Geared toward camping/ backpacking, these great compression sacks are wonderful space savers in baby’s checked bag for bulky items such as baby blankets, sweaters, and jackets. I also find the x-small size very useful for keeping my own set of spare clothes, as well as spare clothes for baby, compact in our carry-on to save space.
The Granite Gear Round Rock Solid Compression Sack product description: “We designed these stuff sacks to easily compress lofty items such as sleeping bags and clothing to a nearly rock solid state. The unique design evenly distributes the stress of compression and prevents bulging.”
As I continue to streamline my packing to reduce the number of checked bags we bring with us, even on longer trips, I am finding that it is easier to travel lighter by combining my own things with baby’s suitcase into just one checked back. The sacks also come in a variety of sizes, and it often helps to have a couple in different sizes (E.g. one for blankets, and one for dirty laundry). Compression sacks can be a great way to save on space to accomplish this by reducing the bulk of items, and dirty laundry too!

I have never seen compression sacks in person and was looking into getting one off Amazon. What size do you recommend if I plan on using one to pack about 18 cloth diapers? I have a mix of AIOs, AI2s and pockets. Btw, I am so glad I found your site. Lots of helpful tips!
Shereen, I am glad to hear you have found the site to be helpful! I am currently traveling with about 30 pocket diapers and 40 inserts. I use an XL size compression sack for these plus about 40 cloth wipes. For the mix of 18 diapers you mentioned, you can probably can getaway with a large size, although you might consider getting an XL anyway, as the extra space won’t hurt once compressed just in case you need more space.
