The mid-layer is an essential part of gear in casual day sailing and foul-weather sailing alike. Worn over your base layer - the layer of clothing that sits next to the skin to wick away moisture from the body - the mid-layer provides serious thermal benefits (but is also highly breathable) in order to keep you warm, dry and free to move around. Gill mid-layers are constructed from high-tech fibers that don't absorb water, so they dry quickly and keep you warm. You can wear a mid-layer as a top layer in more moderate conditions, but we always recommend wearing waterproof outer layers if you're facing extreme conditions.
Sound Boatworks offers a huge variety of Gill mid-layers that are appropriate for a wide range of climates and conditions. For example, the brand provides a complete line of warmth-trapping mid-layer fleece jackets and pull-overs that can be worn as a top layer in dry conditions and as a super-warm mid-layer during foul-weather and winter sails. With stylish pill-resistant fleece that's lightweight and breathable, these Gill fleece tops can be worn during everything from intense races and offshore sails (with the appropriate outer layers) to casual shoreside events. Sound Boatworks has Gill fleece for women and men in our great selection.
For something a bit more technical that can also be used as an outer layer in mild, wet conditions, consider picking up one of Gill's windproof and waterproof jackets that blend the comfort and warmth of fleece with the technical performance of nylon. These insulated jackets have a durable, water-repellant finish plus fully taped seams to create a waterproof seal, but are lined in cozy fleece to trap in warmth. Sound Boatworks also carries Gill salopettes that bring top mid-layer performance to your more intense sails and adventures. The thermal insulation and waterproof technologies make these the perfect full-body mid-layer for intense journeys.
