Chest / Bust — Wrap the tape around the fullest part of your chest, keeping it parallel to the floor. Bring the tape under your armpits and across your shoulder blades. Don't pull too tight.
Waist — Find the narrowest part of your torso, usually just above your belly button. Stand naturally — don't hold your breath or pull in your stomach.
Hips — Stand with feet together. Wrap the tape around the fullest part of your hips and seat, parallel to the floor — usually about 8–9 inches below your natural waist.

Fit Tips for Diving

🇺🇸

Used to US sizing? Size up if between sizes

Our sizing runs slightly small for standard US size charts — we recommend staying true to size or sizing up if you're between sizes. We recommend a snug fit since polyester stretches out in the water.
🇪🇺

Used to EU sizing? Size down if between sizes

Our sizing runs slightly big for standard EU size charts — we recommend staying true to size or sizing down if you're between sizes. We recommend a snug fit since polyester stretches out in the water.
🤿

Stays put under your BCD

Our rash guards are designed to stay in place through multiple dives. Size to your chest for the best fit — the rash guard should feel snug enough to not ride up under your BCD, but comfortable enough to move freely underwater.
🩱

Layering under a wetsuit

A rash guard worn under a wetsuit reduces friction and helps the wetsuit glide on more easily. For layering, size true to your chest measurement — a close-fitting rash guard works best as a base layer under neoprene.
🔀

Which Measurement to Prioritise

If your chest, waist, and hip measurements suggest different sizes, always prioritise your chest measurement for a rash guard — it determines the overall fit across the shoulders, arms, and torso. The chart is the same wherever you order, and most people should simply take the size it gives them. The selector above only changes the call when you land between two sizes — set it to the sizing you normally buy.

everything i ordered fits so well! If you follow the size guide and take some measurements on your body you will find your perfect fit! The material feels very good - i think i can also wear it for other sports.
I ordered the pink Rashguard and it looks so sweet also with the bikini and the Leggins! Can't wait to wear it underwater.
Also the custumer support ist very good!
The fact that it supports a coral project makes me even more happier, thank you so much!

Hi Theresa, thank you so much for sharing this lovely review! I'm thrilled the rash guard fits perfectly, feels comfortable, and looks great with your bikini and leggings. I hope you love wearing it underwater and for other sports too! It means a lot that you appreciate our customer support and coral donation. Happy diving!

Gorgeous and Comfortable rash guard !

Gorgeous and very comfortable rash guard (bought the long sleeve top and leggings). Received many compliments on the outfit. Looks and feels great underwater while scuba diving. Looks great after several dives and a wash. The boyfriend is now interested in changing out of plain black rash guards into Dive Compass colorful men's swim trunks!

Hi Carla, I'm so excited to hear you love the rash guard and that it looks great both underwater and after being washed! Thanks so much for sharing your experience and for the kind words. I'm glad it’s inspiring your boyfriend too! Happy diving!

This was my first order with Dive Compass, and I'm thrilled! I bought this rash guard and the matching leggings for an upcoming trip to the Philippines…hopefully good luck for whale shark sightings!

I was genuinely impressed with the quality of this top. It fit great and felt sturdier than similar items I've bought from other brands. I can't wait to put it to the test in the water!

Hi Cheryl, I'm so happy to hear you're thrilled with your first order! Wishing you the best of luck with the whale shark sightings in the Philippines, I hope your new rash guard serves you well. Thanks so much for choosing The Dive Compass!

What a cute and functional way to dive in Bonaire! The top fit beautifully and feels very substantial. The sea foam green matches beautifully with the Octopus print and is very visible while submerged. I felt both sun-safe and thematically glamorous!

Hi Susan, I'm so glad to hear you love the rash guard! It sounds perfect for your Bonaire dives. Thanks for sharing your experience and the beautiful photo 🩵

Very nice design and material

Very nice design and material. For diving in warm waters or under the wetsuit - but it's too cute to hide it ;-) The size runs quite big, you could choose the smaller one.

This is a perfect rash guard!!

This is a perfect rash guard!! Exactly what I was hoping for. It fit perfectly, is so well made and great quality material, protected me from the sun and sea critters, and looks so great!! Perfect for snorkeling or diving or any other water activity. Got tons of compliments and everyone kept asking me where I got it!! Was thrilled to tell them about this company, which donates 10% to ocean conservation! Will definitely be buying more!

Super high quality rash guard

Super high quality rash guard, I wear them almost daily and this one looks like it will stand up to regular use. Beautiful colors, true to what is shown on the website. I’m 5’8” 165 lbs and the size L fits perfectly…snug in the right places but not super tight. It has nice long arms and long torso which suits me and has been hard to find in other rash guards. I’m super impressed!

The colour and pattern are so incredibly beautiful! Really brightens up the day to wear it, and the fabric is soft and comfortable. The size chart is very accurate, and the customer service is unmatched. There was a small issue with the first one I got, but I immediately got sent a replacement. This also works well under a wetsuit to make it easier to put on, and protects well against the sun without feeling too hot.
