Medium swaddle sleep sacks are typically listed at about 26–30 inches long and sized for babies weighing roughly 16–24 pounds. Individual brands may vary, so check each product's size chart before buying.
Most medium sleep sacks use smooth zippers—either full-length or 2-way zippers—with zipper guards for safety. A smaller number pair a covered zipper with a snap-front or fold-over panel for added protection.
Medium wearable blankets typically feature wide arm openings and a roomier hip or wider base to allow natural kicking, leg movement, and hip motion while sleeping.
Many medium swaddle listings specify a lightweight 0.5 TOG, marketed as temperature-regulating. TOG values can vary by brand and fabric, so check the product details for the exact rating.
Follow the care label, but most medium swaddle sleep sacks recommend machine washing and tumble drying. Use the manufacturer’s instructions for water temperature and drying settings to preserve fit and fabric.
Product listings commonly show medium sleep sacks in the 26–30 inch range (some list about 30 inches). Because measurements differ by brand, confirm the exact length on the item's size chart.
Medium sleep sacks are often sold in 2-packs, though single units and other multi-packs are also available. Check the product listing for exact pack quantity.
Common sleeve types for medium sleep sacks include sleeveless designs and wearable blankets with wide arm openings that leave the arms free for movement.
