class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>There are a number of features that a diving <a href=\"https:\/\/scubatechphilippines.com\/scuba_blog\/diy-sidemount-wreck-diving-helmet\/\">helmet<\/a> must have:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Top ventilation holes<\/li>\n\n\n\n<li>No permanently affixed EVA or polystyrene foam lining<\/li>\n\n\n\n<li>Adjustable suspension<\/li>\n\n\n\n<li>Minimal impact protection<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Top-ventilation-holes\"><\/span>Top ventilation holes<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Divers inevitably release bubbles and that gas will accumulate inside the helmet unless there are some ventilation holes at the top to allow it to escape. Some helmets come with ventilation holes, otherwise, you can add some yourself with a drill.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"No-permanently-attached-EVA-or-polystyrene-foam-lining\"><\/span>No permanently attached EVA or polystyrene foam lining<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Unfortunately, most modern climbing and kayaking helmets are designed to be lightweight and built around a solid EVA or polystyrene foam lining. The foam is far too buoyant when you are diving. I&#8217;d guess within the region of 1-2lbs+ positive <a href=\"https:\/\/scubatechphilippines.com\/scuba_blog\/ultimate-guide-scuba-diving-buoyancy-control\/\">buoyancy<\/a>; which is distracting at best, and dangerous at worst. Removing these glued-in linings is impractical. <\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Adjustable-suspension\"><\/span>Adjustable suspension<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Because foam-lined helmets are impractical, you need to source a helmet that uses adjustable nylon strap suspension for support. If these helmets do also come with foam lining, it is typically either removable soft foam fabric or velcro-detachable EVA\/polystyrene blocks.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Minimal-impact-protection\"><\/span>Minimal impact protection<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Diving helmets don&#8217;t need the impact protection that comes with products designed for climbing. The main hazard in wreck and cave diving is usually limited to low-velocity collisions. That risk doesn&#8217;t necessitate an impact-protection-rated helmet. <\/p>\n\n\n\n<div class=\"scuba-b4-h2-2\" style=\"margin-top: 10px;margin-bottom: 10px;\" id=\"scuba-1905835709\"><div class=\"scuba-adlabel\">Sponsored Link<\/div><script async src=\"\/\/pagead2.googlesyndication.com\/pagead\/js\/adsbygoogle.js?client=ca-pub-9354033900485448\" crossorigin=\"anonymous\"><\/script><ins class=\"adsbygoogle\" style=\"display:block;\" data-ad-client=\"ca-pub-9354033900485448\" \ndata-ad-slot=\"2393012471\" \ndata-ad-format=\"auto\" data-full-width-responsive=\"false\"><\/ins>\n<script> \n(adsbygoogle = window.adsbygoogle || []).push({}); \n<\/script>\n<\/div><h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Option-1-Choose-off-the-shelf-helmets-for-diving\"><\/span>Option 1: Choose off-the-shelf helmets for diving<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Buying-dedicated-cave-diving-helmets\"><\/span>Buying dedicated cave diving helmets<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p><a href=\"https:\/\/www.lightmonkey.us\/helmet\">Light Monkey<\/a>,<a href=\"https:\/\/razorgosidemount.eu\/en\/product\/razor-side-mount-helmet-black\/\" target=\"_blank\" rel=\"noreferrer noopener\"> Razor<\/a>, <a href=\"https:\/\/www.diverite.com\/products\/retired-products\/helmet\/\" target=\"_blank\" rel=\"noreferrer noopener\">DiveRite<\/a> and <a href=\"https:\/\/www.mares.com\/en\/rigid-cap-3\" target=\"_blank\" rel=\"noreferrer noopener\">Mares<\/a> all sell diving helmets, but they cost quite a lot and some divers find that they don&#8217;t fit into the one-size-fits-all designs. These helmets aren&#8217;t built for heavy impact protection but <a href=\"https:\/\/scubatechphilippines.com\/scuba_blog\/flow-state-scuba-diving-skills\/\">focus<\/a> on being minimally buoyant and lightweight.

They range greatly in price, but a diver can shop at the low-end cost because they don&#8217;t need features that a dry-land user may want; such as internal air ventilation channels and antimicrobial sweat absorbent liner materials.<\/p>\n\n\n\n<p>Many of these helmets won&#8217;t have the necessary ventilation holes at the top. That is easy to remedy for yourself with a drill.<\/p>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-28f84493 wp-block-columns-is-layout-flex\">\n<div
