Overall, the Mares Trilastic Rashguard Long Sleeves is a great product, but it’s a bit pricey. The material is very comfortable, and the long sleeves provide great protection. However, I wish it came with a more secure zipper.

I recently wore the Mares Trilastic Rashguard during a water sports competition and was blown away by its performance.

Is the Mares Trilastic Rashguard suitable for scuba diving?
Imran Hanafiah –
Thank you for reaching out to us, Lee Chee Keong. We’re glad you’re interested in our Mares Trilastic Rashguard.

The rashguard provides excellent skin protection and UV protection, making it ideal for underwater activities. Many of our customers have successfully used the rashguard during their scuba diving adventures. However, please note that it’s best used as an undersuit or a layer over your wetsuit, not as a primary wetsuit.

I recently purchased the Mares Trilastic Rashguard as a gift for my cousin, and they absolutely loved it. The quality is top-notch, and the UPF 50+ protection is a must-have for water sports enthusiasts. I was impressed by the durability of the product, and my cousin has worn it multiple times already without any issues. The only thing that prevented me from giving it a full 5 stars is that the ‘DC staff identification’ feature seems to be more of a marketing gimmick, as my cousin wasn’t exactly ‘identified’ as a staff member when wearing it.
Xiaoming Wong –
I have been using the Mares Trilastic Rashguard Long Sleeves for Freediving and I have to say it’s one of the best rashguards I’ve ever worn. It’s very comfortable, and the UPF 50+ protection is fantastic. I wish it came in more colors!
Ling Chan –
I recently used the Mares Trilastic Rashguard Long Sleeves for snorkeling and was impressed with its durability and comfort. The material is soft and breathable, and the long sleeves provided great protection from the sun and the water. I was a bit concerned about the price, but it seems to be worth it considering the quality and performance.
Sharmini Kandasamy –
What is the difference between the Mares Trilastic Rashguard Long Sleeves and the regular Trilastic Rashguard?
Junhao Lo –
Thank you for asking, Sharmini. The main difference between the Mares Trilastic Rashguard Long Sleeves and the regular Trilastic Rashguard is the length of the sleeves. As the name suggests, the Long Sleeves version has longer sleeves to provide extra protection from the sun. This makes it an ideal choice for outdoor activities that involve prolonged exposure to the sun. Both versions, however, offer excellent sun protection with a UPF50+ rating and are suitable for underwater activities.
Melissa Koh –
I used the Mares Trilastic Rashguard Long Sleeves during a recent diving trip and it performed amazingly well. The material is very comfortable, and the UPF 50+ protection kept me safe from the harsh sun. I highly recommend it to anyone looking for a great rashguard.
Soo Hii Tan –
Does the Mares Trilastic Rashguard Long Sleeves have a snug fit?
Imran Hanafiah –
Thank you for reaching out and sharing your question about the Mares Trilastic Rashguard Long Sleeves DC UPF50+. The rashguard is designed to be true to size, but we find that it can be a bit more flexible and accommodating due to the stretchy fabric. This means that it can fit snugly on some body types while still allowing for ease of movement. If you’re concerned about the fit, I recommend checking the size chart and considering your personal preference for a snug or looser fit. Would you like any further guidance or clarification on sizing?
