The ION Uphaul Line Core system makes hauling up the sail easy and efficient. Its lightweight design and balanced tension keep the line snug against the mast until it's needed. The classic rope construction with a durable tubular coating ensures reliable stability, while the non-slip surface offers optimal grip on every pull. The interchangeable, adjustable line attachments allow quick fitting between the boom and the mast base. Available in two sizes: size S for wave and freestyle sails, and size L for freeride and racing sails.
