    BMBH DIY underquilt width?

    Looking at picking up a BMBH. If I were going to make a DIY under quilt from a sleeping bag that 36" wide would that be wide enough to work around a BMBH? I am fairly small framed, 5'6 145#
    thanks.

    I find on a bridge hammock, narrower underquilts work better. That is one reason that the Mt. Washington line of quilts are only 42" wide. Some of the underquilts that Grizz makes for his Grizzbridges are only 36" wide. So I say pick a number between those 2 and you should be fine width wise for the BMBH. As for length, that is entirely up to you.

    Cheers

    I'm preparing to make a DIY uq for my BMBH too. The distance between the hanging tabs on the hammock is roughly 42", so anything below that is probably fine hanging-wise.

    Another thing to consids is how far up the side you want the quilt to go. 36" will probably get your back and shoulders fine while flat, but you might lose coverage if you lean up too far on the side or rest your knees on the sides.

    Here are some pics of the 42" wide MW3 ( short/torso ) on a BMBH, shot from inside the occupied hammock.



    For I consider that the sufferings of this present time are not worthy to be compared with the glory that is to be revealed to us....that the creation itself also will be set free from its slavery to corruption into the freedom of the glory of the children of God. For we know that the whole creation groans and suffers the pains of childbirth together until now.

    Guys thanks for all the great post and pictures.

    So here is my plan, let me know what you think. I plan on buying this sleeping bag. (see bellow). It is a 40 degree bag, 65" wide. cutting it in half the long way and using the top part is an top quilt and spraying the bottom with some water replent spray and some suspension to work with the BMBH and using it as a bottom quilt. I guess it would be two pieces at only 32.5" wide. Granted this would be for summer camping, but for under 60 dollars to have both would be a great deal.....if it works. What do you guys think? ... is it crazy?

    I also thought of sewing on a velcro strip when cutting it so I can push it back together to use as a normal sleep bag if I wanted to on occasion.

    That is 9.5" less wide than the JRB MW in the pics above. Looking at the generous coverage supplied by the MW in the pics I supplied ( it comes up several inches above the center top edge of the occupied hammock). You will be reducing that coverage 4.75" on each side. I think you will get by, especially in the summer.

    I think a much greater challenge will be staying draft free with a TQ just 32.5" wide. Most TQs are at least 48" wide, many are 50 plus. But the chance of success will be greater in the BMBH than with other hammocks, IMO. Still, that is pushing it. Are you skinny and do you not move much while sleeping?

    Generally concur with BB58 for summer..... But the concern for TQ tuck applies to back of the shoulder and back side ,outer portions of arms as well, warmth of the UQ...Too Narrow IMHO but hey, give it a try and report out.

    Thanks Guys. It would be a close fit I think. I measure 50" all the way around my arms and chest. The NF bag measures 65" for girth. This would leave approx 4 " tucked at the sides from the DIY TQ and n4" wrapped from the bottom a total of 8" on each side. I guess if I move it could be a problem. Maybe a few small cut pieces of pad for "wings" at the shoulders would do the trick. This would definitely be a summer rig. A long way from summer camping up here in Minnesota, so I will have some time to think about and construct it before I report back!
    thanks.
