A drysuit should fit snugly, but it shouldn't be excessively tight. The goal is to have a comfortable and effective fit that minimizes excess air movement inside the suit while allowing you to move freely. Here are some guidelines to help you determine if your drysuit fits correctly:
1. Comfort: The most important factor is comfort. When wearing the drysuit, you shouldn't feel overly constricted, and you should be able to move your arms, legs, and torso comfortably. Your range of motion should not be restricted.
2. Minimal Excess Air: While the drysuit should fit snugly, it shouldn't be so tight that it feels like a second skin. A small amount of trapped air inside the suit helps with insulation and buoyancy control. However, excessive air trapped inside can create discomfort and negatively impact buoyancy.
3. Movement: You should be able to move your limbs and body without feeling restricted or straining against the suit's material. During a dive, you'll need to perform various movements, so the suit should accommodate these motions.
4. Seals: The wrist and neck seals should provide a watertight seal without causing discomfort or cutting off circulation. The seals should prevent water from entering the suit while remaining comfortable.
5. Flexibility: A drysuit shouldn't hinder your flexibility. You should be able to squat, kneel, and move your limbs without feeling restricted.
6. Base Layers: Keep in mind that the fit of your drysuit may be affected by the type and number of layers you wear underneath. Ensure that your base layers allow for a proper fit without adding excessive bulk.
7. Zipper Closure: If the drysuit uses a zipper closure, it should close smoothly without too much effort. The zipper should be closed properly to prevent water from entering the suit.
If the drysuit feels too tight, it can cause discomfort, restrict blood circulation, and impact your diving experience. On the other hand, if it's too loose, it can lead to air pockets forming, negatively affecting buoyancy and making it harder to control your position in the water.
It's recommended to try on different drysuit sizes and models to find the one that fits you best. If possible, get fitted by professionals at a dive shop, as they can guide you through the fitting process and help you choose the correct size. A well-fitted drysuit enhances your diving experience and comfort underwater.
