SIZE GUIDE

WETSUIT SIZING

Our size chart can help you a lot when choosing your wetsuit.

Recommend that you choose the larger one if you are between two sizes.

Key Rule: Your Weight > Your Height

Between Sizes? SIZE UP!
If your weight is at the upper limit of a size (e.g., 75kg at S/M boundary), Usually choose the larger size (here, M).

Your neoprene wetsuit should be a little bit tight on the dry land. This is normal, due to neoprene’s feature, you may feel right in the water.

Notice that you need to size up if the wetsuit limits your breathing or arm movements in the water.

SUMARPO is providing a fitting-size service. If there are any problems, please feel free to contact us.

3-STEP WETSUITS FITTING GUIDE

▌STEP 1: Prep Work

Keep Skin Dry: Dry skin = smoother wear/removal.
No Tools Needed: SUMARPO’s slick inner fabric requires NO plastic bags/lubricants.
Trim Nails: Avoid scratching inner lining (use fingertips only).

▌STEP 2: Smart Wear Technique

Start at Feet:
→ Pull up gradually like socks to hips, avoiding twists.
Arm Entry Hack:
→ Roll sleeve cuffs into a "doughnut," push through with palms (not fingers).
Zip Like a Pro:
→ Lean forward to start zipper → slight squat to adjust → secure zipper cord end to collar tab.
(Forceful zipping damages seals!)

▌STEP 3: 5-Point Fit Check

Area	Perfect Fit Signs	Warning Signs
Neck	Below Adam’s apple, 1.5 fingers fit	Choking/gaps
Armpits	No bunching when arms raised	Folds/tightness
Chest	Light pressure, easy breath	Restricted breathing
Wrists	Cover wrist bone ±1cm	Cutting forearms/too short
Ankles	Ends at calf’s lower 3/4	Digging in/bunched fabric
