Why We Like The Marmot Kompressor 12L Daypack

Slotted as a clever lightweight option within the Marmot line, the Kompressor 12L Daypack is one of our go-tos for travel and spontaneous hikes thanks to its packable design. The whole backpack zips into a self-stowing internal pocket, packing down to about the size of a 1L water bottle. This makes it perfect for chucking in our suitcase and busting out for day hikes once we get to our travel destination.


  • Compact day pack perfect for hiking and travel use
  • 12L volume easily stores a day’s worth of gear
  • Dual side pockets keep our hydration close at hand
  • Side compression straps consolidate our belongings
  • External webbing chain to clip additional gear to the exterior
  • Self-stowing internal pocket makes it easy to bring along

Poorly designed

This pack is quite small (nice size for running but way too small for a day/commuter pack). Narrow opening so it’s tough to get things in and out. Top flap is tiny and not functional - will not keep rain out. No zipper pockets, interior pockets, key holders or other handy features. It’s pretty comfortable to wear, nylon is durable, external mesh bottle pockets are spacious. I would not recommend, mainly b/c of the ridiculousness of the top closure.

Nice day pack

Small pack for day trips. To strappy- lots of strings and other loops. Almost too many. Draw string top to s not good for quick access

Surprisingly BIG!

[This review was collected as part of a promotion.] This pack is perfect for light daily adventures. I am not small, and this pack provided cinch straps that were more than long enough, a semi-rigid frame sheet, side pockets which can hold regular water bottles, and enough interior space to hold a rain jacket, lunch, and small necessities, What more could you want?

Great mulit-use day pack

I take this bag to the beach, hiking, travelling, snowboarding and any general day adventure. I love all the compartments, it's ability to compress or expand and the comfort of the straps.
