Joni Sasich wrote a review of JanSport D2 85 Backpack - 5221cu in on August 9, 2011
I am a 56 year old woman who has been using the original D series Jansport for the last 30+ years. I have put plenty of backcountry miles both on trail and off on this pack and have considered internal packs over the years but just can not part with my D series. I have packed 50 lbs and now about 35-40 lbs...the D series distributes whatever weight you put in it! The waist handles have come in handy plenty - I use them to shift the weight when crossing logs or side hilling or for a break after many miles on the trai or to rest my trekking poles. It is nice to have a free standing pack with individual pockets at camp ...my stuff is organized and always handy. The only drawbacks are: 1. can easily put too much weight in your pack as it is so roomy 2. the external frame can interfere when looking up on a steep slope...e.g. not for technical climbing.
I have to say, I am disappointed in the lower pocket in the new model with the words JANSPORT so vividly displayed...a bit tacky don't you think?
