Like a bubble bath. Well, not at all, actually.

Happy for this purchase

  • Gender:Female
  • Familiarity:I've used it once or twice and have initial impressions

I bought this backpack for a 5 day trip. I was able to fit many light weight items in it. I love that it's specially designed for women and that it's adjustable. I loved that I received it in 2 days and that I got a free Toms toothpaste! I would like to buy from this company again soon. I know I'll keep using my backpack. I'm in love with the North Face products.


Great Choice!

  • Familiarity:I've used it several times

A great buy! Bought this backpack right before my first trip to Italy, and I was able to travel comfortably. Not as large as I imagined it to be, but very stretchy to fit all my items in. Also, backcountry staff helped me out immensely by making sure this product got delivered to me right before my big trip. Great product, and a great company!

Is the difference between S/M and M/L size...

Is the difference between S/M and M/L size only in torso length or are there any differences in hip belt and straps as well?

Most backpacks are sized purely off of torso length, and have a standard size of hip belt. I would assume this TNF pack is the same.
