The ultimate baselayer for use under a drysuit. Made using Polartec® Powerstretch® originally developed for NASA, the Xerotherm traps a layer of air - a much better insulator than water next to the skin, keeping the wearer drier and more comfortable. The range is designed to be worn under another undersuit or on its own under a neoprene drysuit. The knit of the Xerotherm fabric produces the fastest wicking effect of any of the products in the fourth element product range. Moisture is drawn out through the fabric along fine fibres and then spreads out over the outer surface. This maintains a thin layer of air next to the skin. This is so effective in the Xerotherm that some wearers report experiencing minor suit leaks during the dive without even noticing until after the dive. "The performance is superb". This was the reaction of Doug Allan, world-renowned and award-winning underwater filmmaker and author after testing the Xerotherm in -2 degree (29F) water inside the Arctic Circle in Svalbard, whilst shooting sequences for the BBC production The Blue Planet. The Xerotherm is specified by the FBI Dive Teams, Norwegian Navy and British Police Diving Units.

With flat seams and a long body to ensure that no separation between top and leggings develops, the top is the ideal next to skin layer under a drysuit. Thumb loops keep the sleeves in place whilst donning the drysuit and should be removed from the thumb and pushed back through the wrist seals prior to diving.

It works, but rinse and spit
Great for at home but not on the go. Definitely need to rinse and spit after a while. Does work though

Perfect for Travel — Amazing Foam, Great Taste, and Long-Lasting Freshness
Flavor Name: A Coconut+Green Tea+Peach
These Popboom mouthwash tablets seriously exceeded my expectations. They foam up really well, much more than other tablets I’ve tried, and they leave my mouth feeling clean and refreshed without that harsh, overpowering burn you get from liquid mouthwash. It’s a really nice break from traditional toothpaste and works great for bad breath, even hours later. As someone who travels frequently, this product is an absolute must-have. The tablets are compact, lightweight, and spill-proof, so I can throw them in any bag or pocket without worrying about leaks. They’re perfect for situations when you don’t have access to water but still want fresh breath—just pop one in and you’re good to go. Flavor-wise, they’re fantastic. Coconut is hands-down my favorite, and I also tried the trio pack to sample different options. Peach was enjoyable, while matcha wasn’t really my thing (I’ll be giving that one away), but overall the flavors are fresh, pleasant, and not overwhelming. These definitely foam up better than most similar products on the market. I also love how convenient they are—no bulky bottles, no mess, and nothing heavy to carry around. The size is perfect, the taste is great, and I find myself reaching for them throughout the day. I’ve already reordered and will continue to keep these stocked. If you haven’t tried these yet and you’re always on the go, what are you waiting for? These are a game-changer for travel, work, or anytime you need quick, effective mouth freshness.

Convenient and taste good
Flavor Name: A Coconut+Green Tea+Peach
These are so handy to keep in my purse and I like all of the flavors. They really help make my whole mouth feel cleaner, not just my teeth.
