Often you hear: ".. better a tight suit, this is warmer!" WRONG! A tight suit has nothing to do with the heat output quite the contrary. 
The looser and matching suit is equally warm, even warmer due to the better heat layer between suit and body. 
In a looser and therefore fitting suit the muscles do not get tired, but this is the case in a too tight suit, because the muscles must "work" first against the suit. Also, the blood circulation is not restricted, which otherwise negatively affects the body heat and the overall physical performance. In addition, the whole movement is not limited by a too tight suit. When windsurfing the ability to move is very important. The matching suit is always the looser suit in relation to the size. 
Therefore always choose the size so that it is convenient and comfortable. Precisely not (too) tight!

- For the correct fit a convenient and comfortable feeling is always in the foreground
- When in doubt, always choose a size larger, important are the start datas of the ION size chart table
- ION is body contoured and therewith cut close in comparison
- If you are in the rear third of the data with your body data according to size table, always choose the next larger size

An example for the correct size selection
Your datas are: Height 180cm, Weight 78kg, Chest 99cm
According to the ION size table you would fit in size 50 and size 52. At size 50 you are already in the rear area, so already at the size border. We would advise you to the size 52. The size 50 would be definitely too tight, especially ION is body contoured. The size 52 will fit you in any case and has a comfortable feel. Your size is 52 / L.

Do you still have any doubt about the size choice you or are you unsure, just contact us >Contact<.  We'll be happy to help!

The ION wetsuit range covers a huge variety of operations. the new ioN Neoprene compass is designed to give you some advice in finding the wetsuit that‘s right for you:

Kitesurfen - important for kitesurfing: 
- flexibility in upper body/arms - robustness/abrasion resistance
- impact protection - comfort and warmth - progressive style

Windsurfen - important for windsurfing: 
- warmth in windy conditions - wind-chill protection
- wearing comfort/stretch in arms - technical features - shin protection

Wakeboarden - important for wakeboarding: 
- flexibility in upper body/arms - robustness/abrasion resistance 
- impact protection ribs - progressive color/style

Surfen - important for surfing:
- max. flexibility in arms/shoulder/upper body
- specialized snug fitting armpits and arm reach 
- important for paddling: water sealing/wearing comfort on neck
- abrasion resistance from double lined Neoprene

SUP - important for stand up paddle surfing:
- general robustness against ripping/abrasion by double lined protection fabrics 
and other construction features



Double Lined (DL)
If most of the suit is covered with jersey fabric on the outside, it is a „dl“ suit. the more double lined Neoprene, the more flex/abrasion resistance and color options, but also less windchill protection when exposed wet in windy conditions.



Double Lined (DL)
Instead of using skin Neoprene on the outside a jersey is laminated on the Neoprene sheets. It protects the Neoprene foam against ripping and makes it more robust than skin Neoprene. Normally it is also more elastic compared to skin Neoprene as it is not embossed on the surface. The downside though is a higher evaporative heat loss when the wet jersey surface is exposed to the Wind-Chill factor. But for some people the style factor by adding color and nice graphics to a wetsuit becomes more and more important and this is only possible with double lined Neoprene.
