Billabong Throw On LB Black 21" Boardshort

Some garments are born following a trend, while others endure for years because they simply work. The Billabong Throw On LB Black 21" Boardshort belongs to the latter category. Inspired by classic boardshorts that have accompanied generations of surfers, it combines a clean design, a color that never goes out of style, and a 21-inch length, a measurement that is once again very present both in and out of the water.

Its completely black aesthetic conveys a sober, elegant, and very surf-inspired style. It's the perfect boardshort for those looking for a versatile garment capable of accompanying them throughout the summer: from a dawn surf session to lunch at a beach bar, a stroll along the promenade, or a seaside vacation.

At THE SURF TOWN, we only select original Billabong models because we know that when someone buys a boardshort from this brand, they're not just looking for swimwear. They're looking for a garment designed by a company that has been part of global surf history for over half a century.

Billabong, a brand born for surfing

Since 1973, Billabong has been one of the leading brands in international surfing. Its boardshorts have accompanied some of the best surfers in the world and continue to maintain the same philosophy: creating comfortable, durable garments ready to enjoy the ocean.

The Throw On LB Black precisely maintains that essence. It doesn't need large prints to attract attention. Its design opts for simplicity, demonstrating that often, less is much more.

What does it mean for it to be a 21-inch boardshort?

One of the most common questions when buying boardshorts is their length.

The 21 inches refer to the outseam length of the boardshort. In practice, this model falls approximately mid-knee, offering a classic silhouette widely used for decades in surfing.

This type of length offers several advantages:

• Greater coverage during movement.

• Authentic surfer look.

• Excellent comfort for walking, traveling, or spending all day at the beach.

• Additional protection against rubbing from the surfboard.

If you still have doubts about which length to choose, you can consult our guide How to choose boardshorts according to their inches, where we explain the differences between 17", 18", 19", 20", and 21" models.

A color that never fails

Black has always been one of the most used colors in surfing for a very simple reason: it goes with absolutely everything.

You can wear these boardshorts with white, grey, beige, green, blue, or printed t-shirts without worrying about whether they match.

In addition, it conveys a much more elegant image than other models with flashy prints, making it a much more durable purchase.

Comfort in and out of the water

One of the aspects our customers value most is that good boardshorts shouldn't just work when you're swimming.

They should also be comfortable for hours of walking on the beach, sitting on a terrace, or enjoying a trip.

The Throw On LB Black has been designed precisely with that philosophy. Its lightweight fabric promotes freedom of movement and helps with quick drying, avoiding that uncomfortable feeling of wearing wet boardshorts for too long.
