Which material makes the best pajamas?

Set 1: Polyester Nightshirt

Expert take: Polyester isn’t great if you run hot at night, says Sheila Connell, owner of Shades of Sleep in Calgary. And it’s a common misconception that bamboo is any better. “The process to make bamboo into a fibre is a long and not environmentally friendly one — and  it’s basically just rayon in the end.”

Danielle says: “The fabric barely breathed and the shirt kept bunching up around my waist. I finally just tore the damn thing off.”

Set 2: Cotton Two-Piece

Expert take: “Full-length PJs are restrictive. A thin-strapped nightgown that stops at your knees is better for sleepers who tend to move around at night.”

Danielle says: “These PJs are adorable, so I was highly invested in them working out. They did, sorta: The cotton’s comfy, but I kept fussing with the mid-length sleeves.”

Set 3: Modal Short Set

Expert take: “Even though cotton is a great natural fibre to sleep in, Modal, a relatively new fibre made from beech trees, is extremely soft and 50 percent more breathable.”

Danielle says: “I was skeptical about the shortie-shorts, but the whole outfit is made of some light, cool magic that actually let me forget I don’t have AC. The best sleep of all.”
