Planning a hiking trip somewhere notoriously wet and rainy like Olympic National Park? The Osprey UltraLight is a great way to stash your clothes inside your backpack. Water-repelling fabric and a tight roll-top closure system will give your gear the added "just-in-case" protection that might be the difference between happy feet and soggy socks. Weighing in at only 1.6 ounces, it's perfect for backpacking trips. The only downside to this product is the thin, delicate fabric. Shaving ounces also costs durability, and this product absolutely requires the protection of an outer pack.

Our Analysis and Test Results
The Osprey UltraLight is made of 40D nylon ripstop. The 20L size we tested is 17-inches tall x 10-inches wide x 6-inches deep. This flat-bottomed rectangular bag features a classic roll-top reinforced with a stiff plastic lip and has a total volume of 20-liters.
This metric makes or breaks a dry bag's performance scores, and the UltraLight does astonishingly well in this category, especially considering the small hole it sustained before our more rigorous testing! Full-on sustained submersion did allow water to creep into the interior, but only a few small patches of our testing towel got wet. Our gear was quite a bit wetter after it was dragged through the lake, but the contents were far from soaked.
Ease of Use
The UltraLight looks a lot like your typical packing cube. Its rectangular shape and square bottom make it easy to neatly pack folded layers. Unlike more traditional packing cubes, however, it doesn't zip down the sides, and the top only entry makes it slightly less convenient for retrieving the internal contents.
There are no special features to assist in carrying this model, but its also necessary to carry it inside a larger backpack for protection. The classic design of the UltraLight also makes it a poor choice for a sleeping bag. Stuffing a bag inside and compressing the air out is no easy feat.
The most remarkable feature of the UltraLight is the small webbing loop at the bottom of the bag. It provides a small, yet sturdy handle to extricate this model from a well-stuffed backpack. Other, similar models we tested offer no such helpful features and often require two hands to slide out.
It has a standard roll-top design with a lip that is reinforced with plastic to help give it shape when rolling. It also features a single small D-ring at roll top. Since this model is meant to be stored inside another pack, we didn't miss more robust lash points.
Unfortunately, this metric is the UltraLight's undoing. Reducing weight also means thin material. Our product sustained a small puncture-like tear in the bottom early on in our testing. How and when it sustained this casualty is unbeknownst to us, but no significant force was rendered.
This model is priced in the mid-range amongst standard packing cubes that offer zero protection from the elements, and on the low end of actually waterproof dry bags. With that kind of value, we're pretty sure you'll think its a great deal when you pull on a warm and cozy pair of dry socks before you crawl into your sleeping bag.
The Osprey UltraLight offers modest protection from water and helps assure you will have a dry change of clothes at the end of a long day hiking. It's lightweight and designed just right to serve as a great backpacker's packing cube.
