Best Sleepwear for light packers

I like microfiber bottoms and usually a cami. They are soft, comfy and packable.

I like a PJ that is stretchy knit and is capris length with short sleeves. i have micro fiber robe for fire drills, remote bathrooms and other uses.

I generally take an oversize t-shirt that is long enough to cover my butt. If I choose not to wear it, I at least have it on the bed so I could grab it quickly. (I'll save the story of how I locked myself out into the hallway of a Chinese hotel, wearing only the t-shirt, for another time.)

I have cotton knit Long &/or capri pjs (Hue brand-Macy's) & a tee from Wal-Mart. When you have to use a bath down the hall, I feel covered enough to trip out to it. Never a robe. If it is too hot in the room, I can always just use the tee.

Athletic, longer shorts and a t-shirt. I don't like long-sleeved shirts or pants when I sleep.

Duofold type t-shirt tops (they wash and dry overnight, are intended to breathe for hot weather) and lightweight cotton capri bottoms (tested for wash/dry overnight capabilities). Assuming you're not in the third world, you can probably ask for an extra blanket if it's cold.

"Assuming you're not in the third world, you can probably ask for an extra blanket if it's cold".
I am sorry but what does that mean? That it's always hot in third world countries so an extra blanket is not required or that they won't have one should you ask? Forgive me but I just can't see the connection.
Thanks.

Sleep naked. Just stay out of London! Go to Cape d'Agde.

Thanks to all for your helpful suggestions.

I have some silk knit nightgowns and silk broadcloth pjs from WinterSilks that have worked well for me. They are really lightweight and compress amazingly for packing. I also usually take 1-2 silk undershirts, which can be layered under nightwear as well as daywear. Last time I checked Wintersilks had pjs in holiday colors plus an assortment of unisex nightshirts/gowns on sale.

Ditto Kathleen on the silks. In summer I bring a silk cami and silk boxer shorts - both pack down really really tiny and extremely light. In winter, I bring silk long-johns. Again - very lightweight and compacts into a small amount of space.

I got my silk boxers from Dreamsack:

They also have silk drawstring pants that could work as pj bottoms, along with an assortment of silk nightwear.

I stay with the "pack light" principle when it comes to sleeping wear. I sleep in light-weight cotton knit pants and a t-shirt. If I feel cold, I put on the cotton turtle-neck shirt. These are clothes that can be worn outside, too, and don't look like pjs.

I just take a tshirt that's comfy, and also a pair of athletic pants, capri length, to put on if I have to leave during a fire. They are comfy enough for lounging in my room, but decent enough that I can go down the hall for ice. (Well, the ice would be in an American hotel, not European!) No robes, no pj-looking pants.

O.K. So I'm going to show my age here(62) I love the zip up "house dresses" that are usually made of light seersucker material. I get them at Wal-Mart in the pajama department. They cost around $10.00. They are good lounging wear after a long day of sightseeing, could pass muster if you had to walk down the hall to the bathroom, and they don't weigh anything at all. I also take a pair lightweight slippers. After a couple of days, I wash the gown out in the sink and hang it to dry and its fresh to wear in the evening again.

I always maintain that even though sleeping au natural, if in the extremely unlikely event of a fire, bystanders will just remark on my fabulous jewellery and painted toenails. I hope. I actually take an overshirt to pull on when I get up.

Silk long underwear. Wearing it at night prevents a body from being cold. When folded it occupies a very small space in a travel bag. If you think the air will be very cold in your room at night, I recommend the Duo Fold long underwear : the inside is cotton, the outside is a blend of cotton and wool. The Campmor catalog has it for a discounted price.
