Title : Could be stronger
Comment : This was the second time purchasing as my son busted the one that came with his planetbox. Currently the section on the end has a hole in it and all the liquid has leaked out. On the upside they do keep the lunchbox nice and cool, just a shame they bust easily.

Title : Icepack
Comment : I purchased this with a Planetbox Rover and slimline insulated bag. It is just the right size to use in the slimline as it is very flat and other icepacks tend to make the pack much bulkier. It keeps the lunch kit cool enough to make it until the afternoon but wouldn't last much longer - so if you're needing your kit to stay cooler for an extended period I would suggest a bulkier ice-brick or refrigeration. The sleeve is easy to remove to wash and I feel good about not having an icepack full of toxic goop.

Title : Good product keeps product cold & washable cover is a bonus
Comment : Purchased to go with Planetbox Launch slimline bag for partners work lunch. The do stay cold for a long time and work be great for kids I think. It is a little fiddly, so we ended up swapping to a bigger bag and using a Techni ice pack & this was easier for us. I did really like the washable cover that came with it though.

Title : Fantastic
Comment : This is a wonderful addition to my son's planetbox. It easily slots into place in the cooler bag and I don't have to worry about his food warming up during the day. It keeps everything nice and cool. I also really appreciate the thought that went into the design. Having boys, I am always worried that something like this will burst and be ruined but knowing that the ice pack is divided into small sections sets my mind at ease. If one bursts, it can still be used and so far it has held up very well with no damage.

Title : A must for the planet box lunch box
Comment : I damaged my first planet box lunch bags due to squeezing in icepacks that were too big. Due to the thin size of these ice sleeves they fit perfectly in the lunch bag so are a must for anyone who owns a planet box. However one of mine had 3 bubbles pop after 2 weeks which was disappointing particularly the cost, so I can't give them 5 stars

Title : Pretty good
Comment : I bought this to fit inside the Shuttle bag, which is a bit of a squeeze but thanks to its flexibility it can be done. My four year old does have trouble getting his PlanetBox back inside the bag on his own with the ice pack, though.

Title : Must have!
Comment : The cold kits are definitely a must have item for the planetbox. We have been through a few summers in Brisbane, and the kids have found their school lunch stays cool enough with these.

Title : Great accessory
Comment : We live in Western Australia so this is essential with the planet box for us. You could always just buy one similar if you wanted to save a few dollars but I like that this one matches and is the perfect size for the pocket. Keeps the lunchbox good and cold.

Title : Disappointing.. maybe just bad luck.
Comment : I purchased one of these for my sons planet box. Unfortunately within two days it had somehow popped, leaving his lunch box and contents wet. Maybe we received a faulty ice pack.. or maybe my son was too rough with his bag.. I'm not sure. But I can't give the 5 stars I wanted to because of our experience.

Title : Nice and useful ice pack!
Comment : Been using this for daughter's Planetbox Shuttle about 7 months. It keeps her lunch fresh even after school finishes since she usually didn't get to finish it (she is a slow eater!) and wants to eat the remaining during pick-up. Also, as other reviewers said it's very easy to clean!

Title : What's cooler than cool? Ice COOOOLD
Comment : We use these every day in our kiddos planetbox sleeves to keep their lunch cool. They're small and slim and give just the right lil' extra cool so that their lunch isn't gross come break time. Stood test of time and one we've had has been used every school day for a year and still looks great. You can remove the cover and wash it if you're not lazy like me ;)
