Long, long ago there was a similar pair of latex swim trunks that offered torso-conforming coverage in a suit comfortable for long term wear. Alas the company making them disappeared, taking with them that great suit.

Hydroglove to the rescue! This new suit has all the strengths of the old one. Gently confining without emasculating, the briefs felt like they belonged as soon as I pulled them in place.

User's suggestion. Remember Mike Nelson in Sea Hunt, and his short cutoff trunks? Once you have these very high-waisted "briefs" in place, pull them back down (from the top) without disturbing the crotch. Then fold the top edge back up until it's level with the crotch. Finally, grab the briefs at the folded edge and tug them back in place. Voila! Some very tough looking -- and imminently comfortable -- low-rise rubber swim or posing trunks!
