Epic 10.3
Arctos Packs were designed here in San Luis Obispo for mountain biking, but a growing number of our reviews come from moto riders who found something most backpacks miss: real weight-carrying comfort on your hips, not your shoulders, without the bounce.
FREE YOUR SHOULDERS
Arctos Packs get the weight on your hips, freeing your upper back and shoulders from discomfort and reducing sweat.
ULTRA STABLE
Our super breathable shoulder straps and dual action waist belt cinch the pack to your body AND cinch the pack's contents down so that your pack doesn't move on the roughest rides, without you having to crank any of the straps down super tight.
EASY ACCESS
Huge zippered wing pockets put frequently-needed items at your fingertips. Huge durable YKK zippers and zipper pulls make grabbing stuff with gloved hands easy.
Features
- Fits roughly 5'5" - 6'5". See fit section below for details.

Fit
Our packs typically fit folks between 5'5" and 6'5". If you're near 5'5" and on the slim side (under 150lb), you will probably run out of adjustment room on the shoulder straps. Users slightly over 6'5" may be ok, depending on other dimensions (chest/torso size, etc.). We are happy to send you a free return label if it doesn't fit.
If you're close to the ends of our adjustment range, we have detailed fit videos available to give you the best shot of our packs fitting you.
Note: We are actively developing smaller strap sizes to accommodate those below 5'4", launching late-2026.
