Berkshire LifeEcoSoft Queen Blanket - Gray

Can you dry it in the dryer?

Has aybody washed and dried this blanket? It says to tumble dry no heat. Will heat ruin it?

What is the descriptive '400 GSM' jargon?

i bought one from costco, it wouldn't stop shedding. I follow the instruction. is it just me or people have the same issue
