I really need cooling sheets to sleep comfortably. I bought 2 sets of these sheets after reading reviews in multiple places. I was disappointed, to say the least. Build quality is top notch, but these ARE NOT cooling. They are are cool for about 10 seconds then become neutral. They breath well, but this doesn’t matter the second you put a blanket over them. Bamboo starts cool, stays cool, and breathes just as well. Due to poor return policy, I won’t ever buy a Bedgear product again.
