Can a "reg/left zip" zip together with...

Posted on

Can a "reg/left zip" zip together with another "reg/left zip"? Or do I need to find a "right zip" somewhere else?

Responded on

f,
To zip a pair of Mountain Hardwear Extralamina 20 Sleeping Bags together you will need both left and right side zip bags in complimentary sizes (i.e. reg/left and reg/right, or long/left and long/right).

Way too thin

  • Familiarity: I returned this product before using it

My niece needed a wide 20 degree bag. I thought this looked like a good deal until I got it and saw how thin it was. There is no way it would be comfortable anywhere close to 20 degrees. I am returning it.

Zips fine

After doing some research, I bought this bag because I wanted something warm on cold nights, comfy, roomy, light, and my boyfriend and I wanted bags that were able to mate. He recently retired another bag following many years of use culminating in a long bike tour, and we thought why not get some that zip together, you never know when that will come in handy. I haven't taken my bag on any rigorous trips yet to push the limits of moisture resistance and sub 20F temps, but we both agree that the bag delivers on our expectations- it keeps us warm within the advertised range, it's very comfortable, it's fairly light for a roomier bag, the design of the foot ventilation zippers and hood drawstring are very intuitive and easy to use. After some close examination from both of us following a lot of negative reviews for the zippers, we are confident in the construction and use of zippers on this bag. I'll gladly update this review if any obvious issues come up, but I am very happy with the purchase of this bag and look forward to lots of years of use camping/backpacking/bike touring ahead.

Great bag for the price!

  • Gender: Male
  • Familiarity: I've used it several times

The bag is synthetic so the weight/warmth ratio is really great. First I got the lamina but I traded it in for the super lamina for the extra room. The Super lamina fits much better. I loved this bag so much I bought another one for my girlfriend because they zip together

I don't get all the poor reviews about the zipper, there are three different zippers partially because two bags can be zipped together, but as long as you don't rip into it like a behemoth, the zipper's work great. Especially love the bottom zipper for the feet, it opens up for ventilation for warmer nights.

Comfy, but cold and horrid zipper

  • Gender: Male
  • Familiarity: I've put it through the wringer

I've had the bag for over 2 years now and have had it out in all sorts of weather conditions. It is soft and plenty roomy (I'm 6'3" 200lbs) and it comes with a nice compression sack. The good ends there. The zipper gets stuck constantly and requires an insane amount of babying to get it up and down. While on the West Coast Trail this past summer the zipper got so caught up in the bag that I had no choice but to rip the fabric to get it free- POS. Also, it doesn't sleep anywhere near a comfortable 20. On a late winter trip, sleeping (trying to sleep) in upper 20's was a terrible experience. My feet got so cold I was concerned about frostbite. Wish I'd bought it at Backcountry or REI- it would be returned in a heartbeat.

Two things I love

I have not had the problem of the zipper jamming like the review before, I love how small it packs down and it is nice and roomy for a mummy bag which actually allows me to get some sleep on a trip. I did find its temperature rating was not accurate, I am a bit of a cold sleeper but I needed my icebreaker long johns and my smartwool quarter zip.to get through a couple of nights. all in all I will be taking this bag on the longer trips this year again just because of its size and weight and room, I always have the clothes so dosent really matter the weights there anyhow.

lots of room

Great bag if you are a big guy like me(6'2" 250 lbs). Just like clo said, it does have a bad zipper. Although mine is only a problem on the last 8 inches, the rest runs smooth. Specs say a long is 3 lb 6 oz but my long weighed 2 lb 15 oz on my digital scale. I even checked my scale with a calibration weight and everything was fine. I found others with the same issue on other sites. This bag is warm as I have been down to 24 deg and was toasty.

Comfy bag, Horrible Zipper

Am out shopping for new bag. This one stuffs great, is very soft and comfy. However, huge complaint is the zipper, which is horrible. Two different ExtraLamina bags bought at two different times, and both jam like freight trains. I mean jams bad enough that a kid can't undo them. I love this bag, but when you spend a night with the zipper jammed halfway down. I can say you won't get much sleep. Looking at MontBell and TNF. Both have much more rugged zippers that I couldn't get to jam. I should have known when the UltraLamina jammed in the showroom. My bad. Fool me once ...

Sorry to hear that has happened to you. I have been using this bag for over a year on many trips and never had an issue with the zipper. I actually think hey are nice, sturdy zippers.
