Can I really swim in them?

I just bought a pair of hann u link (won't let me post the whole name for some reason) tri shorts on eBay. The listing said "Antibacterial Quickdry Pad", but I just got them and was surprised how big and fleecy the pad seems. Also, it has two little side pockets.

Does anyone have experience with this brand? Does the pad really dry fast and not feel weird? Do the pockets create drag in the water?

I just wanted to ask for feedback before taking them for a dip! I was determined to swim in my bathing suit and just put bike shorts over it until I tried it, hence the purchase of actual tri shorts!

Thanks in advance!
