Really like it. I initially bought a medium, then ended up buying a large as well for a different backpack size. It's very lightweight, waterproof, and surprisingly puncture-resistant. I use it as a pack liner inside my backpack to keep my gear dry during rainy hikes. It's much more durable than Nylofume bags, which tend to tear far too easily.

Highly Recommend Bag Liner
I recently used the Osprey pack liner (large, 70–100 liters), and I couldn’t be happier with its performance. It’s incredibly light, which is a huge plus when you’re trying to keep your overall pack weight down. Despite being so lightweight, it feels durable and well-made.
The fit is excellent—it sits perfectly inside my Osprey Aether 65-liter backpack without any bunching or wasted space. It’s clear that it’s designed with Osprey packs in mind, which makes packing and organizing gear much easier.
What really impressed me was its performance in tough conditions. I’ve used it in extreme weather, including heavy rain, and it kept all my gear completely dry. That kind of reliability gives real peace of mind when you’re out on longer trips or in unpredictable environments.
Overall, this pack liner is a simple but essential piece of gear that performs exactly as promised. Lightweight, perfectly sized, and highly effective. I highly recommend it to anyone who wants to protect their equipment in the backcountry.

Practical and lightweight.
Great, lightweight pack liner. Fits perfectly inside our canoe pack and keeps our gear nice and dry. The rectangular shape easily accommodates our stuff sacks, tent and mattresses without wasted space. Great to have that extra level of protection incase of heavy rain or a capsize.

Kept my stuff dry
A bit big for my 75L gregory baltoro pack but kept everything dry in the rain. easier to use than a garbage bag.
