    Exped downmat

    Anyone use one of these? I bought it recently, but haven't had a chance to use it yet. But boy it's comfy to lie on - compared to the closed cell foam mat I was using. And will take a lot less space in the panniers, too.

    I never tried the exped but own a Big Agnes insulated aircore which is similiar except BA uses a synthetic fill rather than down. It is very comfortable. Because the exped is down, you have to use their pump to keep the moisture out which may or may not be an issue.

    +1 on the Big Agnes aircore, great for chilly Montana nights. In compression sack it's about the same size as a can of coke.

    Hi Steve

    yes I'm using it. Small, light and very comfortable to sleep. I had once the problem that the downmat loses air in the night - I heard this problem of somebody - and I'm checking if I have the second time this problem...

    Alternativly Exped has also a syntetic filling called Synmat.

    If the Exped down mat is anything like the Exped tents, it should be awesome!

    I used one in the Himalayas recently (-10deg inside the tent), and it's a fantastic bit of kit. I bought the '7DLX' or whatever it's called - it's the longest, widest one they do, but without the bulk of the 9cm model. Packs up WAAAAY smaller than a normal Thermarest, but is three times as thick when inflated, much warmer and more comfortable. Love it. Good choice.

    I have used one in the UK for the last 2 'summers'. It is very comfy and warm to sleep on.
    It stops the damp waterlogged ground sucking heat out of you from underneath.

    No problem using the supplied bag/pump.

    I use the chair converter and find it really useful for sitting reading in the tent.

    Yes it's a good product - I bought a TAR ProLight 2,5 short additionally when the Exped loses the air.
    The TAR has a bigger packing volumne, I can not sleep on it without pain, no pillow bag, and nearly the same weight. I even think that the pump is better instead of blow up the mattress with your lungs. In high altitude I need my breath - it was very hard to get air in blow up mattress. I also talked about this topic with a person who made expedition in the Himalaya. She said that blow up the mattress was one hardest jobs on this trip.

    Absolutely! Thankfully I was using the Exped (the pump is great) so I didn't have to use lung power to inflate the mattress, but we did find that packing the mats and the sleeping bags into their stuff-sacs at altitude (4,000-5,000m) was so tiring we had to have rests half-way through to get our breath back.

    My partner and I both had Exped mats, and neither had any problem with deflation.

    Thanks for the info.. Question - why can't we use our cycle pumps to inflate this Exped mat? Exped is great for tents - have one and the product design and materials are exceptional. I swore off air mats years ago - if anyone can do it right Exped could.

    I think the stuff-sac-inflation-system is actually pretty efficient (and very clever) - I'm pretty sure that a bicycle pump would take longer and be more tiring.

    What's the difference between the downmat 7 (which I have) and the downmat 9?

    To trivially answer mrpincher "Question - why can't we use our cycle pumps to inflate this Exped mat?" - because the valve is nothing like a shrader. I think one of the main design requirements for this mat was to not require a (heavy) pump. It might be theoretically possible for a company to make a mat that assumes you have a bike pump handy, but who knows if there's a market?

    Because bike pumps don't put out enough volume. They are made made for high pressure.

    OK - well then

    So these are not like the Thermarest, where you just puff a bit to firm it up -they don't self inflate at all. Initially the thought of goose down in an inflatable mattress was interesting. Upon checking the R value, cost and weight of my two 20+ year old foam pads.....its nice to hear this Exped pad is available and you folks approve.

    Kudos to Exped for exemplary customer service. I had two Exped mats which were out of the stated warranty period. My first, a Downmat 7, had developed an extremely slow leak that left me on the ground at ~2AM. Couldn't find the leak even with submerging the mat one section at a time. My second mat, a Synmat Deluxe 7, also had a slow leak that I had to re-inflate in the wee hours...not fun. After contacting via email, I shipped both a few weeks ago for assessment. I received new versions of both mats today via FedEx. The new Downmats have built-in pumps. My old one used the bag to inflate.
    I raise my glass to Exped today as I now have two very comfy mats for next season!

    I have 2 Synmat 9's, excellent, very comfy. only downside is they are bulkier then your average thermarest (inflated) and as a result 2 of em in a 2 man tent is a bit of a squeeze. Also you have to deflate/inflate every day which can be a bit of a pain compared to a foam pad.

    I've got the Exped Downmat 9....used it about 70 nights so far....I find that I have to inflate/adjust it very carefully to be happy. Too much pressure and it's too hard...too little and my butt sags down too far. Unfortunately getting it set right takes more effort than I care to spend for 1 night's sleep so my GF's sort of taken it over and I'm using one of my regular Thermarests that requires little thought to be comfortable.

    If I was setting up a base camp for a couple months like I did on the beach in Mexico last winter I'd use it since the effort is worth it for many days of sleeping without having to set it up again and again.

    For an overnighter I'll stick with my thermarest.
    safe riding - Vik

    I got a chipped foam Exped , It self inflates like a Therma rest . but is much thicker when it does .

    Breath has moisture and mildew loves moisture .. I used the pump sack on my Irish trip
    and the Stevenson Warmlight Down Air Mat took in moisture because it happened to be
    at Dew Point when I did the inflation, and got a slow leak from the coating deterioration from the mildew..

    The synmat/downmat have a built in pump, it is essentially an air matress like you'd use on a lake, but better made and it has an R value unlike your average generic airmat.

    I have the Exped downmat 9. I've used it for a couple of seasons both for winter camping and bike tours. For winter you can't beat the 8.5 R-value, and the 3.5 inch thickness is really nice. On bike tours, the R-value is not a factor, but the thickness makes it comfy. I got mine just before they went with the integral pump, so I'm stuck with the stuff sack inflation method which is cumbersome but dooable both in winter with cold hands, and in summer in my one person tent. The down sides are that it doesn't compress very small, and the stuff sack inflation process is time consuming. Also, even though I have never blown it up by mouth, I suspect some moisture has gotten into the down, because it smells a little foul when I deflate it.

    I've been looking at the Thermarest Neo-Air. Nice thickness, compacts to the size of a softball, but can be noisy as you toss and turn.

    Stevenson has been making their Down-air-mats by hand for 30 + years ,
    may send my bag back and have it altered to use someone else's Rectangular D-A-M
    the bag with 2 Down filled tops and a separate zip connected bottom
    is marvelously warm ,
    but the bottom is shaped for their Matt outline a rather a coffin like 6 sided shape..
