This is the PERFECT year round tank. I am so obsessed that I kept one in EVERY color! they are the perfect silky fabric that still smooths everything out, they keep you snatched without keeping you from being able to breathe- if you know what I mean. Soft enough to sleep in, wear on it's own, layer, wear as an under-tank. They are seamless and incredible. Do NOT sleep on these.
