✅ Quality – These glans and shaft sleeves are the stretchy, thick, rubbery kind. They’re made with high quality silicone rubber and are made to last (just don’t test the stretchiness by pulling on it excessively). The quality materials ensure a good grip along the shaft and glans, allowing you to effectively hang with heavier weights when using your UGM Ligament Traction Trainer. ✅ Sizing - If you have the SMALL or MEDIUM glans cup set for the UGM Ligament Traction Trainer, you’ll want to order the size medium shaft sleeve (3.1 inches). If you have the LARGE glans cup set for the UGM LTT, you’ll want to order the large shaft sleeve (4 inches). Each set comes with 1 glans sleeve and 1 shaft sleeve. ✅ Cleaning and Care - Wash all parts with warm water and soap after each use. Leave out to dry before storing away. These shaft and glans sleeves are made with high quality silicone rubber and are made to last. They’re thick and stretchy and they easily maintain the suction and hold necessary during long, heavy hanging sessions. They’re typically used with the UGM Ligament Traction Trainer (LTT), but they can also be utilized and fitted to other traction devices that use the same suction glans cover. Each set comes with 1 glans sleeve and 1 shaft sleeve (Medium or Large). If you have the Small or Medium sized LTT, you should get the Medium sized sleeve. If you have the Large sized LTT, get the size Large to go with your set.
