The medium was the perfect size, zipper is tight and fairly easy to use. Just go slow around the corners. The water resistant material is amazing and I can fit a few outfits in the medium cube. Didn't think I need another cube but this was very useful and easy to push the air out once almost zipped.

Keeps the elements, dirt, dust, and grime out to keep your conents safe & clean. While not submersible, it keeps your contents clean & dry from melting snow, falling rain, splashing mud, paddle spray, and fish flopping around the boat. As a size reference, the medium fits a six pack of cans with space left on the end. The zippers are shielded and have nothing to snag on. The material cleans easy with just a wet rag and returns to looking like new. One size is not enough; you'll want multiples of each size for packing flexibility while keeping your things safe & dry regardless of where your adventure takes you!

these fit great in a backpack, layering up and keeping my need for a pack cover low. Easy to see what's inside, grab out of the top of the pack, and actually use (i.e. pack inside). The only thing I wouldn't use these for is packing a bag/quilt or tent, just based on how I store those.

I have taken this packing cube on a couple of trips, some in the city and some in the back country. I have used it as a toiletry bag both times and it has worked like a charm. I like the materials Sea to Summit chose to construct the bag and I feel as though it will last me a long time.This bag has earned it's place in my competitive gear list!
Received the medium cube last month just in time to take on a ski trip. This is a great little travel case. I used it to store a bunch of the small misc. items I was carrying in my luggage. Then used it to carry some clean items in the car for apres ski. Does exactly what it needs to without being too flimsy or heavy.Pros:Very light compared to other cubes but still plenty durableMaintains structure while still being flexible enough to shove into a corner of the bagThe slightly clear top helps you keep track of which cube you put things in (if you have more than one)It looks cool!Cons:The zipper definitely requires two hands to open/close, but this helps with the water resistance
I just received this packing cube in the mail, and I honestly hadn't thought I needed one of these until I had them in my hands. This cube is lightweight, functional, and the material can be compact. This will be on a lot of my upcoming travels for canoeing and kayaking. I wish I had bought one of these before my trip to Wyoming last year. Very excited.
There are so many packing cube out in the market now, I didn't think I'd need this from Sea 2 Summit... oh boy was I wrong. I tried the Medium sized one just to see how it works....Not gonna lie initially I was a little skeptical when I tried the S2S packing cube... for size I'm a medium unisex T or L in Women's, M to L leggings. I can fit about 3 tees with 2 leggings in the medium sized one comfortably and if I zip almost all the way, the bag was able to let me push out the air before zipping thru the last 1/8 inch. The bag itself is water resistant which would be great for any outdoor activities. My current favorite use is to pack a day worth of stuff to go with me in my backpack when I travel so in the event the luggage decides to go on an adventure, I'll have a ...

Also have packed spare change of clothes for car camping and it's worked out well. The zipper is a little tricky to open initially when the bag is empty but was easy to use once the bag is fitted with clothes. I just love how it can almost be "air tight" to push out the air and that it has a clear top to see thru what I packed. It's super light and this will be my go-to packing cube from now on. Thanks so much for making amazing, quality product S2S!
It feels well made and gives you confidence that it will last a long time. The transparent material is a thoughtful design that I like. It's easy to pack and the walls collapse well so that it can conform to a less full load and fit within a larger pack. So far no complaints.
This cube was a great addition as we were outfitting our truck camper for long weekends and extended trips. The size was perfect as a toiletry bag, but we would also use it for storing tech gear (cords, etc) and other miscellaneous items. The flexible shape means you can stuff it into another bag/bin with ease, and being able to see through it makes it quick to confirm you are in the right spot, especially when you have more than one of the same size.
Thoroughly enjoy that once you’ve packed everything into these little cubes it’s possible to get as much air out of them as possible before zipping it up. Close to a vacuum sealing effect just not quite there.I’ve bought every size so far and would recommend medium and above if you’re considering packing actually outfits. The large is big enough to fit an easy 2-3 shirts with a pair of shorts.
