Cooling Sheets Set Cal King Size - Viscose from Bamboo Cooling 4PC

In this review the Cooling Sheets Set Cal King Size is recommended for people who sleep hot and want a soft, breathable bed linen that actually feels cooler through the night. The single biggest reason to consider this set is its cooling performance: made from viscose derived from bamboo with a breathable weave, the sheets wick moisture and reduce humidity so sleepers report a noticeably cooler surface. The set comes as a complete 4PC Cal King pack and aims to deliver luxury softness while addressing overheating without heavy synthetic finishes.

Key Features

• Cooling & breathable: The viscose derived from bamboo fabric is designed to be about 3 degrees cooler than cotton and improve airflow with micro-gaps in the weave.
• Moisture wicking: The weave increases moisture absorption and wicking to reduce bed humidity by up to 50%, helping keep temperature regulated through the night.
• Ultra soft construction: A sateen weave gives a buttery, silky surface that glides on skin and becomes softer after washing for ongoing comfort.
• Deep pocket fit: The fitted sheet has a 16 in deep pocket that accommodates most mattresses and stays in place without frequent adjustment.
• Complete 4PC set: Includes 1 fitted sheet, 1 flat sheet and 2 envelope-style pillowcases with reinforced seams for durability and easy care.
• Lifetime guarantee: Backed by a risk-free Lifetime Guarantee against material and craftsmanship defects for long-term confidence.

Who It's For

The set is best for hot sleepers, people experiencing night sweats or menopause-related hot flashes, and those who want a soft, breathable sheet that performs in warm weather. Couples who share a bed and want reduced humidity and improved temperature regulation will appreciate the cooling properties and full Cal King sizing.

It may be less well suited to shoppers who need an ultra-thick mattress solution beyond 16 in pockets, or those who prefer crisp percale textures instead of a sateen, silky finish. Shoppers seeking heavily treated performance finishes should also look elsewhere, since these sheets focus on natural viscose comfort and breathability.

Pros & Cons

Cons
