New silicone formulation with improved durability by being both stretchier and stonger than before. The firmness is now about 1.5A shore, but with a stretchier material it feels just as soft. I am moving to a little more expensive combination of silicone and additives but this should yield a sleeve that's much more durable. I AM NOW INCLUDING A 3 MONTH GUARENTEE FOR RELACEMENT. If it fails for any reason, provide a picture of the failure and I'll replace it at no cost. Please do not rip your sleeves up at day 89 to get a new one :). If they last 3 months, they will last you over a year.

The Middle Reliever (MR) is a platinum cured silicone "short sleeve" with and integrated girth band designed to improve sealing in your vacuum cup for extending/hanging/manual stretching. The girth band has an angled cut to fit behind the glans and sized for Total Man vacuum cups. This sleeve is short but thick, about 2.5x thicker than a standard sleeve. This allows application and removal to be done in seconds! Just apply lubrication to both the sleeve and your member to slide in or out (before or after the sleeve is attached to the cup. If you use this slide in method, there is no reason to stretch the sleeve which further enhances the durability and longevity; there is no reason this sleeve shouldn't last you 6 months to 1 year if using this application method. The material strength and thickness of the sleeve is over engineered for PE work, even heavy hanging and vibration. Please see the demonstration videos of how to use this sleeve as it is much different than standard sleeve methods. For users that tape the glans, it is recommended to apply the sleeve first via the slide in method, then clean/dry your glans, then apply tape and cup subsequently.
Sizing:
Each size option of the MR is designed to bridge 2 cup sizes to allow user growth and fit a wider range of members. The Total Man (TM) cups are the intended accompanying cup, but cups with similar depth should work (Epic, Phallosan are likely to work comfortably but are better if you use 1 size larger than typical use). The cheaper Chinese bell style cups will work only if using a cup 1 size larger than typical use. The sleeve is strong but stretchy so it will accomodate the cup size higher than it is listed as (e.g. 33mm sleeve will fit onto a 38mm cup). Sleeves are tapered at the bottom to improve sealing for exercises like fulcrum bends and bundled twists. If the sleeve is on the loose side, you can add a loose silicone ring or small cut section of sleeve under the cup to further improve sealing. The bottom of the sleeve can also be flipped up to double over and provide additional sealing.
"33mm Sleeve": Designed to fit cups in the 33-38mm range (Cups #2 and #3 from TM), 0.9"ID
"38mm Sleeve": Designed to fit cups in the 38-43mm range (Cups #3 and #4 from TM), 1.05"ID
"43mm Sleeve": Designed to fit cups in the 43-48mm range (Cups #4 and #5 from TM), 1.25"ID
I recommend using your current cup sizing to choose a sleeve size but also you can measure your stretched flaccid girth which should be 10-25% larger than the sleeve inner diameter for appropriate compression.
Material:
Platinum silicone (1.5A shore, new formulation as of April 2025)
Platinum cured silicone is the only true body safe silicone/elastomer variant which mitigates bacteria build up vs. the high volume, cheaper materials like PVC or other thermoplastic elastomers. For care, this pad can be cleaned with soap and water or rubbed down with isopropyl alcohol.

These sleeves are intended NOT TO BE STRETCHED in order to ensure longevity. See methods below for the lube and slide application method:

KNOWN UNKNOWS and WATCHOUTS:
There is no 1 sleeve sizing that fits everyone.
Internal Sleeve Thickness - If the sleeve is too thick, it may slide over your coronal ridge
Internal Sleeve Shape Not every glans is shaped equivalently. If problems arise from mismatch in sleeve shape, let me know
Use this only while either sitting or during light walking. The sleeve tapers to improve the sealing in the stretched state, but I'm certain it has limits.
I hope you enjoy this thing, but please reach out to me here or on reddit (u/6-12_Curveball) with any feedback, concerns, questions, or praise.
Middle Reliever - Short Sleeve
I strongly suggest to wash your sleeve daily with a mild soap and, if using Total Man cups, rinse out the valve daily as well (can force through soapy water by filling cup and adding pressure with your hand).
I do not suggest leaving the sleeve on the cup when not in use. Pt silicones are less susceptible to creep vs. LSR or TPE but they will demonstrate some creep and stretch/soften a small amount over time. If outer cup sleeve does stretch out and loses vacuum, just add a band on the outside (rubber band, other cut sleeve piece, etc).
Reviews
I live in Korea and I was willing to pay $25 for shipping to get this.
It holds tighter than I expected, unlike the Chinese sleeves, and the pressure doesn't leak.
I'd probably buy another 43mm sleeve next time.
I've used every vacuum cup and sleeve combination you can think of and never had anything this comfortable in my life. I can easily slide the vac cup off and on to go pee which is priceless in my opinion. There is no edema EVER and because of this new sleeve I actually enjoy all day extending and will likely be very consistent in the future with this product. I HIGHLY recommend anyone to invest in this cheap but very effective product. You will not regret it and your member will thank you!
This is hands down the best sleeve out on the market. The fact that you can slip it on and off in seconds makes ADS doable and not a tedious task. No need to tape your glans with this sleeve, and you can apply the vac cup with minimal or no pressure. Therefore, you no longer have to carry the pump with you at all times. This sleeve drastically minimizes the edema below the glans. For the comfort and efficacy of this product, it is greatly underpriced. Set an alarm to purchase this product!
Initially used the sleeve with the Chinese cup and struggled to keep suction but moving to the clear cups it was perfect, suction great and fit so much better over glans. The design is excellent as edema build up was hardly a thing if at all using this to just a normal sleeve and would highly recommend. Only downside is that a hole appeared where the ridge of the cup is on the sleeve & now water seeps through it after 3 months use of maybe 2-3 times a week. Wish it lasted longer but great item
Absolutely great, it reduced set up time by half. It also reduced the amount of edema under the glans. I would say it's better than using 2 sleeves and even taping if you use lube.
