Product Reviews

Rated 5 out of 5 by from Just like home Took this with the sycamore mf to fit two kids on a backpacking trip. Fit two Nemo 20” pads in it, and there was definitely enough room to fit two adults. The bag, sycamore, was rated for 25f. The kids were fine at 40f. I think this concept downgraded the temp rating of my bag by 10 degrees while not adding much weight. My wife and I used the feathered friends version, which differs in two major areas: the pad on feathered friends fits in more securely and the thread count is better on the feathered friends. The weight is about six ounces more on feathered friends. Maybe it’s not higher but it’s a synthetic, slippery sleeping bag feel where the western mountaineering summer coupler is more like an 80-thread-count cotton sheet. I really bought these for myself. I’ve always wanted the WM summer coupler. I sleep wide, and this enables it. My wife was cold but the addition of the sea to summit silk liner made up for the difference. this makes the sycamore a fantastic doubles bag, or a sprawling bachelor utopia with absolutely no restriction on movement. And it weighed three pounds with the sycamore. Loved it. Best addition to a wm semi rectangular bag. Compressed with the sycamore mf in an 8L sea to summit compression bag. Fits two sprawling adults with 20” pads. While not as secure as FF, fantastic and more lightweight.

Rated 3 out of 5 by from Idea is great but... The idea of this coupler is awesome. However, it doesn't fit my Thermarest pad, let alone two. Material is okay, could be a lot softer. Maybe I'm just used to the softness of my sleeping bag underneath me. Also, it's a bit heavy for the type of hiking I do.

Rated 4 out of 5 by from UTILITARIAN WEIGHT SAVER Cut a full kilo from your total carry weight with this handy item. It basically holds an unzipped bag in place where the down does the most good: on top where it can attain full loft. A good complement to the WM Ponderosa Not cheap.......TIM

Rated 5 out of 5 by from Must have for couple hikers/campers What an awesome purchase. We only use one bag plus this coupler. We are warm all night and comfortable. There is plenty of room for the two of us using the coupler!

Rated 5 out of 5 by from Like two bugs in a rug! Oh, my! I can hardly wait until warmer weather, when I can use this for two with my new Western Mountaineering bag. A great way to use a cold weather bag in the summer months. Works either as a bottom layer or a top layer. Many years ago I had a similar product from England, but I didn't discover this one until just recently. These Western Mountaineering folks know what's important.

Does this coupler work with an REI Joule bag? What kind of zipper is on the coupler?

Asked by: Flying Marmot
Hey there, Thanks for reaching out to us! Did you know my nickname in high school was 'coupler'? JK, it was 'Goldfinger'. Now, while I'm not super familiar with REI bags, I know that this will not work with mummy bags. It'll work with hoodless Western Mountaineering semi-rectangular bags, 2000 model year or later. And that zipper will be a full-length #5 YKK Zipper. Hope this helps you out. Hugsies!!

I own the WM Mightylite and see I would need the 6’6” version. What size sleeping pads would fit in this? My wife and I use 25” rectangular therm-a-rest pads now.

Asked by: Dpsphotos
Hey there, Thanks for reaching out to us! Did you know my nickname in high school was 'mightylite'? Psych. It was 'coupler'. So, with this item, you'll be able to use the same pads that you were using in your regular pads! Shouldn't be any issue at all! Hope this helps you out. Hugsies!

Four questions: 1. Is it enough to use one sleeping bag together with the coupler? 2. Does it matter if your sleeping bag has a right or left side zipper? 3. How wide are the underside sleeves? 4. Does the coupler fit with a WM Terralite?

Asked by: Pernillan
Hiya, thanks for your questions! I hope you are ready for information overload! Here are your answers: 1. It depends on the situation. There are many variables, such as conditions, which bag is used with the coupler, what pads you are using (and whether or not you are using the pads effectively-i.e. not blowing moist air into the valves when the nightly low temperatures are likely to drop below freezing), metabolism, and how warm or cold the two people tend to sleep. 2. The summer coupler is designed to be used with hoodless semi-rectangular bags like the Ponderosa, the Alder and the Mitylite. For these models, there are no left or right hand zippered options, they are all made as left zippered bags but they can be flipped over if someone wants to use them with the zipper on the opposite side since there is no hood. The hooded semi rectangular bags such as the Terralite, Sycamore, Sequoia, Bristlecone, or Cypress can also be opened up and mated to a summer coupler, however, there is going to be more down distributed on the top of any bag which has a hood. (60% of the down will be on top and 40% of the down will be on the bottom). When the bag is flipped over, one side will have more down than the other but you can shift the down around within the bag to even it out. These bags are offered in either a left or a right hand zipper and either will work when the bag is opened up and zipped to a summer coupler. The Bristlecone and Cypress are colder weather bags so they have a block of netting at the side to create separate down chambers for the top and bottom of the bag. In these two models the down distribution cannot be adjusted so one person would have less down above them than the other (and since the bottom of the bag is the side with less down that person would also have a hood over their face when the bag is opened up and mated to a coupler.). Also the zipper lengths on the hooded semi-rectangular bags is slightly different on the bottom zipper than our hoodless semi-rectangular bags so there is a little bit of extra coupler that remains as extra material at each side towards the bottom. 3. The bottom edge measures 24” across each side to the center stitch line. The lower sleeve panel measures 22” across from each side to the center seam. 4. The Terralite can be used with a summer coupler however, as explained in the answer for question #2, the bottom (vislon) zipper length is a little shorter on the hooded semi-rectangular bags than it is on the bags without hoods. This means that there will be a little bit of extra coupler at each side just below where the coil zipper ends and the top of the vislon zipper finishes. Hope this helps!

Will this western mountaineering summer coupler fit a western mountaineering sycamore sleeping bag?  Thank you.

Asked by: Steve
Yes, the Western Mountaineering Sycamore sleeping bag is zip-in compatible with the Summer Coupler.

Will two Medium EXPED 20.5" x 72" x 2.8" SYN MAT 3-D 7 Sleeping Pads fit into this Coupler?

Asked by: TAGISH
Hey there TAGISH, Great question. Two Exped Syn Mat 3D 7s in size medium will work with this coupler. The whole point of this coupler is to make a double sleeping bag out of a single by folding the bag out butterfly-style and double zipping the coupler to it like a bed sheet. Given that set up in combination with a compatible bag, these two pads should work out. Hope that helps!

Will the Exped Hyperlite Duo pad work? It's 41.5"w x 72".

Asked by: dana
Thanks for the question! YES, the Hyperlite Duo will work with the WM Summer Coupler. Since the Coupler will work with two EXPED mats measuring at 20.5 x 72 inches, it will work with one at 41.5 x 72 inches. In addition, both items are semi-rectangular. I hope this info helps!
