Size guide
Measure your body and find the band you fall into. Between two sizes, we suggest sizing up, because sleepwear is more comfortable a little looser.
| Your measurement | S | M | L | XL | XXL | XXXL |
|---|---|---|---|---|---|---|
| Bust | 30–33 | 33.5–36 | 36.5–39 | 39.5–42 | 42.5–45 | 45.5–51 |
| Upper arm | 11–12 | 12.5–13 | 13.5–14 | 14.5–15 | 15.5–16 | 16.5–17 |
| US dress size | 4-6 | 8-10 | 12-14 | 16-18 | 20-22 | 24-26 |
| UK / AU | 8-10 | 12-14 | 16-18 | 20-22 | 24-26 | 28-30 |
| EU | 34-36 | 38-40 | 42-44 | 46-48 | 50-52 | 54-56 |
Body measurements, in inches. Dress and international sizes are size labels, so they do not change with the unit switch.
Garment laid flat and measured across. Not body measurements. Compare these with a garment you already own that fits you well.

The 3 AM test: cotton or NightCool?
Same sweat. Different night.
| NightCool | Cotton | |
|---|---|---|
| Sweat on your skin | Pulled off you. Dry fast. | Soaks in and stays. |
| Odor | Bact-Out finish, so the fabric stays fresher | Nothing in it to help |
| After the wash | Holds its shape, no pilling | Pills with wear |
| By 3 AM | Dry | Damp |
Try it for 30 nights. Not cooler? Send it back. How the trial works
