  • 10/20/2018 Love this cap!

    5 Review Stars By Valorie

    Where has this swim cap been all my life? I was a little hesitant to try this, because it’s so much more than a silicone or latex cap, but I’m glad I went for it. Goes on easily - no more having to pull my hair up and then struggle to get the cap over it. Stays on perfectly. I saw some other reviews saying it was too tight; I do not find it so. I hardly know I have it on. Love it!

    I swim laps 3-4 times per week and have been wearing this for about 2 weeks, so I can’t comment on the longevity. But I already have plans to add it to my Christmas wish list so I have a backup! ??

    5 Review Stars By Maria M.

    I got this cap for my 14-year-old daughter who has really thick, shoulder length hair.  Other caps pulled her hair, or didn't stay on.  This is perfect!  All her hair fits, it doesn't pull her hair, and it doesn't slide off while she is swimming.  It is true that it is not waterproof, but she is a competition swimmer, and the point was not to keep her hair dry, but to keep it out of the way while she is racing.  LOVE IT!

    2 Review Stars By longhairedwouldbeswimmer

    Had high hopes for this.  I have long colored hair. I'm a very active mid40s starting to plan some alternatives to my high impact activities. I enjoy swimming outside during the summer but limit how much I do since I hate to get my colored hair impacted by the pool water and sun.  Ideally, would like to be able to swim indoors during the colder months for great low impact exercise, but not being able to keep my hair dry is a major detractor.   Bought this with high hopes. Mine is black and grey. No size was indicated.  Only seems to come in one size, yet inside the cap it indicates that it is an "M".  The cap is painfully tight.  It has a nice snug design and material that does seem to avoid the hair damage that happens with other materials.  I called swimoutlet back about getting a larger one, but they do not have one.  No one else advertises having them in "L".  The material appears to keep the hair from getting soaked, but hair does still get damp.  Would love to get a solution that fits and works.

    Got this for my 10 year old.  It was too small to cover all her hair, which is not that much.

    I love the design, but its a little snug...making it hard to get on.
    Once you get it on, it is very comfortable.

  • 6/28/2011 No More Hair Ties

    4 Review Stars By SharkBait

    This cap is all it says...easy on, keeps hair secure w/o ripping, no more hair tiesneeded, nice colors, doesn't squeeze my head too tight.  Great video on YouTube.  I have hair past my shoulders and swim daily in the ocean and it works like a dream. The only reason I give it 4 stars is due to the price (shouldn't cost that much) and the pink/purple bleeds upon 1st use.  FYI: the blueberry is most def a purple not blue.

  • 1/25/2017 not what I expected

    1 Review Stars By Stacy

    Was new to ever having a swim cap .Thought it was  something to keep your hair dry. I was surprised it did  not. I went and looked at my enclosed  shipping paperwork to see how to return and was again surprised to see it was not returnable because it didn't have the tags. I was very disappointed at your return policy and will not be shopping with you again

    Don' know what you wnt here

  • 7/17/2015 Easy to use, very comfortable.

    5 Review Stars By Lucille Tse

    This cap is so comfortable! I am Asian with a flatter head and it stays on where I put it. It does not give me a head ache. It is so easy to put on and remove.

    I do light and moderate swimming laps. I have never had to readjust this cap once I put it on. I highly recommend this cap.
