My Favorite Prime Day Swim Trunk Deals
Wellen
Performance Lined Swim Trunks
Any swim trunk worth its salt, has to nail the quick-drying outer layer and manage to make a comfortable inner lining to hold your valuable assets in place, the Wellen trunks deliver on both promises.
Fair Harbor
Ozone Board Short
An 8-inch inseam and a breathable compression liner; what more could you want from a board short?
Champion
Swim Trunks with Compression Liner
Champion traded the traditional mesh liner for this compression option, which essentially means these trunks can pull double-duty at the pool or for a quick bodega run around the block.
Speedo
Guard Swimsuit Trunk Volley
Speedo’s is much more than their iconic swim briefs, they also happen to make killer swim trunks as well.
Champion
Swim Trunks with Mesh Liner 7″
When you think of Champion, the reverse weave sweats are top of mind, but between you and me, the swim trunks are also notably affordable and fantastic.
Quicksilver
Comfort Liner Swim Trunks
Some swim trunks try to dabble in the shorts space, dipping their proverbial toe into casual wear pool, but Quiksilver has one mission, and that’s to keep you comfortable in the water, and they knock it out every time.
Calvin Klein
Lightweight Swim Trunk
When people ask me about “My Calvins,” I will casually point them towards these lightweight swim trunks.
Reebok
Swim Trunks with Compression Liner 9″
Reebok is rebuking the 5-inch inseam debate, and in the words of Migos going, “Big on Big”.
Speedo

Four-way stretch, a comfortable liner, back pockets, and a drawstring. It’s the platonic ideal of a swim trunk in a striking neon yellow.
Amazon Essentials
Swim Trunks with Mesh Lining

Buy these for the pool, catch yourself wearing them with zero bodies of water in sight.
