Fall Pima Cotton Favorites: Turtlenecks & Long-Sleeve Polos
When the leaves turn and the air crisps, it’s time to transition into fall layers — and few are as versatile and stylish as our men’s Pima Cotton turtlenecks and long-sleeve polo shirts. Designed with comfort, breathability, and warmth in mind, these cotton classics are essential additions to your cold-weather wardrobe.
The Beauty of Pima Cotton for Fall
Our garments are crafted from extra-long staple Peruvian Pima Cotton, prized for its luxurious softness, remarkable durability, and thermal regulation. Hand-picked and hand-crafted in Peru, this cotton adapts to seasonal shifts — cool in summer, insulating in winter.
Men’s Pima Cotton Turtlenecks

A Lanam Shop staple, our Pima Cotton turtlenecks feature a traditional roll collar or a modern mock neck. Designed with a classic cut through the body and ample room at the neck, these shirts are:
- Exceptionally soft and non-irritating — even when layered under wool or tweed
- Naturally insulating, thanks to their jersey stitch and all-cotton composition
- Available in rich autumn hues including forest green, wine, and oatmeal

- A smart standalone option for mild weather

The Pima Cotton’s natural ability to wick moisture and distribute body heat helps you stay comfortable throughout the day, without overheating or becoming chilled.
Why Cotton Works in Cold Weather
Cotton may be known for summer wear, but high-quality Pima Cotton makes an ideal cold-season base layer. Our shirts are knit slightly thicker than traditional short-sleeve polos, creating better heat transfer balance between your skin, the cotton, and any layered outer garments.
- The jersey stitch promotes air circulation and heat diffusion
- Natural cotton fibers regulate temperature without trapping sweat
- No synthetic fibers (like polyester or spandex) to interfere with your body’s rhythm
Combined with wool or cashmere layers, our cotton shirts create two heat zones: one between your skin and shirt, and another between shirt and sweater. This dynamic layering promotes radiant warmth while keeping moisture away from the skin.
The Lanam Shop Difference
Our commitment to quality is found in every stitch. From hand-set collars to artfully
reinforced seams, our Pima Cotton garments offer luxury-level performance and timeless style.
- Non-itchy, easy-care natural fibers
- Machine washable for daily wear
- Designed for all-season versatility
Whether you’re apple picking, walking through a golden-hued park, or simply staying warm indoors, our fall-ready Pima Cotton shirts deliver comfort and polish.
