Cocoon Swaddle Sack

Cocoon Swaddle Sack

Cocoon Swaddle Sacks are designed to be both easy to use and difficult to escape from. This zip-up swaddle is TOG rated for warmth to keep a baby snug and securely swaddled without the need for complicated wrapping from day one. Being TOG-rated means that the warm 2.5 TOG swaddle can be used on its own in room temperatures between 63-73°F with no blankets in the bassinet or cot to make this a safe sleep option for a newborn or baby.The 2.5 TOG also makes this an ideal warm winter swaddle for cold weather. The chest area is 1.0 TOG rated to prevent overheating and allow for full chest expansion when breathing. Parents can layer up underneath the winter swaddle as needed for warmth, and follow our handy FREE room thermometer and what to wear guide included with the product to help them dress their child appropriately. We recommend pairing this with one of our TOG-rated Rompers underneath (sold separately).

The 2.5 TOG Cocoon Swaddle Sack is our warmest winter swaddle.

The Cocoon Swaddle Sack is made from and filled with GOTS certified organic cotton, with elastane in the outer fabric and bamboo in the lining. This means it's firm enough to restrict startle reflex while still allowing stretch and movement for healthy growth.

Ortam sıcaklığı ve TOG:

What is TOG?

A TOG stands for Thermal Overall Grade and is a unit of measurement for insulation and warmth of sleepwear and bedding. Put simply, the lower the TOG rating, the lighter the fabric. The higher the rating, the more padded and insulated it is. With TOG-rated sleepwear, you do not need additional blankets in your child’s sleep space.

How should babies be dressed during sleep?

Babies sleep better in natural fabrics because even if the temperature of the room changes, in natural fibers your baby's temperature remains constant throughout the night and as a result, their sleep is not interrupted by sweating/chills. Natural fabrics help them sleep warm on a cold night and cool and comfortable on a hot night. In ergoPouch sleepwear, only natural fibers such as organic cotton and bamboo are used because these materials are the most beneficial in keeping the body at an even temperature. The filling material of all the overalls with inner filling is 100% organic cotton.

We usually recommend that you start by wearing a thin undershirt underneath your swaddle or sleeping bag. As every baby is different, please check before choosing an underwear:

What is the temperature in the room?
When determining the temperature level of your baby's room, please keep in mind that it is likely to be at different temperatures during the day.
How warm is your baby?
Check your baby's chest or back. It is normal for babies to have cold arms or legs as their blood circulation is more intense at the extremities. Your doctor will confirm this information. The choice of short/long sleeve underwear or ergoPouch sleepwear is up to you.

TOG examples

0.2 TOG is the thickness of a thin combed cotton, 1.0 TOG is the thickness of a thin cardigan without filling and 2.5 TOG is the thickness of a quilt. In general, our mothers who use quilts for night sleep prefer our 2.5 TOG sleeping bags. 2.5 TOG overalls do not have padding on the sleeves. Our families who use quilts or blankets generally prefer 2.5 TOG. Most of our families prefer 1.0 TOG in spring and 0.2 TOG in summer. In addition, our 0.2 TOG and 1.0 TOG can be layered under all our other ergoPouch products to ensure maximum comfort.For example, if the room is between 22-23°C...1. Put on a thin undershirt (or 0.2 TOG ergoPouch sleepwear)2. Put on 1.0 or 2.5 TOG ergoPouch sleepwear over it, providing back/chest control.3. You can wear a butterfly cardigan over your swaddling bag, especially if the temperature drops at night.*There are no ergoPouch sleeping bags suitable for use at temperatures of 28 degrees and above.
