Second poster is right, there are no gauntlet that use as Daedric Artifact.
The following "clothes": * Ebony Mail * Masque of Clavicus Vile (if you chose to give up weapon) * Savior's Hide (if you chose to respect Daedric Lord, rather than saving the release wolf) * Ring of Hircine (if you chose to saving the release wolf rather than respect Daedric Lord) * Ring of Namira
The following "weapons": * The Rueful Axe (if you chose to kill dog) * Volendrung * Mehrunes' Razor (if you chose to obey Daedric Lord) * Ebony Blade * Dawnbreaker * Mace of Molag Bal * Sanguine Rose * Wabbajack (not really weapon, but it made people hostile if you casted) * Skull of Corruption (if you chose to ignored him at last minute, after the barrier is down)
The following "misc": * Azura Star (if you chose to aiding Daedric Lord) * Black Star (if you chose to aiding guy down in the Hold) * Oghma Infinium * Skeleton Key * Spellbreaker
That's it - no Gauntlets or boots. --- I used to be hearing person like you, until I took the fever in my ears. ~FredCat
