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

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

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

I purchased my first pair of these thermal tops wondering what the quality would be like given that the price was so reasonable. I have to say that I have been delighted with them. They are lightweight but so warm and comfortable and they wash and dry beautifully. They are long in the body but not excessively so. One reviewer mentions sleeves widening at the wrists but I would contradict this by saying they fit perfectly. True to size, I have gone on to purchase more this winter and they are my go-to base layer, chosen in preference to other more expensive base layers in my wardrobe.

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

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.

This is the second pair of these t-shirts I've bought. The first pair were so good I immediately ordered some more. They seemed too lightweight to be 'thermal' when I opened the pack, but the inside of the fabric is lovely and fleecy and it's truly thermal without making the item bulky, as many thermal clothes are. They are light enough to wear a jumper over the top without feeling packed with clothes that restrict movement. Also, the neckline is nice and high, unlike thermal t-shirts I've had in the past. What's the point of wearing something 'thermal' when half your chest isn't even covered! And, the sleeves are really good and long, reaching right over your wrists if you pull them fully down, so really snuggly if you fit them into gloves. Can't fault them, perfect.

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.
