But if your base weight was 30 pounds and you added 60 pounds of food, you'd be lugging 90 pounds instead of 75. 90 sounds a lot worse then 75
Of course time of year and location have a big impact on base weight. The colder and stormier the season the heavier the pack.
From other posts, I believe "FromNH" is planning a thru hike.
28 pounds "fully loaded" is a pretty good weight for an early spring load. Although he doesn't say how much food and water are included. Which is why we quote base weight.
