The breathable muslin sack — airy cotton muslin that regulates temperature naturally, the boutique-favorite arms-out bag.
aden + anais built its name on muslin, and the sleeping bag is its bedtime form: multiple layers of breathable cotton muslin that trap warmth without overheating, getting softer with every wash. It's the arms-out sack for the post-swaddle stage, in the brand's signature prints. Muslin's airy weave makes it a standout for warm rooms and summer; that same airiness means cold rooms need a higher-TOG option.

How our prices work
We show the price at our recommended retailer as at our last check of that offer (2026-10-11) and the manufacturer's list price for comparison. Amazon prices come from Amazon's own product data service and are refreshed twice a day; each one shows the date and time Amazon gave it, and one older than 24 hours is replaced by “Check price”. Other retailers' prices are checked by hand and show the date of that check. Retail prices move constantly, so the price on the retailer's own page at checkout is the one that applies.

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.
