Oh Buoy 2N1 Shorts: How the Built-In Liner Works

Learn how the built-in liner in Oh Buoy 2N1 shorts separates support from swim coverage, plus a simple step-by-step routine for wearing, rinsing, and packing them.
Quick answer
Treat the Oh Buoy 2N1 as two layers working together: the outer shell handles swim coverage and movement, while the built-in liner provides cooling support next to the skin. Wear it like a swim short, then rinse and dry both layers separately after use.
What the liner actually changes compared with regular shorts
Regular swim shorts are usually a single shell with a mesh or brief lining, so support and coverage are tied together. The Oh Buoy 2N1 separates those jobs: the 4-way stretch shell moves with you, and the DropTemp Cooling Hydro Liner sits underneath with the BallPark Pouch® for support. That means you can adjust the outer short for fit and coverage without losing the liner's hold.
The trade-off is a little more fabric against the skin than a bare mesh liner. If you prefer the feel of a separate compression layer, the 2N1 format gives you that in one piece; if you want the thinnest possible swim short, a single-layer short may suit you better.
When the two-layer design earns its place
The liner is most useful when you move between water and dry land without changing: swimming, then walking the beach or heading to a casual lunch. Because the shell is separate, you can rinse and dry it faster than a short with a sewn-in mesh brief, and the liner keeps its shape for the next wear.
For long pool sessions or repeated laps, expect the liner to stay wet a little longer than the quick-drying shell. That is normal for a two-layer short, and it is why the rinse-and-dry steps below matter more than they would for a single-layer pair.
How to wear and care for the Oh Buoy 2N1 liner
- Put on the liner first, then the shell: Step into the liner and settle the BallPark Pouch® before pulling the outer shell up. Common mistake: yanking both layers up together, which twists the liner and defeats the support. Check that the liner sits flat at the waist and leg openings before you head out.
- Rinse the liner and shell separately after salt or chlorine: Turn the shorts inside out, rinse the liner under cool water, then rinse the shell. Common mistake: machine-washing immediately after every swim, which wears the liner faster than a simple rinse needs to. If the liner still feels slick or stiff after rinsing, repeat the rinse before drying.
- Dry the liner fully before packing: Hang the shorts inside out with the liner exposed until both layers feel dry to the touch. Common mistake: folding them damp into a bag, which traps moisture in the liner and leaves a smell. Pack them only when the liner is dry, not just the outer shell.
Product facts
- Oh Buoy 2N1: Oh Buoy 2N1 pairs a 4-way stretch shell with an integrated BallPark Pouch® and DropTemp® Cooling Hydro Liner. The shell gives you swim-short coverage while the liner supplies the support and cooling feel, so you do not need a separate base layer.
