Harper J. ★★★★★ Oct 22, 2026

The sweetheart neckline is such a nice touch on a base layer, and the corespun merino feels incredibly soft against my skin. It layers perfectly under flannels without adding bulk, and I’ve already worn it three times this week.

Finally found a merino top that doesn't itch; the corespun fabric makes it silky soft against my skin all day. Stretches just enough to move with me without losing its shape after washing.

The sweetheart neckline lays flat under my crewneck sweaters without bunching up, which is a huge plus for layering. It’s surprisingly soft against my skin and washes well without pilling.
