The Burn 38L | 2300 CI has been used by many FKT (fastest know time) record setting thru-hikers including three time Triple Crowner Lint Bunting.

FKT, or “Fastest Known Time,” is the fastest time hikers, bikers, runners, and other endurance athletes have completed a certain trail or distance. The ethos behind FKT is self-reliance. The FKT concept includes personal FKT’s – Your Own Personal Goal. To achieve a personal FKT gear is trimmed to the minimum and knowledge and training become key factors; movement is calculated to be as efficient as possible regardless of your overall speed or daily mileage.

The Burn 38L | 2300 CI is here to help you meet your own FKT goals – ultralight, ultra-strong, and optimized in every way to make you faster, lighter, stronger.

“Double thumbs up. Since 2010, I have owned two Burns. Each has at least 8,000 miles on it. I’ve yet to have any tears to the body of either pack.” – CAM HONAN

NOTE: Burns ordered after 6/10/2018 will have the larger 2.75″ wide straps and padded hip belt wings.

“The Burn really is an exceptionally well thought out, well made, bomber little pack. And as with all MLD products, the quality and attention to detail is second to none and a strong reminder why MLD is at the top of cottage manufactured ultralight gear.” UL GEAR BLOG


• NEW FOR 2018: Curved Side Panels: A slight curve from the waist to the shoulders moves the load closer to the upper back for more comfort. This also creates a slightly larger main compartment higher in the pack that helps load control by moving the heavier and higher packed gear higher to reduces shoulder stress.
• S-shaped unisex comfort shoulder straps are 2.75″ wide X 0.8″ thick and are SuperWick mesh lined with full-length highest quality 1/2″ thick EVA foam padding. Our shoulder straps are thicker and wider than most lightweight packs. Full length daisy chain accepts all Shoulder Strap Pouches.
• Hybrid Mesh/Dyneema X Side and Rear Pockets. The leading edge of the side pockets are Dyneema X to prevent snagging when moving through the bush. The lower 5″ of the rear pocket is Dyneema X to prevent abrasion from sharp contents or butt sliding accidents. The 4 oz sq/yd open hole non-stretch water and drains fast to allow contents to dry faster than a tight stretch mesh or solid fabric. Dyneema X elastic top sleeves for long term Durability and elastic replacement.
• Padded lightweight Dyneema X hip-belt wings with 1″ webbing and lightweight buckle. Optional removable Hip Pocket can be attached.
• Large, slanted mesh side pockets are deep enough for a 2 L Platypus. Top bungee sleeves of Dyneema X for long term durability vs. cheaper style wrapped tops of uncovered elastic bands. Pocket adjusts by pulling the bungee closed through the cord lock. Bungee is 1/8″ thick 40 below rated elastic in a nylon sheath style bungee. Many lower priced packs simply bind over the top of the raw mesh with regular garment type elastic that loses it’s stretch in a few years and does not do well in deep cold weather.
• 12 bungee attachment web loops with 7 mm glide rings for multiple attachment points for load compression and gear lashing. A short loop of 3 mm line can be attached to the lower loops for trekking pole and ice ax attachment
• Left shoulder hydration ports

• Torso lengths on MLD packs are measured from the bottom of the pack below the waist belt wings to the point where the shoulder straps attach to the pack.
• 95% of MLD packs users do best to go by our height guidelines
• Different pack makers and outdoor stores measure for torso length differently AND frameless pack are measured and fit differently than fully framed packs with large hip belts. DO NOT go to your local outdoor store (REI etc…) and “get pack fitted” and then select a size/length based on that measurement; it will be wrong!
• Use our height guide! If you need help deciding the right size – Please feel free to give us a call. (Please don’t order multiple sizes as a guess!)
• Test Fit You Pack Indoors after Receiving it – We are happy to exchange for different size or refund new/unused packs.
• If In Doubt – SIZE UP!

1 review for BURN 38L | 2300 CI

  1. Rated 5 out of 5


    I’ve been carrying MLD packs for many years now. Starting with the Exodus, then the Prophet, and have now used the Burn on 4 thru hikes. After removing the hip belt and sternum strap, I get it down to a sleek 11 ounces. Perfect for my 6.5 pound baseweight. It’s hard to beat the simplicity and efficiency of the Burn, if your kit is light and compact enough to work with it. The craftsmanship is top notch, and I get 2 thru hikes out of a pack before it’s worn out…so about 5000 miles from an 11 ounce pack. Pretty awesome.

    The mesh pockets on either side hold a Smartwater bottle well, and by loosening the shoulder straps slightly I can easily reach them on the go. On the rear of the pack, the large mesh pocket is great for storing odds-n-ends, or shove your wet tarp inside so it can dry as you hike. The top closure system is simple and functional…just what I want in a thru hiking pack. No zippers to break, no “brain” pocket to get in the way, just a couple beefy shoulder straps attached to a rucksack with mesh pockets around the sides. It’s the simplicity that makes this pack shine. I drop a closed cell foam pad (torso length) against the back to provide some cushion and rigidity, then drop in a trash compactor bag (for waterproofing) and fill it with my gear. I’ve carried this pack on the Pacific Crest, Appalachian and Continental Divide Trails, so it’ll take whatever you dish at it. Leaving town with a 4 day resupply and 5 liters of water is possible, although you may appreciate the hip belt for loads that heavy!

    If you’re not sure all your gear will fit into the Burn, perhaps try the Prophet, since it’s also a fantastic pack. But if you have a very low base weight and wanna experience the elation of cruising down the trail with what looks like a child’s pack on your back, get the Burn.
