Sherpa Go Go Bag®


The Sherpa Go Go Bag® is a revolutionary design and a world-first in terms of how the lining is made. The luxuriously soft and dense merino lining provides the warmest and snuggliest micro-climate for your baby, as well as providing a natural cushion while your baby sleeps. The merino fur lining acts as a buffer against changing room temperatures – keeping your baby warm in the coldest of temperatures and cool in the warmer climates. Any moisture is absorbed and released away from your sleeping baby; in essence your child becomes perfectly adapted to their sleeping environment.

Our thickest merino wool lining yet is held together with a mesh of merino and extremely fine polyester threads to help create a secure backing for our plush merino wool. This provides a far superior stability to this merino wool fleece lining by doubling it in strength, providing the ability to naturally move and reset. The result of this ground-breaking design, means that only 100% merino touches your baby’s skin providing the same natural comfort as all of our products you have come to know and love!

We also recommend our Duvet Weight and Standard Weight Go Go Bag™ as a 100% natural option to our range.

Founder and designer Amie Nilsson continues her dedicated research and development work alongside her team to find natural alternatives to the use of man-made fibre in the continual effort to offer products that help reduce our impact on the environment.
