Ortovox Westalpen 3L Light vs Rab Latok Mountain GORE-TEX Pro
Choose Westalpen 3L Light if you want a 332 g shell with Dermizax NX construction and large mesh-backed front pockets. Choose Latok Mountain if its reinforced GORE-TEX PRO ePE layout and adjustment suit your use. Rab lists the checked size-M Latok at 407 g.
Based on 36 included owner reviews.
The differences that matter
Ortovox emphasizes a helmet-compatible adjustable hood, large front pockets and merino inserts around the neck and chin. Rab combines 80-denier main and 40-denier secondary fabrics, reinforcing the shoulders and sleeves. These are practical construction choices, rather than proof of a controlled durability ranking.
The listed weights do not provide identical reference information, so treat the gap as context. Try pocket access with a harness and check the hood with your own helmet. Different fabrics and a regular-fit label cannot tell you how either jacket will sit over your insulation.
