The HUNKYJUNK NANO NIPS are a great for “just the tip”. 

These mini-suckers are made of Liquid Platinum Silicone, so they won't crack, crush or lose color. Firm enough for the right amount of “pull”, but rubbery-soft to really seal, with a wide, flat flange around the base to help them stay on and feel like they are part of you. Carry-case included so they don’t get lost in your piles of gear.

Pro Tip: Before squeezing the air out of the suckers, wet the rim with spit, waterbased lube, or waxy lip balm — you’ll get a stronger seal… hairy chest or smooth.
