Smartwool
A cotton-and-merino crew for a casual wardrobe, with a standard cut that separates it from Smartwool’s slim active tees.

Smartwool
This slim merino tee uses a recycled-nylon core and flatlock seams, making it an active-layer alternative to the brand’s cotton-blend Perfect Crew.

Smartwool
The Classic All-Season crew is a 150 g/m² long-sleeve base layer, combining merino with recycled nylon rather than using a thick all-wool knit.

Icebreaker
Central Classic combines wool and cotton in an everyday crew. Its casual role makes it a different choice from Icebreaker’s technical base-layer tops.

Icebreaker
The Anatomica Tank removes sleeves entirely, making neckline and armhole coverage the main decisions when choosing it as an undershirt.

Woolly
This women’s crew is listed with 95% merino rather than the men’s tee’s 100%. The crew neckline gives it a different outline from Woolly’s V-neck options.

Woolly
A 95%-merino long sleeve that extends the everyday crew format into cooler mornings or layered outfits without adding a collar.

Woolx
Mia is Woolx’s regular-fit V-neck, using 150 g/m² DuraLite with nylon and spandex in the fabric. Raglan sleeves distinguish its shoulder line from a set-in casual tee.

Woolx
Junie is the loose-fit alternative to Woolx’s Mia. Both current models use the same stated 150 g/m² blend, leaving silhouette as the clearest selection difference.

Icebreaker
Sphere III combines 40% merino with 60% TENCEL lyocell, plus a drop-tail hem and side splits for a different shape from a plain all-wool crew.

Icebreaker
A women’s Sphere III short sleeve with the lyocell-rich Cool-Lite blend, offered here in black and heather color selections.

IBEX
The GOAT crew uses 150 g/m² merino-nylon fabric with offset shoulder seams, positioning it as a light blend alternative to the all-wool Naturalist.
Nylon, elastane, lyocell and cotton should not be treated as interchangeable additions. Start with the exact percentages and the maker’s construction description. A nylon-core yarn and a conventional mixed-fiber fabric can carry similar percentages while being built differently.
Then compare the garments rather than ranking them by wool content. Look at the fit, intended use and published fabric weight. A higher wool percentage does not by itself prove that one shirt has better stretch, durability or drying performance than another.
If your interest is a particular companion fiber, follow the relevant explanation before narrowing the shortlist. Our nylon guide addresses yarn construction, while the lyocell guide explains what to look for in those blends. Match care instructions to the finished garment as well; a blend is not automatic permission to use your ordinary washing and drying routine.

No. The word can appear in a blend’s name without establishing a majority percentage. Read the full composition for the selected model and variant before buying.
