A super light down duvet is a perfect cover when we sleep with air conditioners on. It gives you the right warmth you need without the feel of weight. All super light duvets we recommend are proudly made in Canada with the finest white Goose or duck down. Specially treated to maintain extra fill power for greater luxury. Ozone treated (nature’s way of cleaning). Hypo-allergenic with Ultra-Fresh anti-microbial treatment.
