The Mack Weldon Men's Swim Short is a premium performance swimwear option designed for both water and everyday wear. Mack Weldon is known for engineering men's basics with superior fit, comfort, and durability, and these swim shorts reflect that commitment.
Constructed from a quick-drying, stretch-woven fabric blend, these shorts offer freedom of movement whether you're in the water or on the move. The 4-way stretch construction allows natural movement in every direction, while the fast-drying material ensures you stay comfortable as you transition from swimming to other activities. A secure waistband with an interior drawstring provides an adjustable, personalized fit across a range of sizes.
Functional pockets — typically including side hand pockets and a rear zip pocket — keep essentials secure. The shorts feature a versatile, athletic silhouette with a mid-thigh inseam length appropriate for a variety of body types and activities. Available in multiple colorways and in sizes ranging from S to XXL.
