The Weezle Undersuit Extreme Plus is the warmest model in the Weezle lineup, built for divers who need serious insulation under a dry suit in harsh conditions. It is the right choice when cold-water comfort, long exposure times, and dependable thermal protection matter more than saving bulk compared with the lighter Compact and Extreme.
Product Overview
The Extreme Plus is the heaviest and warmest undersuit in the Weezle range. At 3.2 lb (1440 g), it is aimed at divers facing extremely cold water, long decompression stops, or ice-diving style conditions where a lighter undersuit such as the Compact would leave too little thermal margin. Snugpak positions it as the boundary-pushing option for maximum warmth beneath a tri-laminate drysuit.
Despite the added insulation, the suit follows the same practical Weezle approach rather than becoming overly stiff or awkward. Softie Premier insulation works with the TS1 thermal inner lining and Paratex Light outer fabric to hold heat while remaining more flexible than many traditional heavy undersuits. A two-way YKK front zipper, thumb loops, ankle stirrups, elasticated waist, reinforced shoulder panels, and multiple storage pockets keep it usable for real diving and not just theoretical warmth.
For divers putting together a cold-water setup from our broader selection of scuba equipment, the Extreme Plus makes the most sense when warmth takes priority over pack size. If you mainly dive temperate conditions, the Extreme is usually the better balance. If you regularly face very cold water, long bottom times, or decompression-heavy diving, the Extreme Plus is the model built for that job.

Weezle Undersuit Extreme Plus Size Guide
The Extreme Plus uses the same Weezle size guide as the Compact and Extreme. The waist measurement below is the unstretched waistband. The manufacturer notes that the elastic gives roughly 2-3 in (3-4 cm), and divers who dive with extended arms should add 3-4 in (8-10 cm) to their desired arm length.
How to Measure
- Waist: Measure between the hip and lower rib.
- Hip: Measure the widest part of the hip and seat.
- Chest: Measure around the nipple line.
- Torso: Measure from the top of the sternum to the crotch.
- Arm: Measure from the wrist bone to where a shirt shoulder seam would sit.
- Leg: Measure from the crotch to the ankle bone.

FAQ
It is designed for divers facing the coldest conditions in the Weezle range, including extremely cold water, long decompression stops, and ice-diving style use where maximum insulation matters more than compact pack size.
Yes. Snugpak specifically describes the Extreme Plus as suitable under a tri-laminate drysuit, where its heavier insulation can be used to full advantage in very cold water conditions.
Not necessarily. Snugpak notes that many divers have reduced the weight on their belts after switching to a Weezle undersuit. Even so, any new drysuit and undersuit combination should be checked in controlled water before a serious dive.
The manufacturer recommends wearing as little as is comfortably possible to let the moisture-wicking inner fabric perform properly. If you do add a base layer, choose a high-wicking fabric rather than a material that holds moisture.
It is bulkier than the Compact and Extreme, but Snugpak states that the Extreme and Extreme Plus remain more flexible than most traditional undersuits. It is built to maximize warmth while still allowing practical movement underwater.
Snugpak explains that quilting restricts air flow and creates cold spots at the stitch lines. The Weezle design uses a self-supporting fill so the undersuit can insulate effectively without those cold spots.
The Compact is the lightest option for warmer conditions and travel. The Extreme is the mid-weight choice for most cool-to-cold water diving. The Extreme Plus is the warmest model for the harshest conditions. If you want help deciding which fits your diving best, email sales@bluewaterphotostore.com.
