Thank you so much for asking for input on a women's backpack. I have spent the last month searching in vain for a new frameless pack. At 4'8" and 115 lb. it has so far been impossible to find a pack to fit. I currently (and very successfully) use an old GoLite Breeze, but wanted something with just a bit more volume for solo extended trips in cold weather to accomodate a slightly bulkier colder degree sleeping bag, a heavier coat, and a bit more food.
I, too, want to reiterate that a woman backpacking without a partner to share the load carries just as much gear as a man and needs just as much volume (maybe more since men do not carry feminine protection). Make the bag the same larger volume but shape it a bit shorter and wider (our hip bones are broader and can carry something wider).
The shoulder straps should be attached closer together, but
be shaped more narrow and curve around the neck before curving back in towards the chest. Many of the packs I tried on had straps that were so wide they cut painfully into my neck or were attached so far apart they cut into my upper arm and cut off blood flow to my lower arm (a very weird, tingly and painful feeling).
For those ladies that like a sternum strap, could you make it ride higher, above those bumps that men don't have?. I don't currently use one, but when trying on packs I learned that there's nothing more uncomfortable (or unattractive) than being flattened :-)
It would be great if the bag had very deep pockets on all three sides to hold my water filtration system and water, trekking poles, tent poles and stakes, and a wet fly (remember, as a solo hiker, I have to carry my entire tent). I like to carry the wet or dirty stuff on the outside without lashing everything on.
A narrow only slightly padded hip belt would be nice. Some packs I tried on had hip belt pads so wide they didn't fit comfortabley between my hip bones and rib cage. Many women carry enough of our own padding on our hips…we really don't need too much more.
Oh yes, I agree with the others…absolutely no pink or purple packs! I have no desire to look like a six-year-old girl in the woods. I prefer earthy colors but not black. Black makes the inside of the bag too difficult to see into.
I do not need a lot of straps to compress the bag (except one for the bag's top opening) to make it smaller. My bag is always full for a backpack trip. I use my small daypack for day hikes, not a compressed big bag.
Now, if only you could design this dream bag in time for my upcoming Thanksgiving backpacking trip! However, I look forward to checking your site for new designs in the future.
Thanks for listening.
