30L Custom Dry Bags

Give the largest size in your collection its own carrying and packing brief. Evaluate a larger roll-top bag separately from a backpack with shoulder straps.

Model, materials, sample terms and scheduling are confirmed in the quotation.

01 / PROCUREMENT REVIEW

Decide how the customer will carry the contents

A 30L roll-top bag and a 30L backpack can solve different carrying tasks even when their capacity labels match. Explain whether customers move the bag over a short distance, carry it repeatedly or want a dedicated shoulder-strap system. Compare the reference designs accordingly. The existing mesh-pocket and printed dry bags are separate product families from the color-block, coated and textured backpack collections.

Review the supporting information

Factory photographs show the DryCross workshop. Use the sample approval checklist to record requirements for your exact order.

02 / PROCUREMENT REVIEW

Review the larger closed sample

Pack representative contents into the selected 30L sample, then complete the specified closure. Check access, remaining roll-top height and how the bag sits with that contents arrangement. A nominal volume should not be converted into a guaranteed weight limit. Identify a target load and an agreed evaluation method if carrying performance matters. Record the sample dimensions using a consistent measurement procedure.

03 / PROCUREMENT REVIEW

Assess pockets and hardware under the intended use

A larger bag may need a different arrangement of pockets, straps or attachment points from the small size in the same range. Review buckles, strap adjustment and the areas where the carrying parts join the bag. Explain which items would go in an external pocket and what protection they require. Do not treat an external zipper, mesh compartment or shoulder strap as evidence of a finished-bag performance rating.

04 / PROCUREMENT REVIEW

Build a size-specific branding specification

Check the logo scale on the actual 30L bag rather than enlarging artwork from a small sample without review. Describe how it should appear when the opening is closed and the bag is carried. If the design spans a panel, request the placement reference and allowed variation. Include retail labels and cartons in the approval set so the larger size is identified correctly in mixed-size orders.

05 / PROCUREMENT REVIEW

Confirm carton planning and reorder details

List 30L quantities separately from other capacities and identify each style, color and print revision. Ask for the proposed packing quantity and shipment measurements in the quotation; existing unit-package figures are not a complete freight estimate. Retain the approved construction and materials for reorders. Any substitution affecting the pocket, closure or carrying parts should be reviewed before a new production run is accepted.

PAGE-SPECIFIC QUESTIONS

Frequently asked questions

Does DryCross list a 30L roll-top dry bag?

The catalog lists 30L variants in its printed and mesh-pocket dry bag ranges. Confirm the exact SKU, sample and current order terms.

Which page covers a fully custom 30L backpack?

Use the custom waterproof backpack manufacturer page for a backpack development brief. Specify the carrying system as well as the target capacity.

Can a 30L bag carry 30 kilograms?

Capacity in litres is not a load rating. Agree the intended load and relevant sample checks for the selected model.

Can the 30L version share artwork with smaller bags?

It can be reviewed as one collection, but artwork size, placement and quantities should be specified for each capacity.
