SIMIYAThermal Tops Womens Round Neck Soft Base Layers Long Sleeve Top Women Thermal Underwear Shirt Warm Wicking

Tested these on a recent trip to Iceland. Just wore these tops under a jumper. Pleasantly surprised, they are good quality, soft, warm and comfortable. Small was not tight, I’m a 10-12. Long in the body. Washed and tumble dried well. So pleased I am going to order more.

The tops are lightweight so great to wear under clothes and are really comfortable. I went for a size bigger and they fit perfectly. Not yet been the washing machine, so I hope they wash well

Warm and long enough that you're not tucking it in all the time. Washes well.

Good fit, feel warm but it is way too long to tuck in

If you’re looking for warmth, long sleeves and long body length, not too tight under-layer for cold weather these are perfect. Soft and cosy and really comfortable. I’m a UK 12-14 and ordered a large as I don’t like tight tops and they were perfect and stay tucked in!

Lovely warm vest nice & soft , a little long in the arms & body

I am size 14 and found the L rather tight, especially the arms which are extremely slim. They don't feel particularly soft so not sure they would give feeling of warmth on a cold day.

Warm, well fitting, a flattering cut and looks to be good quality, with no loose seams or defects.

This black thermal is perfect! I bought it to wear under my scrubs at work and it keeps me warm. It’s very comfortable and I will probably buy more just to have because it’s that great.

I work outside at night and warmth without bulk is important. These are very warm, soft and comfortable. They do run BIG! my normal size I could wear as a dress. Definitely size down they are super stretchy too so don’t be afraid to go smaller than you think

I normally don’t write product reviews but these are my new favorite shirts for the winter! Not only are they extremely soft on the inside and outside and super comfortable, but they’re also really warm and great for layering. I sized up for comfort but they’re really stretchy

It's nice and warm, but it's SUPER long if you're petite. I'm 5'1 and 115 lbs, and I'm usually a size S, but I sized down to an XS. It looks like a dress on me!

Not as warm as I wanted.
