Weighing just five ounces, the Mammut Alpine Mat UL Sleeping Pad weighs less than a bar of chocolate and is twice as luxurious when you're enjoying a warm night in the mountains.

weight of a feather

    Okay so this thing weighs next to nothing, literally cannot feel the weight of this pad strapped to my backpack. The perfect pad to get a little more warmth. I use it to protect my pump up mat which I've managed to puncture a couple of times and repair in the field. But this seems to work to keep those punctures at bay and also help the hips when bottoming out the pump mat. Folds up small and while I have not weighed the pad I don't think it even weighs 5oz which Mammut claims.

    Nice addition for cold weather trips

    • Familiarity: I've used it once or twice and have initial impressions

    I added this pad recently to extend the amount of time I can spend backpacking; it's very lightweight and it really improved my quality of sleep on a trip where the night temps were in the lower 40s. It also helped keep my sleeping system from getting dirty and/or soaked from ground condensation.

    For reference, my standard 3-season sleeping system consists of a Nemo Zor that I occasionally add the pillowtop cover to, a silk mummy liner, and a Big Agnes Kings Canyon quilt. Depending on the clothing I wear, that will keep me warm down to around 50F. To get into the lower 40s, I added this pad & an extra layer of clothing that I would bring for cold weather anyway.

    I doubt I would enjoy this pad on its own; luxurious sleep is my basic requirement when I'm outdoors, and this pad will not provide that. But as an addition to a sleeping system, it's PERFECT. I'm very happy with this.

    Did It's Job and Then Some!

    • Familiarity: I've put it through the wringer

    There are almost no reviews for this item anywhere on the internet so I will do my best to be very thorough on this one!

    Let's start with why I bought this pad over any other. I am a first and foremost dedicated hammock sleeper. I have backpacked over 500 miles in the last 2 years and have only slept on the ground 4 times (yes exactly four, my shoulders still hurt...okay maybe they don't but I really don't like the ground anymore).

    The biggest challenge with hammock sleeping is staying warm when the temperatures start to get down there. The main reason for this is because you are off the ground so there is a lot of air flow under you, and if you sleep in a classic sleeping bag you compress the insulation under you effectively cutting of 10-15 degrees (at least) off of the rating of your bag. I use the Grand Trunk Hammock Sleeping bag, which helps negate the crushed insulation problem to some degree but it can still get a bit drafty.

    I bought this pad to go on the John Muir Trail, where I knew that temperature below freezing were not only likely but to be expected for the time of year I was there. This is just below my comfort level with my hammock sleeping bag.

    I bought this pad to add back the extra warmth lost to drafts underneath the hammock. I did not want to carry anything heavier or bulkier than I needed to. While this folds so it is not the most trim profile compared to inflatable options when packed, it blows away every other pad on the market in terms of weight. It also has a much higher R value then any pad that is even close to its weight. For me it made this item a no brainer. 5oz for all that warmth? Done.

    It's second function was to serve as a pad for going to the ground if I had to. I did have to do this twice on the JMT. It certainly kept me warm, but let's be honest, this pad is very spartan as the only means of padding between you and the ground. I was lucky to have softer camp sites those two nights so this was still plenty comfortable for one night and definitely kept me warm.

    Overall this pad is killer, but you do have to know why you are buying it specifically. If this is going to be a stand alone dedicated pad and you are worried about weight I would say to look into inflatable pads or the other slightly heavier foam pads. Your back will prefer to carry the extra weight than to not sleep on it night after night.

    If you too are a hammock sleeper or you want to use this to supplement another pad for colder weather camping then look no further this is exactly what you are looking for.

    TL:DR?

    pros:
    -Ultralightweight
    -super warm
    -Flexibility makes it a great hammock pad
    -Durable for a CRAZY light pad (didn't even show wear on the JMT)

    Cons:
    -not very comfortable for a standalone pad for sleeping on the ground
    -will blow away in the wind if you turn your back at the wrong time (no seriously, it is that light)
