Some months ago I was visiting Gamletorvet Sport @Gjøvik, and I fell so hard for this harness (which is kinda funny since we do not have kids) you can use for carrying your precious in. Thought it should be shared, and a way of getting it if you are want to take your kid out in nature. Like we all should every weekend..
I have not tried it myself, but from the reviews I have read online the harness gets a lot of positive feedback.
Label: Osprey Poco AG Premium
It comes in a lot of different colours.
