I'm a Forester, and my field work covers timber operations all over the southeast US from East Texas all the way up to Eastern Virginia. I travel a TON. I've always wanted to get Frost River kit since I found out about them while I was living in MN/WI. This new job gave me a good reason to do so, and these five small Ionia cubes did not disappoint. I can fit a pair of pants, a shirt, socks and boxers in each with room to spare. easily enough room to toss in a set of insulating underwear. I combined these with a Carry-on sized ImOut Duffel. the combo works perfectly. goes right behind the seat in my work truck and now due to the durability I just keep them permanently staged. drop of a hat I can be out in the field for a week or more, and these little cubes made it a total easy button. they even fold up nice too when you're not using them. If you're getting any of the frost river luggage (I suggest you do so), these are perfect for quick and efficient organization.
