If you're following GUE gas guidelines these should breathe fine at any depth thanks the helium.
Good luck,

Not my experience Pat - but there you go.. They work - but the WoB is a bit higher than I like in the 21/35 range.. never been deeper on them. That said - I used to find the Apecs a bit stiff to breath after the poseidons I used to have - so I guess you could get used to them.
