I picked up this CatWarm V-Neck Thermal Long Sleeve Top for layering on chilly days and it has become a staple. The CatSoft fabric is genuinely featherlight with ultra-soft fine fibers, so it feels barely there under a sweater. The mandarin collar, structured shoulders, and gently fitted waist give it a sleek, modern silhouette that looks tidy on its own too. It works well for both city errands and weekend walks. Only reason for four stars: it is thin, so I would not rely on it alone in real cold. Still, very comfortable and flattering.
