ジップアップ拘束具

Wasn't sure the ergonomic cut would actually fit right, but the adjustment system lets me dial in the tightness precisely. The PU sleeve keeps my arms and shoulders locked in place without pinching. Solid build, exactly what I was after.

Wasn't sure how the adjustable straps would hold up, but they lock in tight and stay put through a whole session. The PU shell is firm enough for real restriction yet the ergonomic shape doesn't dig into my shoulders. Genuinely impressed with how precise the fit is.

The PU material feels sturdier than I expected and doesn't crease when the arms are pulled back. The adjustable straps let me dial in the tightness precisely, and the ergonomic cut keeps the shoulders stable without pinching.
