Question: May I use it as a waterproof tarp over an outdoor bed?
Document: Product came on time and is a great product! This blanket would serve equally well as a picnic blanket or an outdoor game/concert blanket. Definitely blocks wind on one side and is soft and fleecy on the other. I will use this for all of the above!
I have owned a Mambe extreme blanket for just over a year and it has proven one of the best outdoor gear investments I have made in a long time. My family does a lot of activities outdoors here in Oregon like hiking, cross-country skiing, and visiting the coast. Often, wind and rain are part of these outings and this blanket has warmed us after playing in the surf, shielded us from cold mountain rain storms, and served as a warm, dry picnic blanket we can throw down on the snow in the back country.This blanket is noticeably warmer than other outdoor blankets I have used in the past, presumably because of the insulating layer they place between the fleece and the waterproof nylon.
Tonight, we had a football game in crazy pouring down rain - it was so windy that umbrellas were useless. I wrapped myself in my waterproof blanket and watched the whole game. I was warm, I stayed dry - it was perfect. If you are hesitating about the price - just do it. It was worth every penny - The fleece quality is outstanding and high quality - nothing I have compares to it. I also bought an extreme weather poncho blanket (one with a hood and pockets in the blanket)- we use both all the time.
It was exactly as advertised, super warm. Great for outdoor sporting events. Easy for travel and durable. Highly recommend it.
This is the best waterproof blanket ever EVER. We have used this blanket in every type of weather and I cannot say enough about it! We have 3 boys so we are always attending some type of sporting event. Last month when it was sunny, we folded it over and it served as a cushy bench seat and my boys like to hide under it to block the sun and play their electronics :) Last week, it was chilly and windy and we used it as a blanket and it cut the wind. I was so nice and toasty that my friends wanted to come under my blanket also - it was big enough for 3 adults to share!
I bought a few extra of them that I use for things like climbing ropes and harnesses as well as camping gear.
Item arrived before due date. The blanket is very well made, i know i will get a lot of good use out of it for a very long time. I could not be happier, also it is made in AMERICA and that makes it even better.
I use a small Mambe extreme blanket as a lap blanket when I'm taking our puppy for scooter walks with my mobility scooter. I just got it yesterday, but I LOVE it. It is really, really warm, and the small size is perfect for a lap blanket--big enough to tuck under but not so big as to be inconvenient. Great job, Mambe.
I can see why the Mambe company would also market this as an emergency blanket; if you were wet and cold, it would sure prevent you from losing body heat and in turn help stabilize and raise your temperature. Overall, I think the blanket is a fantastic piece of technical equipment.One final thought is on the stuff sack that the company sells. I'm not sure if they come with the blanket automatically or not, but I would highly recommend getting one as they are well worth it. They are super durable and do a good job of storing and protecting the blanket when not in use.
Item is great, but pay no attention to comments that suggest this blanket is too small. Actually, i think the large is much too big for one person. Large blanket would be great for sharing with someone, but small one is perfect size for individual use.
