    Perfect bag
  

*by E***D on Reviewed in the United States on 20 October 2024*

Great 2.5 season bag.  I own 3 of these.  They pack small and when camping as a family with everything you need size matters.  My original Kelly is going on almost 10 years strong with plenty of life left.  I bought these for my kids and they like them

### ⭐⭐⭐⭐⭐

*by T***K on Reviewed in the United States on 17 September 2021*

I've used this bag heavily the past few weeks in August for backpacking in the Sierra Nevada. It keeps me plenty warm while also wearing a light base layer. Well made Kelty product. Fantastic value
