Summary
At just 3.0 lbs with a 60L capacity, the Blaze 60 is the sweet spot for ultralight-curious backpackers who don't want to sacrifice comfort or features. The removable brain and hip belt convert into a fanny pack for day hikes from camp.
Sub-2-pound Dyneema construction is fully waterproof, tear-resistant, and rated to carry 40 lbs — a combination no other ultralight pack matches. The go-to choice for serious thru-hikers on the PCT, AT, and beyond.
Pros
- Only 3.0 lbs measured weight with 60L capacity — best weight-to-volume ratio in its class
- Supports loads up to 50 lbs despite ultralight construction
- Removable brain and hip belt combine into a fanny pack for day hikes
- Nine compression straps handle variable loads; breathable back panel and front access zipper
- Under 2 lbs (1 lb 13.7 oz) with Dyneema fabric that's fully waterproof and tear-resistant
- Rated to carry loads up to 40 lbs — far more than most ultralight packs (typically 30-35 lbs)
- Removable aluminum stays, foam back panel, and wide supportive hip belt for load transfer
- Available in 40L, 55L, and 70L capacities
Cons
- Small buckles are difficult to operate with gloves in cold weather
- Less feature-rich than the Osprey Atmos AG LT (fewer pockets, less adjustability)
- Not as comfortable as the Atmos AG LT for very heavy loads
- Expensive at $399 — nearly twice the cost of the REI Flash 55
- Minimal organization: lidless design with streamlined storage may shock traditional backpackers
- Dyneema back panel offers poor ventilation — gets sweaty in hot climates
Our take
This is the pack I'd recommend to anyone who wants to go lighter without going full cottage-brand ultralight. It carries up to 50 lbs comfortably at 3 lbs — that combination is genuinely rare.
If you're logging serious miles and want the lightest pack that won't fall apart, the Southwest 55 is the answer. It's expensive and minimal, but Dyneema's strength-to-weight ratio is in a class of its own.
