I use the xxs one for packing snacks on the go. Works great for that purpose and the fact that is weather resistant was a defining factor in my buying decision for this use case.

I bought one white bag 3 weeks ago ( before they sold out so fast). its volume is bigger than expected, very lightweight indeed. Very happy with it.

I got the small cube as a gift and love it. I like the two separate compartments separated by a waterproof layer. This means I can keep clean and dirty in the same cube. And since our next trip is to India, I can use it to keep shoes on one side (it's expandable!)and clean socks on the other. The quality appears excellent, giving an impression of extreme durability. The ability to carry this as a sling with the optional strap is a plus.

I bought several of these packing cubes with my outdoor backpack 25L and I am very satisfied with them. They are strongly built, the hooks and the zippers feel very good in the hand. I just wished we could wash them in the washing machine but it appears it is not reommend (label instructions say « surface cleaning only »).

I wanted something strong but really light to be able to take on my trip away. These fit the bill, I bought the waterproof version and the mesh version. I love the fact I can clip them securely to the outside of my pack as well when I need snacks or to dry something in the mesh bag.

I bought a couple and have been super happy with them. They don't compress like the regular one's do, but the fabric is really breathable, and light. They also roll off, and can be stowed when not in use. I typically used one of them for fresh and the other for used clothes and they've been so durable, and light. I've overpacked them on every trip since I've got them, and never had to worry about if it might be too much. Definitely recommend it.

Bought this for backpacking travel and it keeps my pack perfectly organized. I keep extra empty cubes for when I get more stuff and then I can mount them on the outside of the pack too. No complaints at all on these.

The zippers feel amazing. The fact that it's also a sling is great so now I can use it every day vs just on trips

I got single XXS UPC in fabric. This item is great for both travel and everyday carry. For travel, I'm carrying Tech Pouch + UPC XXS, in tech pouch there is all the staff I carry for travel. And ? just put cords, charger, powerbank and SD card reader in the packing cube (XXS) and carry it around.

Picked this up from the Peak Design Amazon store on a whim to fill out my order of a medium and small regular packing cube. I wasn't sure how I'd use it but figured that for the price it would be good for some extra organization. I was surprised by just how much this thing ended up being able to hold! I used it for all of my electronic accessories (chargers for phone, MacBook Pro, and kindle; my extra power bank; a few ink pens; air buds and wired iPod headphones). It could have stretched to fit even more yet it took up so little space. Great little pouch that is really versatile. I'm considering buying the strap so that I can also use it as a sling. Well worth the $15.

Scored these a set on the Black Friday week sale for an upcoming trip for me and Christmas present for my father. They weight practically nothing, the stitch and zipper seem high quality. Can't weight to put them to use.

So stoked these exist... I realized this is exactly what I needed: small, light storage for odds and ends that pack down small and light, but ALSO each of them can be used as a day sling WHAT!? So great--looking forward to taking all 3 with me and having options for a trip down to the pool to around town, or on a trail. Also these can be strapped to your bag (I have the 45L travel pack) for quick access so it's a no-brainer for me to get these.

I bought these for a backpacking trip and they were so useful I've began using them daily already. Each size has its own use and I'm surprised at the ease of access and sturdiness of zippers and fabric.

Bought the three pack for a recent trip and it was great. Smallest size is great for packing medications and toiletries, larger sizes ideal for organising other items. Add a strap and they will also double as a sling bag.

I've bought 3 black ultralight packing cubes. Sizes: Small | XS | XXS. They are indeed featherlight, since they weigh in at 43 g | 27 g | 20 g. The bags are not see-through which is great for taking it out. i will use them for packing and hiking. For my fellow Eastern European buddies, the small bag will fit a full adidas tracksuit and a book. For all other people this means it will fit two average size shoes (mine are 43 EU, still fits) Very easy and simple design, yet sturdy. overall happy.

I bought three of these in XXS and XS sizes. I planned to use them for cords, meds, and other small misc items when traveling. I've found myself reaching for these bags for every day use also. Great to put some small gear and toss in the daypack when out photo-hiking. Also makes a good wet sack for my bathing suit. I can think of so many uses for these bags. They are well made and roll up very small when not in use. Great that they can clip to a belt loop or another bag, or be used with a strap.

I commute in my bike a lot, and during the hot months I end up carrying extra shirts, deodorant, bug spray and a bunch more doodads that usually just bounce around in my backpack. I bought three of the UL Packing Cubes and I can chuck everything that's loose and carry it more comfortably. And what's best is that attaching an external strap makes it the perfect carry solution for simple walks when I just want to bring my phone and sunglasses and don't need a whole bag. Materials are quality and the eclipse color is beautiful.

I love my xs packing cube, it fits in my everyday carry bag and is always ready to put my valuables in to keep dry when I get caught in a downpour while commuting on the bus.

I used to throw all by bathroom/toiletry items in one big bag, and every night I had to dump the bag. I've bought an XS and XXS cube - they will be great for differentiating and organizing. One cube is mesh so anything that might be wet can breath. I'm thrilled to have them, and expect more will be added.

Transform your cube into an ultralight sling by attaching an adjustable carry strap or PD camera strap (both sold separately) to the Cord Hook carry loops. Additionally, the cubes can be mounted externally on any Peak Design bag using the two external carry strap pass-throughs, adding a new layer of modular organization to your travel gear.
When not in use, the Ultralight Packing Cubes fold completely flat and can be rolled up and secured with the elastic zip pull cord, making them easy to store in your pocket or bag. The Cord Hook loops also serve as a counter pull for effortless opening and closing. These cubes are Fair Trade Certified and 100% carbon neutral, reflecting Peak Design's dedication to ethical manufacturing and environmental responsibility. With their thoughtful design and practical features, these packing cubes are an indispensable addition to any traveler's toolkit.
