro-free racing: liquids, blocks, powders, paraffins, and even a dirty snow spin-off line. The Durable Long Distance Block is a great option to put underneath the NEXT block of the day, or even to use on its own for aggressive conditions. Star blocks are a speedy topper for cold apply application. Apply block directly onto roto wool applicator, run along ski base for 2-3 passes, then finish with soft nylon. For each NEXT block you use, you should use a seperate roto wool applicator. This stops cross-contamination between waxes which may have different additives which may work counter-productively to each other. Make sure to label each wool with which wax it was used with! Like all NEXT products, the paraffin has Star`s ceramic technology for the best fluoro-free performance! Best pairs with NEXT bases. Comes in 28g blocks (actually 32g on a scale) in cardboard packaging for less plastic waste.
