Turn the waistband over
A label is not
a small detail.
Polyester is a synthetic fibre. Merino wool is a natural fibre. Blends can contain both. Look at the composition, not just the word “soft” on the pack. Here is what our three-pack actually contains.
| What to check | Polyester underwear | NUMBNUTS three-pack |
|---|---|---|
| Body fabric | Synthetic polyester, sometimes blended with other fibres. | 100% merino wool body and sleeve. |
| Waistband | Composition varies. Read that part of the label too. | Natural rubber waistband. |
| What you buy | Depends on the product and pack size. Check the listing. | Three everyday boxers. One selected size. No cooling inserts. |
This is a materials comparison, not a claim that these boxers prevent harm or improve fertility. Wool care matters: follow the garment instructions.

The details matter
Before you commit.
The first thing you put on should not be the last thing you consider. That is why we started with merino and natural rubber. Three everyday pairs here. Cooling inserts in the separate bundle.
Are cooling inserts included?
No. This product contains three boxers only. If you want targeted cooling, the separate bundle includes one boxer and two reusable inserts.
