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
Chest	38–40	40.5–42	42.5–44	44.5–46	46.5–48	48.5–50

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.

Wake up cool and dry. The Cool-jams Men's NightCool Crew Neck T-Shirt is a men's cooling sleep shirt built for hot sleepers and for nights when you run warm. This men's moisture-wicking sleep shirt is made from our proprietary Kottinu fabric, which pulls perspiration off your skin and dries fast, so you stay comfortable all night.

Part of the Cool-jams NightCool collection of cooling sleepwear for men.

More about the Crew Neck T-Shirt

The Cool-jams NightCool Crew Neck T-Shirt is a cooling sleep t-shirt for men with night sweats. The Kottinu knit pulls perspiration off the skin as it forms and dries fast, so the shirt does not stay wet against your back, and an odor-control finish helps the fabric stay fresher between washes. It is cut as a standard crew neck tee, relaxed through the body and shoulder, which is why customers wear it for travel and the gym as well as for sleep. In Navy and Black, in sizes M to 2X.

Can I wear this outside bed?

Yes. It is cut like a normal crew neck tee, and the fabric performs the same way in a gym or on a plane as it does in bed.

Is it good for night sweats?

That is what it was built for. Kottinu wicks moisture off the skin and dries fast, which is the property that matters when you sweat in your sleep.

What bottoms match it?

The NightCool Pants and the NightCool Boxer Shorts in the men's range.

Why you'll love it

Short-sleeve crew neck sleep shirt for comfortable all-night wear
Kottinu moisture-wicking fabric that wicks perspiration and dries quickly, engineered for hot sleepers and night sweats
Soft, cotton-like feel that resists pilling, holds its shape, and machine washes easily
Bact-Out finish helps the fabric stay fresher between washes
Mix-and-match with any NightCool bottom for a complete sleep system

What is Kottinu?

Kottinu, a technical synthetic (engineered polyester microfiber) made for firefighter base layers and medical scrubs, now crafted for hot sleepers and night sweats needing moisture-wicking and cooling pajamas. Soft and smooth with a cotton-like feel, it pulls sweat off your skin, dries fast, carrying body heat away with it.

A Bact-Out finish helps the fabric resist odor, so it stays fresher between washes. Kottinu resists pilling, holds its shape, and machine washes easily.

How to care for Kottinu

Machine wash cold or warm with like colors, gentle cycle
Skip fabric softener and dryer sheets, they coat the microfibers and can reduce wicking
Tumble dry low or hang to dry, Kottinu dries fast
No bleach
Holds its shape and resists pilling wash after wash

Men's NightCool Crew Neck T-Shirt
Rated 5 out of 5 stars
Men's tee
This is a repeat purchase and I bought 2 as soon as you got these back in stock. I had almost worn out my other one. I have to buy the men's because the women's products are all too small.

It is a very comfortable sleep shirt that does not bind and keeps me comfortable. Not too hot and not too cold.
