We spent over a year designing, refining and testing the James River Bridge Ultralight hammock to ensure it was the most comfortable and lightest bridge hammock that could support up to 250 pounds.

The hammock body is symmetrical and uses two different size spreader bars. The longer bar is for the head end and opens up more shoulder room. The smaller bar is for the foot end and reduces knee hyper extension.

Ultralight Hammock body and secondary lines 9.1 oz
Spreader Bars 9.2 oz
Included Storage bag .2 oz

Packed 6″ x 5″ x  12″

Fabric: Hexon 1.6 Dark Olive

Suspension Options:

No Suspension – Use a suspension you already have or DIY your own suspension solution.  The secondary dog bones  are still in place so just attach your chosen suspension to the ends of the dog-bones and you are ready to hang.

Hammock End Straps and Tri-Glide Set -Ultra-light hammock suspension set. No knots or lashings are required. As simple to attach the hammock to each tree as fastening a belt. Position the tri-glide buckle on the strap. Wrap the running end around the tree and thread the running end through one side of the tri-glide buckle. Adjust to center the hammock between the trees. Then thread the running end through the second half of the tri-glide buckle.

Two 10′ long, 1 inch wide, 700 pound, polypropylene web straps with 1.5 inch loops in one end and two JRB Tri-Glides. Each strap weighs 2.1 oz. Each tri-glide weighs 0.3 oz. Total weight for the set is 4.8 oz.

CAUTION: The aluminum spreader bars that come with the Bear Mountain Bridge Hammock are intended to withstand the compression force along their long axis caused by the suspension straps when the hammock is loaded. Lateral stresses on the spreader bars, particularly when they are under compression, will cause the bars to fail and bend, ruining the spreader bars. DO NOT try to adjust your body position in the hammock by pulling on the spreader bars. Instead grab the sides of the hammock to adjust your body position. Jacks ‘R’ Better does not recommend hanging packs or other gear from the spreader bar itself as this places unnecessary stress on the spreader bar.

    Wow. Just wow. I love this hammock. A true flat lay bridge and ul. I’m speechless. I just got it, testing it out and just don’t want to pack it up. This is amazing.

    The short version: either the best hammock, or tied with one or two other hammocks for best, that I have used, based on my preferences.

    I am a long time fan of JRB bridge hammocks, started with the original(the one with the removable NON zippered net and pad pocket) back about 2007 or so(still use that one on occasion). I also have the JRB model they call the UL, with zippered net, single layer, also another brand of bridge and numerous gathered end hammocks. This James River has quickly become one of my all time favs. Who knows, it might be my overall favorite, but for me several different hammocks have their pros and cons, including the non bridge hammocks, so it is difficult for me to say that any one hammock is hands down best in all areas, or even over all best. But, this James River sure does get reached for a lot lately, seems like I am reaching for it to take to the woods more often than any of my other hammocks lately.

    Compared to another high quality, well known brand of bridge hammock, I find the two quite similar in over all comfort. Both have the typical benefits of ALL bridge hammocks: zero calf ridge or knee extension, every time. Moth have about the same amount of shoulder room or so it seems to me(the other brand probably has a bit more room due to wider bars)

    The advantages I find with this hammock over other bridges I have tried are:
    1: it is the lightest bridge I have used by far(9 oz, 18 oz with the bars). But, my other popular brand has a pad pocket, so naturally it is going to weigh more. Still, the other brand’s lightest no net single layer weighs 11.25 oz, plus bars at 12 oz= 23.25 oz, plus suspension, with a 200 lb wt limit. The double layer weighs several oz more, with a 250 lb wt limit. So, the JRB at 18 oz with a 250 lb limit is quite impressive.

    2: The JRB does not require as much distance between the trees as does the other brand. It appears to me it requires between 1 and 2 feet less(closer to 2 ft less, I think). That might not seem very important. And it is probably not. But, it is amazing how often I find a place I want to hang, and then the trees are not far enough apart with the other hammock. So, I appreciate the shorter distance, though it is still more than most of my gathered end hammocks and my older JRB BMBHs.
    3: The other brand has head end bars that are 40.5” wide. It has a removable center section that reduces width by several inches in case you want more stability. I have often used it that way. The JRBs head end bars are about 37.25”. This will lead to less width available in the shoulders. But as a broad shouldered guy, I find plenty of room in the JRB. I have been going back and forth between the 40.5” bars and the JRB 37.5”, and I can’t find any noticeable comfort difference. But, bars that are less wide lead to less contact with the tarp, and an ability to pitch the tarp in a more narrow storm pitch when needed. So, again, pros and cons.

    4: I have not measured it, but it seems to me the JRB is wider in the middle. This gives me more room for my knees when drawing my knees up for fetal. Less tendency for my knees to end up on the stiff edges of the bridge.

    5: As has been my experience with the previous JRB bridge hammocks, my JRB quilts-either short or full length-have worked perfectly every time. There is little need for finding the perfect adjustment for the quilt. I never have any cold spots, head to heel. I can’t say that this is an advantage compared to the other brand, I have found all bridges easier to insulate. But it is excellent, about as good as things can get with an UQ.

    6: The JRB is a bit deeper. Pros and cons. For me that is a pro, as I like to lay back into the sides of the hammock while partially on my side. The deeper hammock feels safer when I do that. I still have all the view I need, I can see out the sides well enough. As it is UL and has no pad pocket, the extra depth seems to help it work better with a pad simply laid inside the single layer hammock. It made me want to experiment with my old Speer Segmented Pad Extender, which worked great!

    That is all I can think of right now for the pros and cons of these two hammocks. But, I continue to be amazed at how light weight this bridge hammock is. And it is either my most comfy hammock, or at least tied for most comfy with my best bridge and gathered end hammocks. But the weight, even with spreader bars, wow! I have plenty of gathered end hammocks, that weigh more even without the spreader bars added weight. Of course, I imagine you could rig up some hiking poles as spreader bars to save even more weight. But I have never done that. I highly recommend this hammock, especially for some one who wants a very lightweight bridge hammock.
