Outerknown Saltwater Slub Tank
Pickup currently unavailable at BSS
A Closet Staple Built for Warm Days and Heavy Rotation
The Outerknown Saltwater Slub Tank is the kind of piece you reach for without thinking. Built from a fine slub jersey knit in Regenerative Organic Certified® cotton, it delivers a lightweight, breathable feel that makes it the obvious choice for warm summer days on the water or anywhere the heat calls for something effortless.
Fine Slub Jersey Construction
Slub jersey is woven with intentional yarn irregularities that create a subtle, natural texture across the fabric surface. On the Saltwater Slub Tank, this construction does two things: it adds the right amount of sheerness and airiness for standalone warm-weather wear, and it creates a surface that layers exceptionally well when temperatures drop. The fabric is soft from the first wear, without the break-in period common to heavier cottons.
Thoughtful Details, Flattering Fit
Outerknown kept the silhouette clean and intentional. The scoop neckline sits at a flattering depth without being fussy. Rib binding along the neckline and armholes provides structure and keeps the tank in place through movement. A scalloped hem at the bottom adds a modern, feminine finish that differentiates it from a basic tank and works equally well tucked or untucked.
The slim fit silhouette creates a sleek, streamlined profile that layers cleanly under a lightweight overshirt or wetsuit jacket, or stands on its own as a warm-weather top.
Regenerative Organic Certified Cotton
Outerknown sources the cotton in this tank under the Regenerative Organic Certified® standard, which goes beyond conventional organic certification. ROC® farming practices prioritize soil health, animal welfare, and improved livelihoods for farmers. The result is a premium-softness cotton that feels better than standard organic and is grown through practices designed to leave the land in better condition than they found it.
How to Wear It
- Standalone warm-weather top: The slub texture and airy construction make it the right call on hot days when less is more.
- Base layer: The slim fit and soft surface work as a first layer under flannels, zip-ups, or light jackets when the temperature drops in the evening.
- Beach-to-town transition: Pairs cleanly with boardshorts, shorts, or casual trousers for a versatile warm-weather wardrobe anchor.
