Quick Answer
Choose the Campus Rib Tank for a slim, close-to-body base layer that disappears under open shirts and jackets, and pick the Cotton Cashmere Polo when you want a soft, breathable layer that works on its own or under a blazer.
Fit Differences That Matter
The Campus Rib Tank's slim, close-to-the-body fit makes it a true base layer. It won't add bulk, so it layers cleanly under unbuttoned shirts, lightweight jackets, or even a knit cardigan. The scoop neckline and straight hem keep the silhouette simple and intentional.
The Cotton Cashmere Polo uses a classic fit, which gives you a bit more room through the body. That extra ease makes it comfortable on its own, but it also means it can feel bulky under a slim jacket. If you plan to layer it, size down or choose a more relaxed outer layer.
Fabric and Seasonality
The Campus Rib Tank is 98% cotton and 2% spandex. The spandex adds stretch that helps the tank hold its shape and move with you. It's a warm-weather staple, but it also works as a year-round base layer under flannel or overshirts when temperatures drop.
The Cotton Cashmere Polo blends 90% cotton with 10% cashmere. That cashmere gives it a noticeably softer hand-feel and a touch of warmth, while the cotton keeps it breathable. It's ideal for transitional weather—think early fall or a cool spring evening—where you want a layer that insulates without overheating.
Decision Rules
- Layering under an open shirt or jacket: Choose the Campus Rib Tank. Its slim fit and stretch keep it invisible under layers, and the scoop neckline works with both button-downs and overshirts. If you want zero bulk, the tank is your pick.
- Wearing a single layer with a blazer or cardigan: Choose the Cotton Cashmere Polo. The classic fit and soft fabric give you a refined look that doesn't need a shirt underneath, and the collar adds structure. For a standalone layer that still feels polished, the polo wins.
- Warm weather vs transitional weather: Pick the tank for hot days or as a breathable base. Pick the polo when temperatures fluctuate and you need a touch of warmth without overheating. Consider your climate and how many layers you plan to wear.
