Sierra D3O® WP Boot



Merlin Explorer Collection

The Merlin Explorer Collection has been designed to complement the rise in accessible, do-it-all motorcycles, alongside the growing number of riders pushing themselves, exploring and creating memories. Explorer offers rugged styling, durability and protection while incorporating the signature Merlin styling using only the best materials and components, such as high performance single-layer laminated styles, Halley Stevensons® ripstop fabrics, D3O® armour and Cordura®.

Merlin Sierra D3O® Waterproof Boot

Sierra is the first Merlin boot to feature a Vibram® high grip, no slip, easy to clean vulcanised sole. In a mid-height fit, leather construction combined with durable scratch rubber, Sierra is lightweight, easy to wear, has great comfort levels and importantly high levels of durability. Further, Sierra features an innovative ratchet closure system for micro-adjustable precision fit and D3O’s shock absorbing impact protection.

Caring For Your Sierra Boots

The Sierra boots are easy to care for. After each ride, with a dry brush remove any debris, particularly around seams and sole joint. Like any sealed leather, these can be cleaned and conditioned using any one of the large selection of leather products on the market. We would always suggest testing any cleaner you purchase on an inconspicuous area of the boot first. View our full wash and care guide here: Merlin Wash & Care.
