AER Go Pack vs Ebags mother lode

These are going to be more suitable for ‘true’ one bagging (ie when you travel without a checked bag). If you decide to opt against a checked bag, perhaps look at a packable day bag and one of your options above, or take a look at the Peak Design Travel Bag, as this is designed with photographers in mind, is effectively a big bucket of a bag, and can expand from 35-45l (although I think when expanded to the full 45l it is slightly too big for most airlines). For a daily carry, you ideally want to be looking at something 25l or less, even under 20l.

At the current price, its a fine small duffel bag at about an effective 20 liters; its capacity is smaller than the specs would lead one to believe. It might be a fine overnight bag for a small child or a petite person but I would not recommend that use for a large adult unless its for very light weight summer clothes — shorts, T-shirts, a pair of sandals & very small toiletry kit.
