Ayacucho Mountain 3L vs Mountain Peak 3L

Based on 64 included owner reviews.
The differences that matter
Mountain Peak lists three outer pockets and two inner pockets, giving you a concrete reason to consider it if you organize gloves and small items in the jacket. Mountain has two hand pockets and an internal zipped pocket, alongside two-way underarm zips.
The own-brand page lists Mountain Peak at 550 g, but a comparable verified weight for Mountain is not available here. We therefore do not call either one lighter. The material change alone also cannot establish which finished jacket will last longer under your pack.

Which should you choose?
Choose Mountain for the hood and articulated layout if its storage is enough. Choose Mountain Peak for the polyamide construction and additional pockets when they are useful. Try reaching the pockets with a waistbelt on, and check the owner fit findings before deciding on a size.
