Sleep sacks

Unweighted sleep sacks with natural-fiber fabrics and filling, without added chemical flame retardants.

A wearable blanket can replace loose bedding when the size and warmth suit the child and room.  We assess any hidden fill as well as the outer fabric, favoring natural materials.  Follow the age, fit and temperature guidance; weighted sleep products are not included.

CastleWare Long-Sleeve Cotton Fleece Walker Bag — Black Forest, TOG 2.0 CastleWare Long-Sleeve Cotton Fleece Walker Bag — Black Forest, TOG 2.0 ORGANIC COTTONUSA PRODUCTION Why we recommend it: Long sleeves and a brushed cotton interior offer fuller coverage without polyester microfleece.  Fold-back ankle cuffs and a fabric-backed zipper make this a wearable alternative to a loose blanket.  Sewn in the USA with cotton sourced mainly from Texas and sometimes India.  Adjust layers for the room; a TOG rating alone cannot determine a child's comfort.

CastleWare Organic Cotton Rib-Knit Walker Sleep Bag — Natural, TOG 1.5 CastleWare Organic Cotton Rib-Knit Walker Sleep Bag — Natural, TOG 1.5 ORGANIC COTTONUSA PRODUCTION Why we recommend it: Undyed cotton rib knit makes a lighter wearable layer with foot openings and fold-back cuffs for a mobile toddler.  A fabric placket backs the bottom-opening zipper.  Made in the USA using cotton sourced mainly from Texas and sometimes India, this sleeveless design avoids polyester fleece.  Follow the size chart and check the fit at the neck. Materials: 100% organic cotton rib-knit fabric, undyed · YKK zipper and fabric placket · cotton sourced primarily from West Texas, sometimes India $65.00 View product
CastleWare Sleeveless Cotton Fleece Walker Bag — Black Forest, TOG 2.0 CastleWare Sleeveless Cotton Fleece Walker Bag — Black Forest, TOG 2.0 ORGANIC COTTONUSA PRODUCTION Why we recommend it: The cotton-fleece body offers warmth while leaving arm layers up to you.  Foot openings suit a mobile toddler, and a fabric placket separates the zipper from the skin.  CastleWare makes it in the USA with cotton sourced mainly from Texas and sometimes India, and reports no added fire-retardant treatment.  Check fit and avoid excess layering.

Disana Cotton-Lined Boiled Wool Sleeping Bag — Rose, Size 1 Disana Cotton-Lined Boiled Wool Sleeping Bag — Rose, Size 1 ORGANIC COTTONWOOL Why we recommend it: This lined design puts organic cotton next to the body and dense boiled wool on the outside, rather than polyester padding between fabric layers.  A long front zipper and protective cover simplify dressing.  The wool comes from Argentina and the sack is made in Germany; the cotton's country of origin and zipper composition are not specified.  Use its added insulation thoughtfully, with a correctly fitted neckline and suitable room layers. Materials: organic Merino boiled-wool shell · organic cotton lining · zipper and small trims (composition not specified) $119.95 View product
Disana Organic Merino Long-Sleeve Sleeping Bag — Dove Blue, Size 1 Disana Organic Merino Long-Sleeve Sleeping Bag — Dove Blue, Size 1 WOOL Why we recommend it: Long knitted sleeves distinguish this design from a standard sleeveless sack, providing arm coverage without a separate synthetic-fleece layer.  The front opens down its length with tagua-nut buttons, making changes easier than pulling a closed sack over the head.  Made in Germany from Argentine organic Merino wool.  Account for the sleeves when choosing underlayers; extra warmth is not automatically better. Materials: organic Merino wool · tagua-nut front buttons · label and sewing-thread composition not specified $69.95 View product
Disana Organic Merino Sleeveless Sleeping Bag — Dove Blue, Size 1 Disana Organic Merino Sleeveless Sleeping Bag — Dove Blue, Size 1 WOOL Why we recommend it: A simple wool knit replaces polyester fleece without adding a bulky filling layer.  Shoulder buttons open the sleeveless top for dressing, while the roomy knitted sack leaves space for the legs.  Disana specifies tagua-nut buttons and Argentine Merino wool, with production in Germany.  Choose by neck and shoulder fit, not age alone; wool still needs sensible layering to avoid overheating. Materials: organic Merino wool · tagua-nut shoulder buttons · label and sewing-thread composition not specified $59.95 View product
Reiff Cotton-Lined Merino Long-Sleeve Sleep Sack — Natural, 62/68 Reiff Cotton-Lined Merino Long-Sleeve Sleep Sack — Natural, 62/68 ORGANIC COTTONWOOL Why we recommend it: The fleece here is organic cotton—not polyester—inside a knitted Merino outer layer.  Long sleeves and a cotton lining make this the more insulated Reiff option, while the side-and-bottom zipper opens widely for changes.  Made in Germany; raw-fiber countries and closure materials are not fully disclosed.  Check room conditions before adding underlayers, and follow the handwash instructions to preserve the wool's fit. Materials: organic Merino wool outer knit · organic cotton fleece lining · zipper, button and small trims (composition not specified) $109.95 View product
Reiff Organic Merino and Silk Sleeveless Sleep Sack — Natural, 62/68 Reiff Organic Merino and Silk Sleeveless Sleep Sack — Natural, 62/68 WOOLSILK Why we recommend it: A wool-and-silk terry knit offers a soft, unpadded alternative to synthetic-fleece sleepwear.  The two-way zipper opens from the bottom for diaper changes while the sleeveless cut leaves layering flexible.  Reiff makes it in its own German factory; the raw fibers' countries and zipper materials are not specified.  This blend needs gentle handwashing and flat drying, so it suits families comfortable with wool care. Materials: 70% organic Merino wool · 30% silk · zipper and small trims (composition not specified) $84.95 View product
Superlove Merino All Season Baby Sleep Bag — Sylvan Navy Superlove Merino All Season Baby Sleep Bag — Sylvan Navy ORGANIC COTTONWOOL Why we recommend it: Superlove uses an organic-cotton outer layer and merino-wool lining for warmth in this unpadded sleep bag.  Adjustable shoulder snaps help the bag fit as your baby grows, while a two-way zipper makes diaper changes easier.  Check the neckline and armholes carefully, follow the layering guide, and air-dry after washing.  Wool does not eliminate the risk of overheating or guarantee longer sleep. Materials: organic cotton outer · merino wool lining · recycled-plastic zipper · metal snaps $122.00 View product
