O'NEILLMen's Boost 300g Drysuit

As a diver I have had my fair share of drysuits that I have been issued or purchased for recreational use. I bought this drysuit specifically for jetsking during the winter months. Where water temps drop to high 30's and air temps go as low as 18 below. I was hesitant at first about the neoprene neck due to the fact i knew it would let some water channel in, but was not sure how much. I was willing to take the risk because I did not want another latex or silicone neck for the comfort factor. I have been using this suit for about a month now and love it. I purchased a LARGE, I weigh 180lbs and 5'11 with broad shoulders. This size was perfect for me, I wear 2 sets of tight thermals and 2 pairs of sweats and still have plenty of wiggle room for tricks and maneuvers. From body movement etc air builds up in the suit this also adds a buoyancy factor as well. This also aids in keeping you afloat when you get tossed off at 30mph and keeps water out. I have fully submerged myself and watched air bubbles release from the neck under the water, after all of the air was purged out the amount that leaked in was about 6oz. So i decided to buy a sauna suit to wear as my last layer and that works perfect. All in all well made, water tight, ridged zipper, great price, added features that I did not know before buying was that comes with internal suspenders to keep crouch up and external recessed cuffs on top and bottom perfect for booties and gloves..

I bought the drysuit to kiteboard in Florida. I was between this and a Kokatat Meridian. I ruled out the Ocean Rodeo and Lucifer suits. Drysuit's are "breathable" (let's air in, keeps water out) because of their membranes. The Gore Tex patent expired a long time ago, so I felt like I would pay a lot for the name in a Kokatat. Plus, I'm using the suit in salt water, and I don't know how salt affects the breathability.The neck is neoprene, so it does let water in if submerged, just like a wetsuit. My tshirt gets at least wet around my neck, depending upon how much I get dunked/ superman. But, it's easy to get on and off and much more comfortable than a rubber seal around my throat. If you spend a lot of time in the water above your chest, this probably isn't the suit for you.The zipper on the back is nice because it's not in the way. But, I still haven't figured out how to get in and out of it w/o some help.The suspenders on the inside are nice - it allows you to hang the suit from your waist when you're not in the water.It was a hard decision for me between a top of the line suit for twice the money, or the Boost. I feel like I made the right decision and I'm happy with the suit.

Seams leaked around the legs pretty seriously. After being in the water for about 45 minutes, I had approximately a half gallon in the suit. It was enough to soak my floor when I took it off. I really like the look and the fit of the suit, but unfortunately it leaks way too much through the seams.

Works as expected but the zipper being on the back makes an already stiff and hard to close zipper a difficult task to do alone.Comfortable but makes a lot of noise when walking and moving around

Lower price point than a lot of dry suits, but quality is not compromised. Works well with cold weather stand up paddle boarding. UPDATE 12/2016: A year after buying this suit I'm updating my review and making it four stars instead of five. I still recommend it enthusiastically, but I ran into a problem with the zipper that you may be able to avoid if learn from my mistake: The zipper works well as long as you keep it well lubricated with an appropriate zip lubricating product. It worked well for me last season with the lubricant on it, but this season I neglected to reapply the lubricant and the zipper failed to catch properly. Once it came off the zipper track, there was no way to get it back on track and I had to send it to O'Neill for a potential $100+ repair [they ended up replacing the suit for free, see below!]. IF YOU DON'T MAKE MY MISTAKE AND LUBE THE ZIPPER PROPERLY, YOU SHOULD AVOID THE PROBLEM I RAN INTO. The zipper is EXCLUDED from the manufacturer warranty, so you must pay attention to this issue or else pay for a repair. It's a little crazy that they would exclude this vulnerable part of the suit from their warranty -- it's almost like an admission that they expect the zipper to need repair at a higher rate than normal. UPDATE 12/13/2016: I just talked to O'Neill and learned that they immediately shipped a replacement suit, for free, to me after they received my damaged suit last week. So even though the zipper failed, I can say that customer service did not fail and in fact exceeded expectations by replacing this suit out of warranty. Great product, great customer service.

Does the job as a dry suit (without footies). Keeps you dry-ankle to neck. However design of neck neoprene is terrible. Way too high, stiff and choking issue. Did multiple cuts to get comfort OK. Per other reviews it seems this is common complaint and cutting it down is common fix. better than having it leak. Zipper is OK. waterproofing at Ankle and wrist braces are fine. sizing was as desired. Gave it high rating because price is very favorable compared to other options considered so did not count the neck issue (since fixable) too harshly in rating.
