Men's Flannel Pajama Set

Everything here starts with brushing. Plain or twill woven cotton passes under rollers covered in fine wire, which lift loose fiber ends clear of the surface and leave a soft nap you can feel with a thumb. Single brushed flannel is napped on the face only. Double brushed carries a nap on both sides and feels warmer against skin at the same weight.

Raised fiber traps a still layer of air, and that trapped air rather than the weight of the cloth is what keeps you warm. A 6 ounce flannel beats a 6 ounce plain weave by a wide margin. Sleepwear flannel runs 5 to 7 ounces per square yard. Plaids are almost always yarn dyed, meaning the threads are colored before weaving. The pattern shows on both faces and survives a hundred washes. Loosely spun yarn is what makes a nap possible. It is also why flannel pills, since fibers work free wherever cloth rubs cloth, at the inner thigh and under the arms first.

Compared with the Woven Pajama Set it shares a pattern and nothing else in behavior, given that one vents heat and this one holds it. The Knit Pajama Set matches it for warmth by clinging instead, and dries faster afterward. Flannel Sleep Pants sell the bottom half alone for men who run hot above the waist. Look at the Flannel Shirt in the casual shirts guide too, which is this same cloth cut for daytime.

Bedrooms under 62 degrees Fahrenheit are the natural home, along with old houses with bare floors and anyone who reads in bed before the covers go on. Drafty rentals and cabins count as well. Skip it above 65 degrees, where a napped cloth has you kicking the duvet off by 2 in the morning. Night sweating rules it out entirely, since a nap holds damp against skin long after a plain weave has dried.

Rub the surface hard with a thumb for ten seconds and see what comes away, because a flannel that sheds fiber that easily pills within a month. Check for pre-shrunk cloth on the label, as loosely spun flannel gives up 4 to 6 percent in a hot wash, more than smooth shirting does. Wash warm with the set turned inside out, then cut pills away with a fabric shaver rather than pulling them, which drags a whole yarn out of the weave.
