Osprey Ultralight 20L Dry Stuff Pack, Waterfront Blue

While about 1.5 times the volume in hand when "enfolded", this waterproof version of Osprey's ultralight stuff pack is only 0.44# versus 0.33# in weight. It also holds 20L versus 18L. (I have and use both.)Of course, both styles aren't intended to be heavily loaded daypacks or backpacks, but are wonderful additions to the luggage of any traveler who might intend to take a day long walk in an urban or outdoor location while on holiday, allowing carrying an added layer or two, a few important items, lunch perhaps, and a bottle of water or two.This version gives assurance of being water-proof since access to the interior is protected. The "standard" ultralight stuff pack's zipper is exposed, so, in a HEAVY rain, water can permeate and enter the interior. The material of both packs is waterproof, so I imagine that a waterproofing/waxing of the standard stuff pack's zipper and supporting fabric would improve that pack's rain resistance even more.For me, the "standard" Osprey Ultralight Stuff Pack is a no-brainer always take item, with just-in-case use and optional short outings in fair weather in view. This water-proof version, on the other hand, is taken when intentional use during trips of many days of whatever weather happens is a part of the plan.

It held up well in 8 hours of rain in Iceland on a hike. It never wetted out, and kept my camera, and fleece completely dry the entire time. I used it on several occasions without a second thought after it held up hiking to Drangajökull and through Hraunsvatn 🫶

Great backpack! Nice size for extended travel, FAA compliant for carry on. Held up well for extensive travel through Scandinavia. Highly recommend!

I don't know why I thought this would be anything more than a glorified sleeping bag stuff sack, but that's kinda what it is. I'm OK with that for now so long as it does what it's supposed to, but I need to use it more before I can have a final determination on that. I'll update this review accordingly once I've had time to put it through it's paces.So far, not super impressed with the storage space. It feels less usable than I expected, being fairly restricted in the width department - the main storage compartment is a bit of a narrow tubular design.I am happy with the fact that it came with a means to clip the straps together though. My use-case is I ride a motorcycle and need a packable bag to be able to pick something up or carry something extra when I'm beyond capacity. This makes snapping the shoulder straps together and absolute must for me, because there's no such thing as "readjusting" while riding a motorcycle - it requires all 4 limbs. So a sliding shoulder strap can literally become life threatening in a well crafted final destination scenario.It doesn't seem like a very durable material but sometimes things can be deceptively durable so I will include this with my update as well.Finally, for a packable bag I like the look. It's hard to make these things look cool, but I'm pretty happy with how it came out. The color is very vibrant which is well represented on the pictures.

Perfect bag for camping day trips. Compacts down to pocket sized. Waterproof..highly recommend.

Great day pack when traveling. Packs small for stowage.

Love this bag! Very surprised by its compact design. Get one. You will not be disappointed.

Osprey always gets it right. This bag is my go to travel day pack. It takes up very little space, stays dry, holds a ton, and is comfortable to wear. Get one.
