The Le Petit Derriere (LPD) is, as you probably guessed, the smaller version of our waist/sling/shoulder pack, Le Grand Derriere (LGD). 

 

The resulting size of the LPD is about 80% the length of the LGD on any given edge, and about 60% the total volume. (If you were absent that day in geometry class, you're not alone.) Side-by-side, the LPD and LGD don’t seem all that radically different in size. In profile, the difference is quite a bit more noticeable. 

Time to choose your own adventure. Do the features and style of the LGD / LPD speak to you? If not, perhaps choose the path that takes you back to our collection of shoulder bags and waist packs or travel on to a new universe entirely. 

Feeling spoken to? Your next quest is to determine which is the right size for you. And that comes down to a matter of capacity. Do you need the 6.2” depth / 8 liters of the LGD, or will the 4.7” depth and 4.6 liters of the LPD do the job? One way of thinking about it is: the LGD can fit a light jacket, whereas the LPD doesn’t. 

Other than that, the LPD has all the same features as the LGD. Knock yourself out.
