I hope this helps others who are trying to go frameless or perhaps this is well known.
My main reason for going to frameless is because I do not have much in the way of hips. Have tried several framed backpacks and they all will slip unless I tighten the hip belt a lot – which then restricts my breathing a lot. Which then results in getting breathless when climbing and needing to stop or take more breaks than necessary etc. The problem gets worse by week 2 of a month long hike as you lose some weight and the slippage is more pronounced. And the more you have to tighten to keep the backpack on your hips. Loosening the hip belt will then put the entire load on your shoulders and most of the framed backpacks do not have good shoulder straps.
During my PCT-Washington section hike this year, I used to loosen the hipbelt on climbs in spite of the load on the shoulders in order to climb better – I had my HMG 3400 which has skinny shoulder straps. In 2018 on the JMT, I had Sierra Designs Flex Capacitor and I had the same issues. Though it had not struck me back then to loosen the hip belt while climbing.
I have a MLD Prophet which has excellent shoulder straps. I do not have a hip belt on this pack. I tried to carry 22 to 23 lbs on the shoulders and it carries very well for me. I can breathe excellently while climbing and it is a joy to hike. However, I need to carry more than 23 lbs.
My base weight is around 12 lbs. With 6 days of food and 3 liters of water, my total load pack weight comes to 27 lbs. This will be very difficult to carry in a frameless for most. Some are able to carry those weights. Not me. So, what I do is carry the remaining weight in my fanny pack. The fanny pack I was looking for needed to be able to carry 2 water bottles. I tried several – Sierra Designs recently released two models (the water bottle mesh is too shallow), Patagonia has a 5 liter one with two water bottle holders (the mesh for the water bottles is too tight). The one I like the best is from Amazon – which has a deep/tall mesh water bottle holders. I carry two 20 oz Gatorade bottles in the fanny pack along with 2 lbs of my base weight – Steripen, head lamp, stakes, spoon, woolen cap, neck gaiter, hand soap, gloves, my electronics like battery bank etc. Almost 4.5 lbs. I find that the 4.5 lbs doesn’t restrict my breathing one bit. Carrying 27 lbs on the hips is much more difficult than carrying 4.5 lbs. The fanny pack itself is 1 lb or so. So, totally 5.5 lbs on hips which is a breeze. 22 lbs on shoulder is also perfectly fine. Why 3 liters? Because I plan to do the Colorado trail this summer and there is a 22 mile section without water and I wanted to make sure that I can carry Yiu ca 3 liters at least.
On the MLD Prophet, since I am not able to reach the water pockets – this is what I did. I added two SWD water mesh pockets. Luckily, the Prophet has several attachment points. You can see the two gatorade bottles. Smart water will also fit easily of course. You can easily access these water bottles.

The fanny pack looks like this:

I keep the fanny pack in the front. Not having the hip belt makes it easier to carry the fanny pack. Though I have seen folks with framed backpack with hip belt carrying a fanny pack as well – they make the two hip belts work somehow. I tried it and didn’t like it.
I love the above setup very well. I hope to carry this on my CT next year. I think in general, a 27 lbs on hips is not as comfortable as a 22 lbs on shoulder and 5.5 lbs or so on your hips. Try it. You will be pleasantly surprised.
I think if I had a pack that covered 3/4th of my back that didn’t occupy my lumbar area, then I could place the fanny pack in the lumbar area. I could always keep the fanny pack in the front so that my lower back gets some ventilation as well. You could keep the fanny pack on your back while climbing and then move it to the front while descending to air out your lower back etc. Lots of possibilities.
I do not use any virtual frame with a pad etc as I don’t use the hip belt. I don’t have any issues with the pack on my back – nothing pointy.
I thought I will share my experiences with frameless pack and how I am trying to make it work in spite of not having a ultralight base weight etc. I carry 4 20 oz Gatorade bottles plus a half a liter which makes it 3 liters – not shown everything in the pictures.
