The two Orvis UK listings are guided bass-on-the-fly sessions, not lures, but they’re the strongest matches if your “16th” query was about bass fishing around light tackle or presentation in tidal water.
If you meant 1/16 oz specifically, the Invasion jigs are the most directly relevant product in this set.
Technique notes
For the 1/16 oz weedless jigs, fish them slowly and keep contact with the bottom or cover.
Use short hops, pauses, and a steady crawl when fish are pressured or the water is calm.
In tidal bass water, the fly sessions point to reading tide movement and presenting along shorelines and wading lanes rather than fishing deep.
When to switch
Switch to a heavier jig or a faster-sinking presentation if wind, current, or depth makes 1/16 oz too light.
Switch to a more aggressive lure if fish are chasing but not committing to a subtle weedless jig.
If you want gear rather than instruction, ignore the guide-trip listings and focus on the Invasion jig pack.
