    • Excelente para temperaturas bajas
Size: Small Color: Black
Lo compré para visitar una montaña y funcionó a la perfección. Muy cómodo y buen material. Revisé varios artículos y todos tenían precios similares, así que muy feliz con haber elegido esta opción que tenía buenos comentarios. Utilicé esta ropa por debajo con capas adicionales de ropa por encima y dado que es ligeramente ajustada al cuerpo, no se sintió incómoda en ningún momento. ... show more

Review Image by ZodiacKing
I’m not sure what to think 🤔 about this. First off it does seem like a onesizefitsall elastic type stretchy fabric that just hugs your body like some kind of spandex or yoga pants w/ women. Which isn’t bad per-say maybe it’s just me but my reason for buying this was for warmth. To have an extra pair so that I don’t over use what I already had before buying this. Now if it’s just a cool sunny day maybe a little breeze maybe you’re near a body of water whatever. Then yeah it’s not bad it’s very breathable like almost too much. I wear extra layers to feel warm, cause it takes time for my body to warm up and I can’t retain heat. The doctor said I need more iron and fiber in my diet. Even in the summer I’m cold. I’m not going to return it, I do like that it came in my favorite color, but I wouldn’t buy this again. I’ll just have to put other layers over it when the temperature drops. But I can’t just wear this if I expect to feel warm. I do like that it feels silky and slides on me so smoothly lol I’m not used to putting on any clothes with that type of material and again good that it’s in my favorite color but I feel it’s more for show like under a checkered shirt or something. But not practical as in not warm enough to be considered a long-Jon but again as I said maybe it’s just me, no two people are the same and I’m sure to someone else it might be warmer or even maybe hot. Thanks for reading 📖 👍🏾 ... show more
