For maximum comfort during downtime at home, opt for this long-sleeve tee from Derek Rose. Its ultra-cozy fabric has to be touched to be truly appreciated. An undeniably soft blend of micro modal (woven from sustainably forested beech trees) and elastane come together to create this garment that can easily take you from lounging on the couch to a yoga class. The thermostatic qualities of the fabric respond to temperature, offering more insulation when it's cooler. Whether wearing it to bed or on a long-haul flight, you'll be glad you chose this style.
