Buying a Wetsuit
1. Flexibility and buoyancy
All wetsuits are a trade off between flexibility and buoyancy. The more buoyant the wetsuit, the less flexible it is. The reverse is also true the more flexibility you have the less buoyancy there is. Unfortunately a triathlete needs both buoyancy and flexibility.
At the entry level suit the flexibility is often gained by making the wetsuit thinner around the chest panel; 3mm or 4 mm are often used. This gives you the flexibility you need at the right price point. An entry level triathlon specific wetsuit is usually between 100-160 GBP
The maximum thickness that the rules will permit is 5mm. So it would be illegal to use a 6mm or 7mm diving suit. The higher the pricepoint the more flexible materials and more flexible backings are used. This maintains flexibility while increasing buoyancy. The best combination is often said to be a 5mm neoprene body panels and 1.5mm on the arms and 3mm for the lower legs. This allows maximum buoyancy and flexibility, to optimize the swimmers stroke.
Top of the range suits are usually between 350GBP and 400GBP
2. What is the difference in speed?
The quality of the suit is also related to its speed. The most supple materials and most buoyant neoprene's are also the fastest. Top manufactures now coat their high end suits with a silicon coating, called CSC (Super Composite Skin), which helps the suit to slice through the water. The fastest suit will also have a “nano” coating which also traps more air between the slican and the suit and is claimed to increase buoyancy by about 4% . A top of the range 2XU V1 wetsuit (www.v1wetsuit.com
) for example, which also introduces an industry first, " catch panels on the arms". is argued to be over 90 seconds faster than a typical entry level wetsuit.
3. Custom Made or Made to measure.
Custom made suits are generally more expensive, but they should fit correctly. However, with ready made suits in so many sizes and open water swim lakes, such as (www.openwaterswim.co.uk) now available to test out your suit before buying, it is often easy, quicker and cheaper to buy an off the peg wetsuit, test it out and be confident of the fit. Never buy a suit without wearing it first and if possible try and swim in it before purchasing. 2XU, Blue Seventy and Orca for example offer between 10 and 15 different sizes per style, which fit most body types. If your body shape is out side of the norm, made to measure such as Snugg wetsuits may be your only option
You can customize many off the peg wetsuits. Check to see if the seems on the arms and legs are taped or not. If they are taped, it will mean that, the suit is designed to have arms and legs shortened; typically by up to 6 inches. This is a useful feature that most triathletes are not aware of.
5. Men's and Women's Sizes
You should not buy a unisex wetsuit, due to our different body shapes. Always look for male and female specific sizes. Some companies only offer 4 sizes to cover all the range for both men and women. This will mean that you will most likely end up with an ill fitting wetsuit.
6.Test out the wetsuit in Open water before buying.
If possible you should test out the wetsuit at one of the many open water swim venues that are springing up around the country. In a shop when you are sweaty and sticky you will be temped to buy a suit that is too big. Buying wetsuit that is too big is possibly the biggest mistake made by beginners.
7.What should the right size feel Like ?
Ensure that it is a snug fit. The arms below the elbow should be particularly tight, also the neck should be well fitted. If there's a gap the suit will soon fill up with water, which is very irritating when you are swimming.
This is a relatively new technology, but if the zip is bonded in place and not stitched it will allow much more flexibility.
These wetsuits are expensive, so check out the warrantees.
One year is the minimum you should aim for, the best companies offer 2 years.
Some people suffer from chaffing around the neck, which can be quite painful. This is another good reason to try out your suit before buying. Products such Bodyglide are very good to prevent this rubbing. It is recommended not you use petroleum jelly based products such as Vaseline as they damage the neoprene
