Onomatopoeia for taking off a helmet


What I'm looking for is the Japanese equivalent of the sound of taking off a
helmet, particularly a full-head helmet, like a racing helmet or a motorcycle
helmet. For the life of me, I can't find any manga panels to reference. The
closest I've found is スッ but I think that only applies to fabric, like shirts
or jackets.




スッ can be used if the helmet is taken off smoothly, without friction. サッ may
be ok too.

スポッ is better if there is some momentum when taking off the helmet. The word
describes something fits in tightly, and for the reverse direction (putting
out).

  * 大根がすぽっと抜ける
  * 帽子をすぽっとかぶる ([source](http://sura-sura.com/archives/3086.html))
