Not durable, cut is ridiculous

I used to wear climasense (2010-2014) products religiously. This 1.0 silk is already pilling after one days use, entirely inside, mostly watching TV.

The cut is absurd. The arms are big enough to fit legs, and don’t reach the wrist. And I have short T-Rex arms!

Not at all worth $65, or even $10.

Good sleeping shirt

My husband is happy to have his first thermasilk shirt. It’s light but warm and enables him to turn easily in bed (has a disability) will recommend this product.

Thomas Taggart
ticks all the boxes

Wonderful material, light but warm next to skin unlike poly. Not bulky but still slim.
