If you’ve ever finished a long day on the trail with aching shoulders and a sore lower back, you know that every ounce in your pack matters. Transitioning to an ultralight (UL) backpack is one of the most effective ways to drop your “base weight.” Traditional expedition packs can weigh 5–6 lbs empty, while a high-tech UL pack weighs as little as 1.5–2 lbs.
The industry has mastered the use of Dyneema (DCF) and Ultra fabrics—materials that are stronger than steel but light enough to float. Here are the top 5 ultralight backpacks on Amazon and specialized retailers to help you fly up the trail.
1. Best Overall: Osprey Exos 58 / Eja 58
Osprey managed to bring ultralight performance to the mainstream. The Exos (and the women’s-specific Eja) is the perfect balance between weight savings and a comfortable carry.
-
Weight: 2.8 lbs (1.27 kg).
-
Key Feature: AirSpeed Suspension. A tensioned mesh back panel that keeps the pack off your back for maximum airflow.
-
Why We Like It: Unlike many “frameless” UL packs, the Exos has a peripheral frame that can comfortably carry up to 35 lbs. It’s the ideal “gateway” pack for those moving toward an ultralight setup.

-
Key Feature: FreeFloat Hipbelt. The hip belt panels rotate and flex with the natural movements of your body, preventing chafing.

3 Rules for Switching to an Ultralight Pack
-
Pack the Pack Last: Never buy an ultralight pack first. You must ensure your Ultralight Sleeping Bag and 1-Person Tent fit inside and that your total “base weight” is under 15–20 lbs. UL packs lack the heavy frames needed to carry 50 lbs comfortably.
-
Understand “Frameless” vs. “Internal Frame”: Frameless packs (like the most extreme UL models) require you to use your sleeping pad as a “virtual frame” inside. If you are new to UL, start with an internal frame pack like the Osprey Exos.
-
Use Dry Bags: Even “waterproof” packs have seams. Always use Lightweight Dry Sacks for your electronics and down sleeping bag to be 100% safe.
FAQ: Ultralight Backpacking
Q: Are ultralight packs less durable?
A: Generally, yes. They use thinner fabrics to save weight. You have to be more careful about setting them down on sharp rocks or dragging them through thick brush. However, fabrics like Ultra and Dyneema are surprisingly tough.
Q: How do I measure my size?
A: Don’t go by your height! You need to measure your torso length (from the C7 vertebra to the top of your hips). Most premium packs like Osprey and Gregory come in multiple sizes based on this measurement.
Final Thoughts
If you want the best all-around comfort and ventilation, go with the Osprey Exos 58. If you are a hardcore minimalist who wants a waterproof tank, the Hyperlite Southwest is the gold standard. For those on a budget, you simply cannot beat the Granite Gear Crown3.
