A new wetsuit should feel performance-snug on land. Once you start swimming, it will settle onto your body and feel more natural after a few uses.
The suit should feel tight on land because it will relax and settle once you are in the water.
Putting on a wetsuit while wet or sweaty makes fitting much harder and usually leads to a poor setup.
Brand-new suits loosen up and become more flexible after several uses, so allow a short break-in period.
The suit is not a dry suit, so some water will enter. If you experience excessive sloshing, the suit may be too big and could require a size exchange.
If the suit feels tight while swimming, try opening the neck slightly to allow a little water in.
New suits become more flexible after a few swims, so give the fit a little time before making a final call.
