Internal Frame Ski Backpacks

Consider your main activity:

• Hiking: Compatible with hydration reservoirs; some have straps or loops to attach trekking poles or other gear.
• Running: Designed to limit bounce; compatible with water bottles or hydration reservoirs.
• Climbing: Slim profile with abrasion-resistant reinforcements.
• Traveling: Has compartments for easy organization; many meet carry-on size requirements.

How much gear will you carry?

• 20L or less: Ideal for short runs, day hikes or quick outings.
• 21–35L: The sweet spot for hiking and travel.
• 36–50L: Best for extended trips or adventures requiring more gear or clothing.

Find the right fit:

• Daypacks are available in a range of sizes.

• Check your torso length and waist against the brand's size chart for the best fit.
• Many packs feature adjustable torso lengths to fine-tune your fit.

Choose a pant fit

• Standard: consistent width from top to bottom
• Slim: tighter to the leg
• Relaxed or wider: fits loosely throughout the thighs, knees and calves

What material do you prefer?

• Synthetic
• Polyester: affordable, stretchy, doesn't wrinkle
• Nylon: durable, abrasion-resistant, less stretch
• Spandex: stretchy, moves easily, less breathable
• Natural fibers
• Cotton: durable, breathable, dries slowly
• Wool: stretchy, durable, odor-resistant, pricier
• Hemp: durable, renewable, can feel rougher

Consider additional features like:

• Moisture wicking: moves moisture (namely, sweat) to the outer surface while also drying quickly
• Pockets: help carry items you want to have accessible
• Sun-protective fabric: a higher UPF rating provides better sun protection
• Convertible: can be worn full-length or as shorts
• Insect repellent: pants treated with insect-repellent coatings can help keep pests off
