Leave the city, beat the camping crowds.

Spend a night, or a carefully packed weekend, in the woods with everything you need inside Marmot's Graviton 38 Backpack. This pack's Ventilated Airflow Suspension keeps you cool and comfy on the approach, while the Tubular Aluminum Frame ensures stability so your gear doesn't swing with each step. Marmot padded the shoulder straps and waist belt with airmesh for breathable comfort.

The Graviton is a traditional top loader with an extra sleeve and hanging clip for your hydration reservoir. There are two attachments for trekking poles or ice tools. Marmot's pocket configuration for this pack includes a large top lid for maps and much-needed trail essentials, an internal mesh pocket for valuables like keys, and waist belt pockets for energy gels and lip balm.

Perfect For Overnight Trips

  • Familiarity: I've put it through the wringer

This was my first midweight pack, and I gotta say its really nice having something that can haul gear for short trips but does not have the weight of a 70L pack. I got this for doing long day hikes, but was blown away with how much I could comfortably carry. I've even used it for weekend backpacking trips, which definitely overloaded the pack (mainly because the waist belt just wasn't meant to bear that kind of weight) but I absolutely love how well this thing breathes. The air mesh ventilated suspension is legit! Most of the hikes I do are in Utah so it gets really hot and its nice to have a pack that so ventilated. I would recommend it to anyone looking for a pack to do long day trips and smart packed overnights. Any questions, feel free to reach out!

Hi there, can you measure the height of the frame of the bag? As well as the height of the bag with the top removed? I'm looking for something that will work as a carry-on on a plane and I'm afraid this might be a bit tall. Thanks!
