Peak Design  Ultralight Packing Cube Bundle - Set of 3

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.

Small - fits 8 shirts Xsmall - fits 7 underwear Xxsmall - no idea yet what to put

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.

...when they fit your use case, they are absolute worth it! For me, the ultralight packing cubes are exactly what I needed. I own a 30l everyday backpack, and they fit like a glove. The regular packing cubes sit a bit too tight, if you tend to use the backpack's flaps side pockets. These don't. Three of them easily stack, four, if you force it. With my camera, an extra lens, tech pouch and toiletries, two of them fit on top. To put it in perspective, I can fit t-shirts, undies and socks for four days into one cube (s). That leaves another for a light sweater and some pants. But the real game changer is, that 1 the cubes are waterproof and 2 the passthroughs on the sides. I don't mean the loop, I mean the passthroughs where the fabric foulds and is stitched together. Because this way, you can pass the lower external straps of the everyday backpack though and put one cube under the backpack, without dangling around, like it would do, if you'd use the loops. It sits tight underneath the backpack. That expands your space by easily 6 to 10 liters! That's why I always carry one of those cubes in my backpack. If I should shop groceries and need more space, I can expand my capacities on the fly. I love it!

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 recently got the Peak Designs Ultralight Packing Cubes (set of three: S, XS, XXS) and they’ve been a game-changer for my travels. These cubes are incredibly stretchy, perfect for fitting all those loose odds and ends, ensuring nothing rattles around in my bag. As expected from Peak Designs, the quality is top-notch. I use them frequently for my tech consulting trips, and they make packing so much more organized and hassle-free. Highly recommend!

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 love the new eclipse color! I really hope you make some of your other bags with it! As far as size, the Small is perfect for a pair of men’s pants rolled up and maybe a couple t-shirts. Which is great for spare clothes when on a two or three day hike. Also great for an extra couple shirts and socks in your carry-on. The XSmall bag is perfect for organizing 8-10 thin socks.

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.

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.
