Helpful Positive Review

As a liner....

by Shaft, from TX, United States Updated on January 15, 2022
This bag completed a secondary sleep system, the first being my MSS. I think this is a better system as I am using all ALPS bags. This like the Dagger are capable of keeping you warm into the teens F. When I combined them into a complete system (including a non-ALPS bivy bag) it was the ultimate in keeping the chill out!
Pros:
  • None
Cons:
  • method of connecting the zips
Best Used for:
  • used as outer liner
Would recommend: Yes
