Look nice and keep your wrist dry.
I've ordered two sets of these now and love them. I was having problems with bands that didn't allow air to the skin and these have solved my problem. They are well made, easy to switch out, and the colors are nice.

Colors are great, and the bands are extremely comfortable allowing air to cool the arm.
I really like these bands, and they are easy to change so I can be color coordinated if I want. Price was great, and I'll see about durability as time goes on. I've had mine for several months, and so far I love them!

Works & inexpensive
Fitt my Charge 6 beautifully and snapped on easily. There are other ones available that are three times more expensive but no better looking and probably no more durable....

Better than the band that came with the watch.
Over the years I’ve been using Fitbit, I’ve found their OEM bands suck so I always buy bands off Amazon to have on hand. They usually last longer than the originals. When my charge 6 arrived. I had the backup bands ready to go. I didn’t like the original bands at all, so I didn’t even bother putting it on. Switched out the band with one of these and it’s great. It’s actually my favorite after market band for Fitbit I’ve ever used, very comfortable.

I love these bands - the turquoise really pops
These bands have proven to be durable and don't irritate my skin because of the breathable design. They aren't flimsy, they are just the right thickness in my opinion. In this batch I love look of the purple and the turquoise. The peach is fine, and I've never been a fan of burgundy. This can fit my 9 year old and it can fit me too.

Must buy
Definitely worth buying again. You can get a Durable product at half the price of buying from Whoop.

Price reflects the product
Aesthetics are good. The slide clasp had to be tightened with a vice in order to not continuously slip off. After one week of wear I had a tear on the fabric.

Esta correa deportiva de nylon Surundo para Whoop 4.0 me sorprendió gratamente. La correa es ligera, transpirable y muy cómoda para usar todo el día, incluso durante el ejercicio. El ajuste es preciso y se mantiene firme. La carcasa protectora incluida ofrece muy buena protección sin agregar volumen, y los materiales se sienten resistentes y de alta calidad. Una correa de reemplazo que mejora tanto la comodidad como el estilo. Muy recomendada.

Loved that they are easy to clip onto the bracelet but was very disappointed that they discoloured so quickly. I have been wearing the peach-coloured one for approximately three weeks and it looks dirty and dingy. Oh well! At least it help clear-up the massive burn from the original bracelet!
