Abstract
A fecal canister for use in a space application has a canister body extending from an inlet end toward a remote end. Hooks are aligned along an inner surface of the canister from the inlet end towards the remote end. In embodiments, a compaction lid, or a storage bag catch on the hooks to maintain a compacted position.
