The 30L model in the 3P group

The source for Upgrade 3P Backpack lists 32L, 800D Oxford material and 1.1kg. Large 3P Backpack lists 34L, 800D Oxford material and 1.2kg. This 3P Backpack entry lists 30L, 600D Oxford and 0.85kg. Keep those separate model references in your quotation if you are choosing between capacities.

The figures establish differences in the recorded capacity, material designation and product weight. They do not establish a maximum carrying load or how the capacity was measured. Request outside dimensions and the measurement basis before selecting a bag to accommodate a fixed set of equipment.

Check the compartment and attachment layout

The description names multiple compartments and hidden pockets, with an outer pocket for access and webbing on both sides. It does not state the dimensions of individual pockets or a standardized attachment spacing. If you have a pouch or organizer that must fit, send its dimensions and ask for the relevant area of the sample to be measured.

A thickened back pad is described, but no padding thickness or measured comfort result is supplied. Inspect the sample’s back panel, straps, closures and internal layout together. The capacity figure cannot tell you whether the loaded bag will arrange your particular contents the way you intend.

Separate the fabric description from a bag rating

The source calls the material 600D waterproof Oxford. This page retains the 600D Oxford designation as the material reference; no test method is supplied for the completed bag’s seams, zippers or water resistance. If exposure to rain is part of your purchasing specification, ask for the required finish and appropriate supporting test information.

The lining is listed as polyester/cotton, without a blend percentage. Confirm the lining composition and finish on the sample specification. For freight planning, request the finished packing list rather than multiplying the listed 0.85kg by quantity and treating the result as carton gross weight.

Plan the sample and quotation

Compare the backpack and bag catalog before finalizing your capacity mix. Send the 3P Backpack reference with the quantity, preferred color and required compartment measurements. Include any logo artwork and packaging changes as separate requests, and ask the quotation to identify the exact version approved from the sample.
