Engineered for the Long Trail

The Trail Runner Pack 32L was born from a single question: how light can a full-featured pack get without sacrificing durability? After three years of prototyping and over 2,000 miles of trail testing, we arrived at 680 grams of pure alpine capability.

The roll-top closure system provides infinite volume adjustment while maintaining a watertight seal rated to IPX4. Inside, a removable aluminum stay gives the pack structure under load, while the 3D air mesh back panel keeps you cool during high-output efforts. The hydration routing accommodates reservoirs up to 3 liters, with a magnetic hose clip integrated into the shoulder strap.

Every detail serves a purpose. The side mesh pockets stretch to hold 1-liter bottles securely. The hip belt is padded enough for comfort on long approaches but removable for scrambling or when you want to shave another 60 grams. The front shove-it pocket holds a rain shell or wet layers, and the dual ice axe loops are reinforced for real alpine use, not just trail-runner decoration.

Size Guide

Measure your torso length from the C7 vertebra (base of neck) to the top of your hip bones. When in doubt, size up for longer trips and size down for fast-and-light missions.

5/5

Perfect for ultralight thru-hiking

By Morgan R. Verified Buyer

Carried this through 200 miles of the PCT. The roll-top closure kept everything dry during 3 days of rain. At 680g it's lighter than most frameless packs but the removable aluminum stay gives real structure. I kept the hip belt for the first 100 miles, then removed it for the more runnable sections. Brilliantly versatile design.

Great pack, wish the hip belt were wider

By Casey L.

Love the materials and design. Hydration routing is clever. Only complaint is the hip belt could distribute weight better on 25+ lb loads. Perfect for anything under 20 lbs. The side pockets hold my 1-liter bottles without any bounce, and the roll-top is actually waterproof, not just water-resistant.

5/5

Best fast-pack I've found

By Jamie W.

Third Alpenglow product I've bought. The attention to detail is remarkable — every pocket, strap, and zipper feels intentional. Nothing is there for marketing purposes. I use this for day trips and overnights in the Sierra, and it handles both perfectly. The aluminum stay comes out in seconds for summit pushes.
