One of the most adaptable pieces of Simsek's offerings, Lightning Thermal Base Layer Top is your non-negotiable for any fall to winter outdoor adventure. Your new companion for hiking, skiing and pretty much any chilly city cruise to keep you warm and cozy.

Just at the right thickness at midweight 240gsm, it is great for cool to chilly weather. Wear it alone or  pair with fleece or a rain jacket to adapt to changing weather conditions at any time.

Made from luxurious, buttery-soft 100% merino wool, it offers brilliant thermoregulation, breathability and odor resistance so the rest in the ski resort will become worry-free. Only 18.5 micron fine merino fibers offer ultimate itch-free comfort.

It features all-around best-in-class flatlock seams unlike many others in the market for full chafe-free design and ultimate comfort that moves with you. Shoulders also features offset seams, and this helps with backpack usage so the seams won't dig into your skin. It also prolongs the life of the product because the seams will stay intact, for longer.

The neck label is printed so you won't have to deal with an itchy label rubbing your neck.

Our cuts make this base layer extra special, sitting close to your body with slim fit for layerability and yet it doesn't completely stick to your body. We avoid the pajama-y look (not the pajama-y comfort), and finish the sleeves at your wrist, hems slightly longer around the hips, so you can even pair this with business casual look under your blazer jacket. Offered in combinable colors that go well with many jackets, indoors and outdoors.

All these come together in machine washable merino to make things easier for you.

Simsek's luxury take on how outdoor clothing should be. As promised.
