Strolling the beach or a market, when the sun is out the last thing you want is a heavy purse to tote. Keep cool and lighten your load - just tuck your essentials in a TuckTop and keep your hands free.
This is me, hopping rocks on Vancouver Island. It was a beautiful, perfect day with my husband and daughter and there was sooo much to observe and discover in the tidal pools.
Did I worry about stuff I had left on the beach? Nope - because my wallet and cash were tucked in my TuckTop. Did I think my phone would drop? Nope again - it was snug horizontally tucked in the lower left pocket. Did I have my chapstick with me? Yes. Even suncreen (a very small tube).
If I had thought ahead, which I hadn't, I could even have brought a small magnifier for up close sea aminome observation. Life is a lot of fun with free hands ;)
