    • great product
Color: Black/Black Size: Medium
this impact vest is great, it does the job of making me safe and afloat without impacting my mobility practicing watersport . this is made of quality material and you can appreciate it will last on the long run. Recommend that you verify the size ahead of purchasing as it can fit a little small.

    • tight fit, works but consider sizing up.
Color: Black/Black Size: Large Regular
We ordered a size large men and debated an XL. It's a snug fit but loosens and forms as it's worn and gets wet. Not sure if we would have compared the XL if that would have been a better fit, but we are pleased with this jacket.

    • Protects the chest like a champ!
Color: Black/Black Size: Large Regular
This has saved me from numerous hard falls and from getting the wind knocked out of me. Love it for learning spins and inverts on a wakeboard. The design is pretty sweet and very low profile, no eccentric color design to turn heads but looks bougie. The quality is okay, I've only used it a handful of times and the fabric is starting to show signs of wear and rubbing which is expected, but will be put to the test as time goes on. Very strong product overall especially for the price. IMPORTANT: This is an impact vest not a life vest, it provides very little floatation, if you need to stay afloat and keep your head above the water this may not be for you. It's not a problem for wakeboarding where I always have a boat and people around, but for jetskiing this may be a concern. ... show more

Don't go out into hurricane swell without some flotation and a great leash. You might not come back.

    • The jackets looks awesome!
Color: Black/Black Size: Medium
They have a very sporty look to them. They fit so well and are really easy to use. The zipper is reversable - although, I wouldn't use the jacket inside out because of the inside tag that is ironed onto the jacket. However, it is nice to know that you have the option of flipping the jacket inside out for any event. Other reviews have mentioned the jacket stretching out - I have yet to use these and will update this review once I do. I purchased to use on our jetski. We can't wait to wear them out! We have sent pictures to all of our friends and they're all interested in purchasing as well. I know they're pricey, but to me, very worth it. If my review was helpful, please let me know! ... show more

    • Absolutely no way to communicate
Color: Black/Black Size: Medium
This item was purchased as a Christmas gift. The size was too large so I exchanged it. I returned the item December 26th, 2022 via the UPS Store. Everything was in the original packaging and I used the email with the scanning barcode. I have now been charged again for the amount that I was originally refunded when the item was exchanged. I have not been able to contact anyone about this. I am extremely disappointed as the item was expensive. Not happy with this purchase. ... show more
