Gill i4 Fleece Jacket — Midweight, Breathable Layer for Boating

Whether you’re facing bright sun, a chilly breeze or anything in between, staying comfortable on the water starts with the right clothing. Gill’s i4 Fleece Jacket is presented as a true midweight midlayer: lighter and less bulky than traditional fleeces while still providing reliable insulation and performance for boating and outdoor activities.

Constructed from polyester velour fleece, the i4 is designed to deliver warmth without excessive weight. According to the manufacturer, the velour fleece structure traps air for insulation while remaining thin and flexible, so it layers easily under a shell or over a base layer. That balance—thermal protection with reduced bulk—makes the jacket well suited as a midlayer for sailing, powerboating or general shore-side use when conditions are variable.

Breathability and moisture management are key features highlighted by Gill. The fabric allows moisture vapor to pass through the insulating fleece to the outside with minimal resistance, helping to keep the wearer dry and comfortable during activity. Quick-drying properties reduce the time the garment stays damp after exposure to spray or perspiration, and the overall construction is intended to support active use on the water where changing conditions demand garments that move moisture away from the body.

Practical design touches enhance the jacket’s usability. Easy-grab zipper pulls make opening and closing the jacket straightforward when you’re dealing with cold fingers or while wearing gloves. Deep, mesh-lined hand pockets offer secure storage and airflow, and a dedicated chest pocket provides a safe place for small electronic gadgets or essentials you want close at hand. These utility features reinforce the i4’s role as a functional midlayer that works as part of a layered system on deck.

The i4 Fleece Jacket is available in black in both men’s and women’s cuts. The manufacturer’s suggested retail price is $95. For boaters looking for a versatile midweight fleece that minimizes bulk while delivering dependable warmth and breathability, the i4 offers a straightforward, performance-oriented option.

Care and fit considerations: as with most polyester fleece garments, the i4 is intended to be easy to maintain and to retain insulating properties after washing and drying under the recommended conditions. Because it is a midlayer rather than a heavy outer layer, it pairs well with waterproof shells or windproof layers for full protection when conditions deteriorate. Choosing the right size to allow comfortable layering—snug enough to trap warm air but not so tight that movement is restricted—will maximize the jacket’s effectiveness on the water.
