The Haven XL is a great product that took a couple of sleeps to get used to and learn the secret is keeping the mattress properly inflated; if it is low the whole thing sags. The Achilles Heel is the mattress, so bring some Gorilla Tape in case repairs are needed. Inflating the mattress in the pouring rain is also a bit tedious but you can guy out the fly for some cover, or put a tarp up first and work under it. My only other whinge is the straps are too short for my liking; longer ones would be nice.
If you have any questions or issues, email the company. Dealing with Derek is always a pleasure; he is a decent bloke who I think is as genuine in the flesh as he comes across in the videos and in his emails.
When I bought my Haven XL in 2022 I weighed 154kg (338lb), well above the 129kg (284lb) limit. Having watched Derek load one up with hundreds of kilos of weight I took the risk and have had no issues. I'm now under 140kg (280lb) and dropping but have since switched to a different brand of lay-flat hammock which is rated well above my weight and has other features I like the Haven XL doesn't have. I am also now the Australasian Distributor for the other brand, by the way. Having said that, the Haven XL has features my brand doesn't, such as the fly can be guyed out to provide an awning to sit under and the Haven XL has some handy interior features like the pockets and so on, but it is heavier.
If you're moto-camping, horse camping or bicycle camping, car camping or don't have to hump the 3.5kg far and want a tent/hammock you can sit in like a seat, sleep in and so on; this is a great product from a really decent company. While as I said I no longer use it myself, there's no way I'll sell my Haven XL as it gives my customers the chance to choose for themselves which hammock they prefer. So far I haven't lost anyone to Haven XL but if I did, terrific! At least I know I helped a fellow outdoors lover get a great night's sleep. The Haven XL is a little bit more expensive than my brand but the old saying 'buy once, cry once' holds true. Quality always wins and the quality and enjoyment of the Haven XL will remain long after the price is forgotten. I just ordered their Hammock LED Lights and I know it will be just as Derek says it is in the video. If you buy a Haven XL I know you'll love it.
