The Shell Shock will fit in an XL Stash, but works better in one with a spring, like the XL FutoStash for instance - as the spring makes up for the size difference.
I'm storing mine though in an Dynavap XL tube (shown below), which fits the Shell Shock pretty well. However, it unfortunately looks like these are no longer offered by Dynavap (not sure why).
You may be able to locate one from another seller, or if you’re in the US and want to DM me your address, I'd be happy to ship a lightly used extra one I have in an envelope with a few stamps on it. Tis' the season!
