*These stringers are made of an ultra light Rayon/Spandex blend with impossibly thin straps. Do not yank on the straps aggressively or they will snap. There is no way around this in order to achieve the "thin" strap look. We’ve been dancing around this for awhile but we gotta say it. It’s time to free the nipple. Our new Ultra Pump Stringers represent the final form of retro stringers. Unlimited freedom and comfort. You don’t even need to lift a weight before you set that Hunk Alarm off. Alarms are ringing, children are screaming. What’s holding that up? Is it magic? it is It’s ULTRA PUMP magic These stringers are for the hardcore. There are literally dozens of us clamoring for the old school magic to make a triumphant return. Ultra Pump stringers are made of a Rayon / Spandex blend that was carefully selected to ensure that the stringer had just the right amount of fabric droop to let the material hang off of those mammoth traps. The fit is similar to the tanks and stringers we've released before in terms of length and fit. The main difference is the strap and how the chest space contours to accent your mammoth chest. Material: Rayon/SpandexIt is recommended you go with your standard sizing.
