Product Type: Diaper Bags

The base extends when you need the room and folds back when you do not. That is the difference between a bag that is always large and one that is large only on the days that call for it.

It Expands Only When You Need It To

A fixed large diaper bag is oversized on a short errand and right once a week. An expanding base gives you both shapes from one bag: compact for a school run, extended for a day out or an overnight, with a wet area at the bottom that only exists when you unfold it.

The base unfolds to add depth without changing the footprint on your back.

Four Ways To Carry One Bag

Removable straps turn it into a backpack, handbag, crossbody or shoulder bag. That matters more than it sounds on a bag this size: a full diaper backpack is uncomfortable on one shoulder, and a handbag is wrong for a hike, so being able to switch mid day is the feature you use most.

A Laptop Sleeve In A Diaper Bag

The sleeve is the reason this works as a single bag for a parent going back to work. You are not carrying a laptop bag and a diaper bag, which on a commute with a child is the difference between two hands full and one.

The Wet Area At The Base

A separate waterproof bottom pocket keeps a soiled change away from clean clothes without a separate wet bag. It is the compartment people forget to look for and then use every single outing.

Where An Expanding Bag Costs You

Mechanisms add weight and seams, and this is a larger bag than a simple backpack even when folded. If your outings are short and you carry two bottles and a change, a compact bag will be lighter every day and this one will be right occasionally.

Expanding Backpack Questions

Does it stay expanded once unfolded? No, it folds back. The extension is there when you want it and out of the way when you do not.

What size laptop fits the sleeve? The sleeve is sized for a standard work laptop rather than a large desktop replacement.

Are the straps removable? Yes, which is what allows the four carry modes.
