ergoPouch Sleep Suit Bag Cool Pouch 0.3 TOG

The ergoPouch Sleep Suit Bag Cool Pouch (0.3 TOG) is a lightweight, TOG-rated wearable sleep bag that converts into a sleep suit with legs, giving you one garment that grows with your little one from cot to pram and back again. Made in soft organic cotton with a light 0.3 TOG rating, it's designed for warmer summer nights, with ergoPouch suggesting a room temperature of around 24–26°C. Because it's a wearable sleep sack rather than loose bedding, it replaces the need for blankets in the cot.

What sets this Sleep Suit Bag apart is its four-way zip system. It starts as a classic sleeping bag with a roomy, bell-shaped bottom, then unzips to separate the legs into a suit — handy once your child is on the move and wanting more freedom to shuffle, stand or walk. That flexibility also makes the transfer from pram to cot a little easier, and the separated-leg mode can be used with a five-point harness.

A convertible design that lasts longer

The ability to switch between a sleeping bag and a legged suit means the garment keeps working across stages rather than being outgrown quickly. Separating the legs allows for comfortable movement, and ergoPouch notes that the leg configuration helps reduce the risk of cot-climbing injury. Grip pads on the feet give little walkers some traction, while the covered arms keep shoulders warm without loose covers.

Made for comfort and easy movement

The outer and lining are 100% GOTS-certified organic cotton — gentle on delicate, sensitive new skin — with an organic cotton filling for warmth. Stretchy side panels (95% organic cotton, 5% elastane) and stretch inserts let baby move freely and stay comfortable, and the fabric carries a smooth 400 thread count for a soft feel. A full zip enclosure with a design that helps protect the skin makes dressing and nappy changes more straightforward, and the set includes a room thermometer to help you judge whether the TOG rating suits your nursery.

Sizing

Available across four sizes to fit from around 3 months through to 6 years:

Best For

The ergoPouch Sleep Suit Bag Cool Pouch (0.3 TOG) is a great option for parents who:

• Want a lightweight sleep bag for warm summer nights and rooms around 24–26°C
• Have a baby or toddler on the move who benefits from separated legs to stand, shuffle or walk
• Prefer one convertible garment that adapts from cot to pram and can be used with a five-point harness
• Like the reassurance of GOTS-certified organic cotton against sensitive skin

It may not be the best fit if you're looking for a warmer garment for cooler nights, in which case a higher TOG rating would suit better.

Care

Gentle cold wash, low tumble dry, moderately hot iron. Dry-cleanable.

Disclaimer

A wearable sleep bag is designed to replace loose blankets in the cot. Choose the size that fits your child's current weight and height, check that the neck and arm openings fit correctly so the garment stays in place, and follow the ergoPouch instructions and current safe-sleep guidance. Use the included room thermometer alongside the TOG rating and adjust base layers to keep your little one comfortable.
