Masao,
As mentioned above the Extension Sleeve (ES) is the sheath only version of the Innerwear. The base band on the regular Stealth is 2 cm so the ES gets the extra sheath length so that the overall sizing remains the same.
Sounds like the ES would be more suitable for your anatomy. Although it is made to order and requires more time the cost remains the same.
Regarding price… first and foremost we will always deliver good value.
all the best to you!
