What wetsuit do I need?

Two questions, in order: how cold is the water, and where do your measurements land on the Mystic chart. Thickness first, then fit.

The bands below are the ones the Highwind advisor uses. The charts are Mystic's own, printed here exactly as the brand publishes them.

Starting point from the brand chart — confirm your size with the advisor.

Mystic junior wetsuits

Measurements verbatim from the brand charts. Wetsuit letters: S/M/L prefix-modifiers ST/MT/LT = tall, MS/LS = short-wide variants per row data. Harness charts include the matching Stealth/Ace spreader-bar size per harness size (bars sold separately).

How to read the size chart

Measure height, chest and waist and find the row where all three land. If two of the three point at one size, take that size — a wetsuit that is slightly snug when dry is right; a loose one flushes cold water and stops working.

Chest and height disagree by a size? That is what the tall (ST/MT/LT) and short-wide (MS/LS) rows exist for.

We’ll swap it. Unlike buying brand-direct (no exchanges, return shipping on you), we do true size exchanges on unworn waterwear — tell us the size you need and we’ll get it moving. Check the size chart on each product page first; when in doubt, ask.

Questions we actually get asked

What thickness wetsuit do I need?

By water temperature: 75°F+ shorty/top or boardshorts; 65–75°F 3/2; 58–65°F 4/3; 50–58°F 5/3 with boots and hood; below 50°F 5/3 or 6/5 double front-zip plus 5–7mm boots, hood and gloves. Mystic publishes size charts on each suit page.

How do I measure for a Mystic wetsuit?

The men's and unisex chart uses height, chest and waist; the women's chart adds a US size; the junior chart adds age. Find the row where your measurements agree.

I am between sizes — what do I do?

Measurements verbatim from the brand charts. Wetsuit letters: S/M/L prefix-modifiers ST/MT/LT = tall, MS/LS = short-wide variants per row data. Harness charts include the matching Stealth/Ace spreader-bar size per harness size (bars sold separately).

Mystic publishes tall and short-wide rows precisely for this. Ask the advisor with your height, chest and waist and it will read the chart with you.

Do I need boots, gloves and a hood?

5/3 with boots and hood

5/3 or 6/5 double front-zip plus 5–7mm boots, hood and gloves

Can I exchange a wetsuit that does not fit?

We’ll swap it. Unlike buying brand-direct (no exchanges, return shipping on you), we do true size exchanges on unworn waterwear — tell us the size you need and we’ll get it moving. Check the size chart on each product page first; when in doubt, ask.

How fast will it ship?

We begin processing orders the same or next business day. Standard delivery is estimated at 3–5 business days after dispatch. You’ll get the tracking number by email when the shipment is handed to the carrier.
