Frequently asked questions
Why muslin?
The open weave breathes exceptionally — warmth without the overheating risk denser fabrics carry. Ideal for warm nurseries and summer; softens beautifully over time.
aden + anais vs Kyte?
Kyte's bamboo is silkier and comes in strict TOG tiers; a+a muslin is airier and more natural-feeling. Hot sleeper wanting soft: Kyte. Breathability + prints: a+a.
Cold rooms?
Muslin's airiness means chilly rooms want a higher-TOG bag (Woolino, a winter Kyte) or a layer underneath.
Durable?
Muslin gets softer, not weaker, with washing — a multi-kid heirloom fabric.
