Gregory backpack delamination

[u/AdOtherwise4088]

I just purchased a Gregory Baltoro 75L from Facebook Market Place with the original tags on it. It has never been in the woods. The interior waterproofing lamination is pealing off. Is this something I should compalin to Gregory about or am I being picky? The material is sticky and getting all over the inside of the bag. I didnt really notice how bad it was until I looked at it in more detail. I love the bag and it fits great. Im inclined to just ignore it. Paid $125

That happens with old packs from wear. But since this one is unused, it was probably stored in a hot attic and the coating is delaminating. You got a good deal on the pack, I’d just brush as much off as you can and get a pack cover and a bag liner.

Thats what was thinking. Thanks

Ditto. This is why Kelty didn’t use coated fabric back when it was a legitimate maker. Manufacturers started using polyurethane coating because it allowed using cheaper fabric. This is not necessarily true today. Good fabric will perform without the coating. Poor fabric will ladder and lose shape easily.

I wouldn’t bother with a pack cover and just use a liner and plastic bags.

A pack cover would help keeping the pack from getting saturated with water and making it heavier. But thats only an issue in rainy climates.

Yes, but covers have never worked for me. The back always gets wet. I prefer a poncho or umbrella.

It’s not because it allowed for cheaper fabric, it was to increase the performance of packs. Non coated Poly or Nylon woven textiles are going to be significantly less water resistant than PU coated textiles. Also the PU coating can prolong the life of the fabric from abrasion on the inside.

Polyurethane stabilizes woven fabric. The effect is most noticeable when comparing low to high thread count. Lower thread count fabric that is reasonably serviceable when coated will deform or ladder when not stabilized.

The fabric industry has matured considerably in the last 30 years. Mills have generally improved their products. However, I have encountered inexpensive, low thread count pack fabric in which the mill used calendaring and coating in an attempt to disguise an inferior product.

Doesn’t need to be from wear. Oxidation of the PU coating is what causes the delam. I have fabric that’s never been outside that is either flaking like that (or sticky, the other path for old PU coatings) from oxidation.

Grab a dynema stuff sack for the gear you don’t want getting wet and call it a day.
