Peak DesignUltralight Mesh Packing Cube, Charcoal, Stretchy Mesh Luggage Cube with Strap Attachment Points and Luggage Pass Throughs, Zipper Opening, Travel Organizer for Men and Women, Size M

Peak design make the absolute best compression packing cubes. The quality of the materials are top notch, very durable and easily foldable to put away when not used. The zipper is excellent, never gets caught up when zipping, easy to pull along without struggling to hold and pull along and being made from high quality materials. This packing cube has been used on multiple trips and still going strong and looking good. Some people may criticize that there is no window to see what is inside but having used that type as well and from experience it doesn’t matter. Why? Because even with those types of packing cubes you will either be only able to see the top item stored or if rolling items up and storing horizontally not be able to see everything so finally you will end up having to open up the bag anyway. Lastly the compression factor in this design is fantastic, you will be amazed with what you can fit into one. The Peak Design packing cube is money very well spent for a high quality product that will last a looonngg time.

I’ve been using packing cubes for 15 years, and this is the best I’ve found. Even though Peak Design calls it a “medium”, it’s a large compared to others, and offers enough space to fit a week of travel clothes & casual wear without overstuffing it. It seems this packing cube was made to work with the Peak Design travel backpack, but it fits perfectly in most popular 35-40L travel backpacks and small rollaboard luggage. I especially like the separate compartment where I can store dirty clothes and detergent sheets in a sandwich bag in case I need to do laundry on an extended trip.The only negative point for the packing cube is while the rip-open feature is fun, the zippers do not close all the way, but a #1-size S-biner will fix that and keep them closed as they have a tendency to open if you pack it completely full.This is a great design, and the materials are top-notch. If you value high-quality luggage, you’ll want these packing cubes to go with them!

I could hold 12+ shirts during my last trip. Half of them were long sleeved. Great capacity and easy to compress. It's perfect to organize with other packing cubes.Very light and resistant. It seems well constructed and easy to wash.

The media could not be loaded. I looked and reviews for many compression cubes before trying these. I ordered two of medium more square ones, and one of the smaller rectangular ones. I have added both a video and photos. Amazon would only let me add one video so I chose to show you how it fits in a 60L duffle bag. The photos also show them in a hard sided 20" carry on wheeled case for scale. Just as others noted, the quick release to open zipper do come partially open on their own if too over-stuffed. I had to play around with them to see how to fold and how much would fit in it. My tendency was to over fill, rather than pack less. Somewhat of a learning curve on my part. I do think they are of high quality and zippers seem as though they will last, the company says lifetime warranty on them so that's a plus. I like that the edges are rather floppy around the zipper unlike the Thule cubes which are stiff and hold shape. The fabric almost feels like a tyvek fabric, super lightweight. In the gray one, I put 9 shirts and 3 pairs of pants (4 thin lightweight fabric and 5 cotton t-shirts, the pants were 1 pr yoga style stretchy and 2 lightweight quick dry style), The other white cube has: 1 pr jeans, 1 pr thick cotton sweatpants, 1 pr fleece pj bottoms, one Patagonia re-tool fleece jacket and 1 Patagonia down vest) and the smaller cube (rectangle one) has: 7 pr underwear, 7 pr ankle socks, 1 pr cotton crew sock, 1 bra and had room for a few more things) I didn't care for the loss of space around the internal framework of the wheeled luggage, the packed cubes ride above it, so there is air space around the frame inside the suitcase. I think I would have to get creative on using up that space. I think overall these are fantastic, and I have ordered one more small cube, depending on the bag/pack or suitcase, you may need to play around with configuration for your needs. I also would like to add that I put this gray medium and gray small cube packed as it is, inside the mail compartment of an Osprey Nebula backpack and they fit!

The media could not be loaded. I love Peak Design packing cubes. They are durable, work well, and made of top quality materials. This particular one is great and a very welcome addition to my digital nomad, constantly traveling lifestyle.

Absolute favorite cubes for packing. The back zipper for dirty items is amazing. They hold a ton of clothes. We used these for a 14 day trip and it held a ton of clothes. We replaced all of our other cubes and we've tried them all. Expensive but worth it.

This bag was extremely easy to use. I was skeptical at first that the compression functionality would actually work and that the zippers would hold. But it was extremely easy, and the zipper quality is amazing. The design is excellent and it fits in the Peak Designs travel backpack perfectly. The quality of the materials used is excellent. I ordered this bag as a test for me and a friend who has the same travel bag. I will be ordering more.

Very nice packing cubes. I like the easy open zippers and the separate pouch for dirty clothes. I dropped one star because I don’t think the compression is great.
