Detailed Reviews

1. Henderson Thermoprene 5mm - Best Overall

Our Rating: ⭐⭐⭐⭐⭐ (4.7/5)

The Thermoprene is the wetsuit trusted by dive professionals worldwide. At $300, it delivers premium warmth and durability without premium pricing.

#### Pros

• • Excellent warmth - Thermoprene material warmer than standard neoprene
• • Durable - Glued and blind-stitched seams, lasts 5-7 years
• • Great fit - True to size, comfortable cut
• • 10-year zipper warranty - YKK zippers, virtually indestructible
• • Affordable - $300 for this quality is excellent value
• • Available in men's and women's - Proper gender-specific cuts

#### Cons

• • Basic aesthetics - Functional black, not stylish
• • Heavier - Slightly heavier than premium suits
• • Back zip - Requires buddy assistance

#### Key Specifications

• • Thickness: 5mm
• • Zipper: Back zip, YKK (10-year warranty)
• • Seams: Glued and blind-stitched
• • Material: Thermoprene neoprene
• • Water Temp: 65-75°F ideal
• • Gender: Men's and women's cuts available

#### Why We Recommend It

The Thermoprene is the wetsuit I've owned for 6 years, 250+ dives. Still warm, still durable, zipper works perfectly. At $300, it's the sweet spot—warm enough for temperate water, durable enough to last years, affordable enough to not stress about minor tears.

The 10-year zipper warranty is legendary. I've seen 15-year-old Henderson suits with working zippers. That alone is worth the price.

#### Who Should Buy This

• • Divers in temperate water (California, Mediterranean, Florida)
• • Those wanting quality without premium prices
• • Dive professionals (durability matters)
• • Anyone doing 20+ dives/year
• • Divers prioritizing warmth and longevity

2. Cressi Fast 3mm - Best Tropical

Our Rating: ⭐⭐⭐⭐ (4.5/5)

The Fast 3mm is perfect for warm water diving—light protection from sun and jellyfish while maintaining maximum flexibility and not overheating.

#### Pros

• • Lightweight - Easy to pack, minimal luggage weight
• • Affordable - $180 for a quality 3mm suit
• • Flexible - Barely restricts movement
• • Quick-drying - Minimal water absorption
• • Multiple colors - Black, blue, pink options
• • Comfortable - Soft neoprene, no chafing

#### Cons

• • Only for warm water - Useless below 75°F
• • Less durable - 3mm tears easier than 5mm
• • Basic features - No fancy linings or coatings

#### Key Specifications

• • Thickness: 3mm
• • Zipper: Back zip
• • Seams: Flatlock stitched
• • Material: Standard neoprene
• • Water Temp: 78°F+ ideal
• • Gender: Men's and women's versions

#### Why We Recommend It

The Fast 3mm is my Caribbean/Asia travel suit. At 3mm, it provides sun protection and light thermal insulation without feeling restrictive. In 82°F water, it's perfect—warm enough to prevent chill after 60-minute dives, light enough to not overheat.

At $180, it's affordable to replace every 3-4 years when it wears out. Don't expect 7+ year lifespan from 3mm suits—thin neoprene degrades faster.

#### Who Should Buy This

• • Tropical vacation divers
• • Those diving Caribbean, Red Sea, Southeast Asia
• • Divers who overheat easily
• • Anyone wanting lightweight travel gear
• • Warm water specialists

3. Cressi Morea 3mm Women's - Best Women's Wetsuit

Our Rating: ⭐⭐⭐⭐½ (4.6/5)

The Morea is cut specifically for women's bodies with proper proportions in shoulders, torso, hips, and chest. Finally, a wetsuit that fits women properly.

#### Pros

• • Women-specific cut - Narrower shoulders, shorter torso, wider hips, chest accommodation
• • High-stretch neoprene - Ultra-flex material, easy donning
• • Affordable - $200 for women's specific suit
• • Comfortable - Proper fit eliminates pressure points
• • Multiple sizes - Better size range than unisex
• • Quality construction - Cressi reliability

#### Cons

• • 3mm only - Not available in 5mm or 7mm
• • Warm water only - Limited to tropical diving
• • Basic features - No premium linings

#### Key Specifications

• • Thickness: 3mm
• • Zipper: Back zip
• • Seams: Flatlock
• • Material: High-stretch neoprene
• • Water Temp: 78°F+
• • Gender: Women's specific

#### Why We Recommend It

The Morea is the suit I recommend to female divers frustrated with unisex wetsuits. The fit difference is dramatic. Unisex suits gap at the chest or squeeze at the hips. The Morea fits properly—huge improvement in comfort and warmth.

At $200, it's one of the most affordable women's-specific wetsuits. For tropical diving, it's perfect.

#### Who Should Buy This

• • Female divers of all levels
• • Women tired of poor-fitting unisex suits
• • Tropical water divers
• • Anyone wanting affordable women's wetsuit
• • Divers prioritizing fit over features

Wetsuit Fit Guide

Wetsuits MUST fit snugly:

A proper wetsuit should:

• • Feel tight when dry (wetsuits stretch when wet)
• • Have NO GAPS at neck, wrists, ankles (water enters = cold)
• • Require effort to put on (too easy = too loose)
• • Allow full range of motion (can reach valves, bend comfortably)
• • Not restrict breathing (chest too tight = dangerous)

Too loose: Water flushes in and out, you freeze

Too tight: Restricted breathing, exhaustion, can't dive safely

Just right: Snug everywhere, no gaps, can breathe and move freely

Thickness by Water Temperature

Water Temp	Recommended Thickness	Example Locations
Above 78°F (26°C)	3mm or rashguard	Caribbean, Maldives, Red Sea
72-78°F (22-26°C)	3-5mm	Florida summer, Hawaii, Bahamas
65-72°F (18-22°C)	5mm	California, Mediterranean, Australia
58-65°F (14-18°C)	7mm or 5mm + hooded vest	Pacific Northwest, New England, UK
50-58°F (10-14°C)	7mm + hood/gloves or drysuit	Winter diving, Great Lakes
Below 50°F (10°C)	Drysuit required	Ice diving, Arctic

Individual tolerance varies: Some divers freeze in 5mm at 70°F, others are comfortable. Start with chart recommendations, adjust based on experience.

Frequently Asked Questions

Q: What thickness wetsuit do I need?

A: 3mm for tropical water above 78°F, 5mm for temperate 65-78°F, 7mm for cold 50-65°F. Most versatile choice is 5mm—works in widest temperature range.

Q: How should a wetsuit fit?

A: Snug everywhere with no gaps. Should feel tight when dry (stretches when wet). No water should flush at neck, wrists, ankles. If water flows in and out, too loose—buy smaller.

Q: How much should I spend on a wetsuit?

A: Budget $200-400 for quality. Under $150 risks poor seams and short lifespan. Over $450, you're paying for marginal improvements. Sweet spot is $250-350 for suits like Henderson Thermoprene.

Q: Back zip, chest zip, or zipper-less?

A: Back zip: Most common, easy with buddy help, slight water entry. Chest zip: Warmer (less water), harder to don solo. Zipper-less: Warmest, most flexible, hardest to put on. Most divers get back zip.

Q: How long do wetsuits last?

A: 3-7 years depending on use and care. Neoprene degrades with sun exposure, compression, and salt. When suit gets loose or neoprene thins noticeably, replace it.

Q: Can I buy a wetsuit online?

A: Risky—fit is everything. Buy from retailers with free returns (Amazon has good return policy). Better to try in shop, then buy online if cheaper.
