Buttery soft beyond belief, always-flattering Foundation fabric looks good solo or layered, dressed up or down, season after season. This tank from Prana lives up to its Foundation reputation. It has enough stretch to wear through all your activities, but with a ridiculously soft and drapey feel, you may be tempted to sleep in the Foundation 365 Tank for women too. Don't worry, we won't tell. It features a sleeveless scoop neck tank with racerback and center back seam details. It's standard fit, made of eco-friendly 95% TENCEL™ Modal | 5% Elastane.
