About this product
Real mulberry silk, and machine washable.
19 momme natural mulberry silk with couture-grade french seams, in black or blue, supplied in a silk gift pouch. One of only two silk garments we sell for men.
These are actually silk. Along with the mulberry lounge robe, they are the only silk menswear on this site: everything else in the men's range is a satin weave in polyester.
19 momme natural mulberry silk, which is a garment weight rather than a bedding weight, made with couture-grade french seams so nothing raw sits against the skin.
They are machine washable, which is unusual for silk and is the result of the density at 19 momme plus the seam construction. Cold, gentle, in a mesh bag.
Black or blue. They arrive in a silk gift pouch, which is why they are bought as a present as often as for the buyer.
Silk is worth paying for here for the same reason it is worth paying for on a pillowcase: it moves moisture and it does not cling, in both summer and winter.
Silk underwear has a reputation as an indulgence, and the practical case for it is better than that. Silk moves moisture away rather than holding it, and it does not cling when it is warm, which is the reason it is worn in hot climates as much as cold ones.
19 momme is the weight that makes them wearable rather than delicate. Lighter silk in this application wears through at the seam; heavier loses the drape and the point.
French seams are the construction detail that matters. The seam allowance is folded inside itself, so there is no raw edge and no overlocking against the skin. It is also what lets them survive a machine cycle.
That machine washability is the genuine surprise here. Most silk garments want hand washing. Cold water, a gentle cycle, a mesh bag and an enzyme-free detergent, and these behave like ordinary underwear.
They come in a silk pouch, which is a gift decision rather than a packaging one and is worth knowing if you are buying them for yourself.
Still deciding?
Not sure yet? That is fine.
You can change your mind. You have 15 days from purchase on any unused item in its original packaging. That sits on top of the 14 day right to cancel that Irish law gives you on anything bought online. On a cancellation you pay only the direct cost of sending the goods back.
If it turns up faulty, damaged or not as described, that is on us. Under the Consumer Rights Act 2022 you are entitled to a repair or a replacement first, and to a price reduction or your money back where that does not put things right. We pay the return postage and nothing on this page limits any of it. Read the detail on our refunds and returns page, or ask us anything before you order.

The complete guide
Why silk underwear is not only an indulgence
3 min readFlair Silk Company
The practical argument
Silk moves moisture away from the skin rather than holding it, and it does not cling when it is warm. That is why silk underwear is worn in hot climates as well as cold ones, and it is a property of the fibre rather than a claim about comfort.
19 momme is the wearable weight
Momme is a weight. Lighter silk than this wears through at the seam in an application that gets this much movement; heavier loses the drape. 19 is where garments in this category sit for a reason.
French seams are why they last
The seam allowance is folded inside itself, so there is no raw edge and no overlocking rubbing against skin. It is also the reason these survive a washing machine when most silk garments do not.
Yes, machine washable
Cold water, gentle cycle, mesh bag, a detergent with no enzymes, no bleach, and air dry them. Not the dryer: heat is what kills silk and elastic alike.
Silk here, satin elsewhere
Most of the men's range on this site is a polyester satin, which is a weave rather than a fibre. These boxers and the mulberry lounge robe are the two genuinely silk items. Each page says which it is.
Tell us what you want it to do and how you do laundry, and we will tell you whether the silk or the satin is the better spend. Free delivery across Ireland on orders over €60.
