A strange feeling, at night I thought that they would let water through, so I tightened it. Yes, they advertise that it is not necessary to tighten the twist in the face, but I decided it would still be more reliable. I tightened it until my eyes popped into glasses, thought about it and loosened it a little. First dive, wow, we have something to see in the pool. Well, it's disgusting here. In short, watch the fire in front. The side view is not yet clear, there are questions. Chased today with one, I couldn’t understand how he had already lagged behind or overtaken))) Now it's time to relax the puffs and believe in advertising, it started to flow and all the training did not go, the points were spent. The second chance is better, loosened the elastic bands like ok. In short, I'm getting used to it, let's see how the next swims will go...
