I nabbed one, just because it's osprey and they have a crazy good warranty I sent in a backpack that was abused by my son for 2 years of high school pencils poked holes through it and zipper broke etc due to him being crazy rough with it.

They sent back a brand new updated model no questions ask.

I have a ton of their gear and while some design decisions i question (super bad water bottle holders on some packs) i generally love their stuff.

These kinds of bags are also not submersible in my experience its for heavy rain, or on kayaks, etc where heavy splashes etc occur and you need to roll them the correct number of times very tight

I have a bunch of Osprey gear and agree with prior comments on quality and customer service, but will also add for generic stuff like dry sacks, there are so many cheaper and comparable products out there on Amazon, Aliexpress, etc. I won't risk linking Aliexpress products here but it took me 2 mins to find a 40L dry sack for $5 and 70L dry sack for $6. I'm sure I could find cheaper if I wanted. And it is the same identical ones I have been using for 5+ years, no complaints.

They work well but the internal silicon/plastic material will disintegrate eventually

For dry bags I'd usually suggest generics on Amazon, but this price is competitive with those.

There's a lot of applications for these besides kayaking:

- Hand laundering clothes while backpacking
- Separating items in a cooler
- Poor man's cooler bag
- Water carrying while camping

etc

LOL, and then you get white flakes on everything! That limits the life/usefulness of these types of bags

Having recently purchased a Farpoint 40L and Farpoint 15L daypack and become a major fan I'll pick one of these us as well.
