My Henderson Aqua Lock suit just arrived off of back-order last weekend and I tried it for the first time today.
I live in Hawaii and do a lot of photography, usually diving in a lined lycra suit with a hood and vest.
I recently bought some new booties and prefer thin gloves so I only purchased the hood plus 3mm suit.
First impressions were great - as mentioned above, it was easy to put on, take off, very comfortable and stretchy.
I've never tried any other semi-dry suits so I can't compare, but it kept me nice and warm for my 65 min dive today.
