Fits very well, I was able to make all the adjustments necessary to fit me. The instructions are good so read them. I have not deployed the jacket yet. I also have worked out how to attach the MOB1. The tether works as expected and attaches to the jack lines with the clips. All in all, I am very pleased and recommend buying this life jacket.

I purchased this life jacket in January and, although I have (fortunately) not had the opportunity to use it in a real emergency, I have used it several times. The materials and workmanship are excellent and the jacket is very comfortable to wear, despite being an offshore jacket, which is bulkier than many other “coastal” items (the jacket has a light, a built-in hood and can easily accommodate a PLB). For a more in-depth analysis, look for the Yachting Monthly review published in 2022.
There are only two “issues”: the backtow system does not appear to be all that easy to be repacked if the jacket has been activated and the system deployed. The manual is not very clear on this and the videos on the TemO website refer to older and different versions. I hope TeamO will address this by publishing an updated video for the current system. Otherwise, it would probably be a wise idea to open the jacket and record a video showing how the system is packed for future reference.
The second issue is due to Brexit: if, like me, you plan to buy this life jacket from abroad, be prepared to pay very high customs duties. It's not TeamO's fault, clearly (they seem to try to keep prices low), but if you end up paying 30% more than the listed price, other products might become more interesting. Of course, you'll have to give up the backtow system as TeamO is the only manufacturere to offer a similar solution.

I had a chance to use my new vest this October on 14 days offshore sail. It fits very well no problem to wear it many hours and the materials seems good and durable. Considering my heigh almost 2m i would appreciate even longer straps between legs (always easy to shorten than other way). I haven't fall over yet but once it happens, I will write the second part of review.

I have purchased the lifejacket for a specific trip off-shore in the pacific, it has arrived in a short time. I must say I am very happy with the overall product, even in warm climates was very comfortable to wear and the materials seem very nice and sturdy.
I can only point out 2 elements that got me to rate it "only" 4 and not 5:
1. The light that comes inside the lifejacket was not exactly new. Manufactured in June 2021 with only 1/3 life left, expiry date June 2026.
2. I have purchased the lifejacket and had it shipped to Italy. As it arrived I had to pay about 25% of taxes on top for the import. I know this does not depend on TeamO but it would be nice to have mentioned on the site the possible additional costs related to importation in EU.

We received our 170N life vests within two weeks of placing our order. We live in Texas and expected shipping from the UK to take longer. The vests are comfortable to were while on deck. My wife and I are leaving Galveston in April for our years long cruising life and I purchased these life vests because we are expecting to be on watch alone at various intervals. We both clip in our tethers and use jack lines when necessary to go forward while underway.. Neither of us has ever fallen overboard and this is our greatest fear while underway. This vest appears to provide the best possibility for survival if one of us fall overboard while alone on deck.
