I an so looking forward to using these cubes on my next trip (in a month). I have packed and repacked them several times and am very impressed by the durability and space. The design fits perfectly in my backpack as well.
I bought four of the small packing cubes a few weeks ago before a two-week trip to Europe. I had bought and returned a set from Eagle Creek because they seemed flimsy. This Peak Design style is awesome. Not flimsy, so they are easy to pack, but not so thick that they take up a lot of space. The compression feature is pretty easy to use and I love the opposite compartment for dirty clothes. I mostly use a carry on roller board and mine can fit three small on one side and then another small (with shoes and my toiletry bag) on the other side. I packed tops in one, bottoms and dresses in another, undies and PJs in another, and swim suits and workout gear in the last one. I stayed super organized even after 8 different hotels in 13 nights. My boyfriend was jealous haha. A couple of other sizing notes: I had originally bought the medium but it was just too big. Unless you’re a large person or want to pack sweaters, I would buy smalls. Also I had read that the 30L Peak Design bag (which I have) can fit 3 smalls (aka 3 units), but it can actually fit more because they can stand on their sides. We’ll see how they hold up, but so far super happy with my purchase!
I always thought if you had to use a travel pouch like this, it meant you were over packing. Absolutely not the case. These packing cubes have revolutionized how I pack more efficiently. Everything has to fit into a small and medium cube which requires thoughtful decisions and makes traveling so much easier than if I packed directly into my bag (it's easier to pull out just the hiking clothes versus dinner attire). I can’t believe I didn’t try the sooner, but I know I won’t travel without using them again.
For reference, in the small pouch, I recently packed a pair of pants, a long sleeve wool sweater, two T-shirts, a lighter weight sweatshirt, pair of socks, a pair of shorts and underwear. This was a tight fit but it was easy to open and close the pack as needed.
The only thing I don't like is that the "dirty" zipped area is pretty small: once I put a t-shirt and socks in there, it starts impacting how easily I can zip the rest of the pack. It may just take more work in folding and getting the dirty clothes in there properly but that's the only negative to these cubes.
I bought these a month ago for our camping trip to Machu Picchu. They helped us tremendously to easily and quickly find our clothing, toiletries and gadgets everyday! We didn’t have to hunt for stuff. I love these!
