A buyer searching for Dry Sack is usually trying to stop a bad substitute. A bag is specified by volume, the load, the fabric, and the hardware that fails first. The notes below are selection criteria for a Dry Sack. They are not a catalog promise. Confirm every rating on the current datasheet, drawing, or test report for the revision you will receive.
What has to be true of Dry Sack
A bag is specified by volume, the load, the fabric, and the hardware that fails first. For a Dry Sack, start from the duty, then the interface to the rest of the machine or the room, then the document that proves the claim. A lower price that leaves one of those blank is a different product.
Dry Sack is easy to confuse with Laptop Backpack. If the quote could be read as either, add the line that separates them: the rating, the fitment, or the standard named below. Link the drawing number to that line so receiving inspection can reject the wrong one.
Numbers that change the quote
| Line | What to write for Dry Sack |
|---|---|
| Hardware | Zipper, buckle, and wheel rating. |
| Compartments | The organization the user actually needs. |
| Branding | Logo method and the artwork revision. |
| Volume and fit | Liters, or the laptop and contents it must hold. |
| Fabric | Denier or material, and a water claim only if a test is named. |
| Load | Carry weight and the strap or handle that takes it. |
How to compare two offers
Lay both quotes for Dry Sack on one sheet and line up hardware, compartments, and branding. If a cell is empty, the offer is not finished. Ask for the missing line in writing. When those match, the honest difference is lead time, the test evidence, and who carries the warranty. Do not average a fully specified Dry Sack with a cheaper line that omitted hardware.
Documents worth having before the deposit
Ask for a bill of materials for fabric and hardware. The file should name Dry Sack and the revision, not only the supplier’s homepage. A factory quality certificate such as ISO 9001 can sit beside that file. It does not replace it.
Failures that show up after delivery
- Using an untested waterproof word on a fashion shell.
- Ignoring zipper cycles on a daily bag.
- Specifying liters and forgetting the laptop sleeve dimensions.
On a Dry Sack, the expensive version of the first mistake is discovering it after the goods are in the crate. Put the rejection condition in the purchase order while the supplier can still restate the offer.
A worked RFQ line
Use this shape, then replace the brackets with your duty: “Dry Sack — Write volume, load, fabric, hardware, and logo method.” That sentence is a template, not a rating of any brand. If a supplier’s datasheet uses different units, convert them onto this sheet so the next offer can be compared.
Where words like waterproof / IP65 belong
Searches often add a constraint to Dry Sack: waterproof / IP65, or explosion-proof / ATEX. Keep those on this page. IP65 in IEC 60529 means dust-tight and protected against water jets. Write that code if hoses are the real exposure. The word waterproof alone does not name a test. ATEX or IECEx is a certificate for a zone, a gas or dust group, and a temperature class. An IP rating does not grant it. Skip the mark if the site is not hazardous. If you need a third constraint, add it as another line on the same drawing. A second URL that only swaps the adjective does not give a buyer a second fact.

Questions buyers actually ask
What should an RFQ for Dry Sack include?
Write volume, load, fabric, hardware, and logo method.
Is a cheaper Dry Sack the same part?
Only if hardware, compartments, and the documents match. A missing line is a different offer.
Do waterproof, OEM, or IP words need their own page?
No. For Dry Sack they are extra lines on this specification. Ask for the test or the drawing that gives the word a value.
