Part of Casper’s latest cooling collection, the Hyperlite sheets are, as the name suggests, unbelievably lightweight. They’re made with 100 percent tencel lyocell, a durable, moisture-absorbing fiber that’s sustainably sourced from wood. What’s more, the sheets feature a grid weave that makes them about as breathable as it gets. The pattern creates an almost see-through effect that allows for more airflow throughout the night. I was skeptical that these thin sheets would feel uncomfortable and prove to be flimsy—I even did a visible double take when I initially got them out of their packaging because the texture was so different than anything I’d seen before. But, determined to give them a try, I put them on my bed before one of the first truly warm nights of the year in New York City. To my pleasant surprise, they felt soft and comfortable and kept me from overheating as I slept, even while underneath a fluffy duvet. And despite their thin, gauze-like texture, the sheets didn’t seem susceptible to rips or tears at the slightest snag thanks to the high-quality construction of the tencel lyocell grid weave. If you’re tired of waking up covered in night sweats or are in need of a lightweight set of sheets to replace your heavy-duty winter ones, Casper’s Hyperlite sheets are worth a try. They’re as close as it gets to sleeping with no sheets at all. Head to Casper to pick out your new summer bedding today.
