The Montane Halogen 25 is a lightweight, extremely tough and versatile day pack with a comfortable ZephyrFX ventilation back system. Designed for all season mountain use. 

Montane says:

The Halogen 25 is the go-to, multi-activity, all season, technical mountain day pack. Designed to perform on a harsh Scottish winter’s day, the tough but light RAPTOR Geo fabric will resist rock, snow and ice whilst the Montane ‘Tool Anchor’ system allows fast and secure axe attachment. Equally on summer Alpine trails the shell friendly ZephyrFX back system offers fantastic ventilation and airflow to keep you cool whilst remaining close to your back for superior load carry support and comfort. Combined with its multiple storage options including the innovative side Montane ‘Baguette pocket’ the Halogen 25 is a lightweight, extremely tough and amazingly versatile mountain day pack for technical multi-activity enthusiasts.

Montane's Halogen 25 Litre Rucksack replaces the old Cobra 25. Now you might just expect a few updates considering it's still designed for multi-activity enthusiasts but really it's a whole new pack, and a better one at that!

This versatile pack is made of tough yet lightweight material that doesn’t add bulk so won't slow you down. In fact the tough 210 denier Raptor Geo and Endurance fabrics will protect your gear even in cold, wet and icy conditions. The packs also great for warmer environments as the ZephyrFX back system and Contact Mesh back panel will provide the essential ventilation and comfort you need on those hot days.

There's plenty of features but we particularly like that is has a multi pocket configuration for versatile storage options including the innovative baguette pocket on the side of the pack and a stowable tool anchor with an alpine safe sleeve for securing a climbing/walking axe.

The hipbelt is decent for a pack of just 25 Litres this will enable it to carry heavier loads with ease.
