CATSSTAC Wool crew-neck base layer

Fabric:
* Sheep's Wool: Adds a fine, soft wool texture and a bit more warmth, making the fabric feel gentle on the skin.
* Tencel/Lyocell (Regenerated Cellulose Fiber): Improves breathability and skin-friendliness; moisture-wicking and airy, so it avoids synthetic stuffiness and feels soft and supple.
* Acrylic: Adds loft and warmth; soft, fleece-like feel that resists stiffening.
* Nylon: Increases yarn toughness and durability (abrasion and tear resistance), reducing breakage and pilling so it lasts longer.

Fabric Texture:
* Heathered/mélange effect: The creamy, multi-tonal blend looks premium—simple but sophisticated.
* Fine knit: Smooth to the touch and comfortable for direct skin contact without irritation.

Fit & Design:
1. Classic crew neck: Reinforced ribbed collar resists stretching or curling out of shape; comfortable around the neck and great for layering under outerwear.
2. Tonal embroidery on the chest: Subtle and refined, adding a distinctive detail without being flashy.
3. Slightly loose, straight-cut fit: Roomy and comfortable, not restrictive.
4. Straight cuffs sit close to the wrists to block wind; neat hem looks good tucked in or worn loose.
