Verified ownerI wanted a visor on my head covering for summer outdoor swimming at the beach, so when I founf this Nammu product, I was thrilled. The hat is well made and fits with adjustable ties for more secure feeling. The visor is just the right size to provide shade and not be in the way while relaxing on the sand or swimming. I look forward to testing my theory in a month or so when beach temperatures arrive.
Verified ownerGreat option for bringing on cap on vacation and getting two looks! I love the reversible option! Wear it with a classic black swimsuit, or any kind of pattern. It's as wonderful as the Nammu classic, with a double feature!
Verified ownerI wore this Nammy classic during an R&R getaway. The indoor pool and Hot tub were awaiting and I couldn't wait. But I was feeling self-conscious since loosing so much of my hair, so I bought swim caps from Nammu. I found them to be comfortable and easy to wear. They kept my head warm and dried quickly!
I totally recommend the Nammu Classic in a fun color.
Verified ownerMy Nammu swimming hat helped protect my scalp and neck from the tropical sun during many hours of snorkeling during a recent vacation in Curacao. It also kept my hair dry, and it's a lot cuter than a typical swim cap.
Verified ownerNice build quality but the XL is not nearly large enough. Is it really EXTRA large? Delivery was slower than hoped for.
