There's been a lot of talk and a few articles lately about the Storm cases being much lighter than the respective Pelican cases. We checked specs in the catalogs and the published shipping weights and we could not come to a conclusion. So we decided to do a side by side test. We already stocked the Pelican 1624 (1620 with the Padded Divider Set) and we ordered the Storm 2750 Case with the Padded Divider Set.
Here's what we found:
Pelican 1620 Case Empty: 20 lbs.
Storm 2750 Case Empty: 18.5 lbs
Pelican 1624 Case (1620 with Padded Divider Set): 23.5 lbs
Storm 2750 Case with Padded Divider Set: 25 lbs.
The Pelican Case with the Padded Divider set is actually 1.5 lbs less than the Storm Case. In testing other Pelican vs Storm cases the same is holding true, the empty weight of the Storm Case is generally about one pound less than the Pelican. But the weight with the Padded Divider Set is actually higher with the Storm Case.
One final comment, these are both great cases and I can easily recommend that you use either one. I like the locking latches and the wheels on the Storm Cases. I like the Padded Diver set better on the Pelican cases. The Pelican cases also offer more protection on the bottom of the case. So in the end the choice come down to a personal decision as to which case works for you. But as you can see the actual weight of the cases is not a realistic decision factor.
