Untuckit vs COS: which sweater wins?
Both land in the mid tier — the Untuckit Cotton Crewneck Sweater at $88, the COS Merino Wool Crew Sweater at $89, just $1 apart. Here's how they stack up, head to head.
| Untuckit | COS | |
|---|---|---|
| Price | $88 | $89 |
| Material | Cotton, merino or cotton blends depending on style, mid gauge. | Merino wool, heavier gauge. |
| Fit | Clean smart-casual fit cut for layering, true to size. | Clean architectural cut, slightly boxy; size down for a trimmer fit. |
| Quality | Solid mid-tier — clean knit and finishing; fine wool styles pill over time. | Above high-street average — substantial merino, design-led finishing; consistency varies by batch. |
| Best for | Layering over shirts, smart-casual dressing, and clean everyday knitwear. | Minimal, design-led outfits and anyone wanting a heavier, architectural merino knit. |
| Care | Wash per the fibre; cotton machine-washes, merino needs a wool cycle. Lay flat to dry. | Gentle wool cycle or hand-wash and lay flat to dry. |
Untuckit's $88 cotton crewneck and COS's $89 merino crew are a dollar apart but built differently. The near-identical price buys you either a clean cotton layering knit or a heavier, design-led merino with real wool warmth.

Which should you buy?
One dollar separates these, so decide on material and look. Buy the Untuckit if you want a true-to-size cotton crew that layers cleanly over shirts and you don't need wool warmth. Pay the same for COS if you want a heavier merino knit with more heft, more warmth and a minimal architectural cut; just size down since it runs slightly boxy and expect some batch-to-batch fit variation. For wool over cotton at the same price, COS is the stronger pick.
