ToddlePak Backpack Harness
8.1/10 overallAround £20
A small backpack with a detachable rein lead, designed to feel like a toddler's own bag rather than a harness.
The verdict
The Trunki ToddlePak is a small character backpack with a detachable rein lead, around £20, that toddlers accept far more readily than a plain harness because it reads as their own bag rather than a restraint. It costs more than a basic harness and its strap-mounted rein attachment is less rigid than a back-clip design, but it's a strong pick for a toddler who resists wearing reins.
The ToddlePak reframes the whole idea of a rein: it's primarily a small, characterful backpack sized for a toddler, with a rein lead that clips on when needed and detaches when it isn't, so on days out it can simply be worn as a normal little backpack the rest of the time.
Against the plainer Lindam harness in this category, the ToddlePak costs more but tends to see far less resistance from toddlers who are reluctant to wear a harness — because to them, it reads as their own bag rather than a restraint, which meaningfully changes the day-to-day battle of actually getting it on before you leave the house.
The backpack does have a small internal pocket, useful for a snack or a favourite small toy, which adds genuine everyday utility beyond the safety rein function itself, unlike a harness with no storage.

Frequently asked questions
Will a toddler who resists harnesses accept the Trunki ToddlePak?+
Yes — it scores a perfect 10/10 for toddler appeal, framed as "their bag" rather than a restraint, so toddlers generally accept it readily compared with a plain harness like Lindam's, which tends to see more day-to-day resistance.
Is the ToddlePak useful as an actual backpack?+
Yes — the rein detaches so it can simply be worn as a normal little backpack the rest of the time, and it has a small internal pocket useful for a snack or a favourite small toy, adding everyday utility beyond the safety rein function.
How secure and comfortable is the ToddlePak?+
It scores 7/10 for security of clasp and 8/10 for comfort and padding — secure in normal use, though the rein attachment point (clipping to the backpack strap) is less rigid than a back-clip harness design. The padded backpack straps are comfortable over longer outings.
Is the Trunki ToddlePak worth the extra cost over a basic harness?+
It's more expensive than a basic harness set like Lindam's, and the backpack adds a little bulk. The trade-off is worthwhile if your toddler is reluctant to wear a plain harness, since the backpack framing meaningfully changes the daily battle of getting it on before you leave the house.
