Okay, so I finally got my hands on this Arena swim parka after reading mixed reviews. Here's my take:

First off, it's WARM. Like, 'I-forgot-it's-winter' warm. The fleece lining feels like a hug, and the waterproof fabric actually works (tested in light rain).

BUT - sizing is weird. I'm usually medium in everything, but had to exchange for large. The arms felt fine, but the torso was oddly snug? Can't imagine zipping up with a towel like some reviews mentioned.

The pockets are awesome though! Two big front ones + hand warmers + inner pockets = perfect for phone, keys, goggles. My swim bag stays in the locker now.

Quality seems decent except...the zipper feels flimsy? Heard horror stories about breakage so I'm babying it. For $100+, that shouldn't be necessary.

Final verdict: Great if you size up and don't mind babying the zipper. Would I buy again? Maybe on sale.
