How to Care for Your Boardshorts

We’ve spent a lot of time ensuring the things you get from us are built to last. But, if you show them the right care, they’ll last even longer – and stay out of the landfill. 

Read on for our suggestions on how to care for your boardshorts.

Less Laundering. Less Impact. 
When you wash your boardshorts – especially those with polyester construction – they ‘shed’ microfiber plastics that often end up in our oceans. Whenever possible, we suggest spot-treating and hang-drying our garments. This ultimately saves water, is easier on your gear extending longevity and reduces microfiber shedding.

Hand Wash. 
Washing machines can be pretty brutal on boardshorts over time. Aside from shedding microfiber plastic, they can wreak havoc on the seams, the water-repellency and the longevity of the short. Whenever possible, wash by hand with fresh water and gentle soap. If you absolutely have to wash them in a machine, we suggest a side-load washer without a center agitator as this will be easier on your gear and help extend its longevity.

Hang Dry. 
Never put your boardshorts in the dryer. It’s hot in there. Really hot. This is especially true with our Weld Boardshort, but applies to the rest of our line. Always, always, always hang them on your backyard fence or a line to air dry.

If you're in the following locations shop through the link below:


bluesign® is the internationally recognized sustainability standard for manufacturing. In order for the fabric in this garment and the factory used to be awarded this certification, it had to pass stringent requirements around resource use, occupational health and safety of the workers making the garment, water and air emissions, and consumer safety regarding chemicals used in the manufacturing process.

The red burgee flag is much more than a brand emblem – it’s a symbol of the pride we take in the gear we make. We stand behind our equipment, so if you’re not satisfied with your gear after receiving it, or if it’s not performing to your requirements, contact our team here for a potential repair, replacement or refund.

Return Policy

Wetsuit Warranty

Use the chart below to determine your size. If one of your measurements is on the borderline between two sizes, order the smaller size for a tighter fit or the larger size for a looser fit.

Measure around the narrowest part (typically the small of your back and where your body bends side to side).

Measure around the fullest part of your hips.
