Most shorts are polyester or nylon. These are merino. Here is what that gets you.

100% Australian Merino wool in a tight plain weave. No polyester, nylon or elastane in the fabric.

Polyester sheds microplastic fibres every wash. Merino does not. And it barely needs washing, because it is naturally odour resistant, so you can just air it out between wears.

Many shorts are treated with a water-repellent finish called DWR. These are not. The fabric is just merino, so there is nothing on it to wear off against your skin or wash into the water.
We would rather you know before you buy than send them back.

I was working on boats in the Whitsundays, Australia and I could not find a good pair of natural fibre shorts I could also swim in.
It annoyed me for two or three years before I built my own natural fibre brand MARINE|O.
The original Merino Walkshort came first and has sold 140+ pairs. The Merino Wool Walkshort V2 adds a back pocket, front pockets and a crotch gusset, at no extra cost.

100% Australian Merino wool, a plain weave made with Woolmark’s OPTIM™ technology. The fabric contains no polyester, nylon or elastane.
Not if you look after them. Wash cold on a gentle cycle with a wool-safe detergent, hang them to dry and skip the tumble dryer, which is what shrinks wool.
Yes. They are designed for multi day hikes and dry quick after swimming. Rinse them with fresh water after saltwater or chlorine and hang them to dry.
Quickly. Although they are merino, they dry fast after swimming or washing and are made for life around the water.
No. There is no DWR or chemical coating finish.
No. Merino is a natural fibre, so there is no plastic to shed in the wash.
You barely need to. Merino is naturally odour resistant, so most of the time you can air them out between wears. After a swim or a hot day, rinse them with fresh water and hang them to dry. For a full wash, use a cold, gentle cycle with a wool-safe detergent. No bleach or fabric softener.
No. Merino regulates temperature and lets air circulate, so they are comfortable in hot weather.
It is best to use the size guide and measure your waist where you wear your shorts.
The waistband is adjustable, so the fit is forgiving, but if you are between sizes we recommend sizing up.
No. It is a 100% Merino wool plain weave with no elastane, so there is no stretch like synthetic boardshorts. The natural fibres soften and relax slightly with wear, but the shorts keep their shape.
An adjustable buckle waistband with a grosgrain belt, so you can set the fit yourself.
5 actually. The Walkshort V2 has a back pocket, 2 side pockets and 2 zip pockets. Room for phone, keys and a wallet.
The outseam is 19 inches and the shorts sit just above the knee.
It is a dedicated gusset panel in the crotch that spreads the load across the seam instead of one spot, so you get more room to move and less strain on the stitching.
They are designed in Australia and made in China, because that is where the specialised OPTIM™ Merino fabric and factory expertise are. After more than a year of searching we could not find another factory able to make this fabric to the same standard. The merino itself is Australian superfine merino.
