Shopping for a new bag is no easy task, at least not…

Rating: rated 5 of 5 stars
Price Paid: Well worth it

Shopping for a new bag is no easy task, at least not for me. Many hours were spent reading reviews and going to countless stores to try on various packs. Looking at all the features and comparing stats was turning into another hobby. Needless to say I found what I was looking for in the Flatiron 38.

My interest in this company came from an ad in the back of Backpacker Magazine and then following the link. After searching their website and gaining a real interest in the gear, I wanted to have a look first hand.

Currently there aren't any national retailers that carry this line, so I called them directly. Speaking with Jeff Popp (Pres./founder) put all of my concerns aside. This is a small American company that has put all their effort into packs and pack accessories, not a large conglomerate that put together a backpack division. Good people with good customer service goes a long way in my book.

The return policy is what sold me; If you don't like it, send it back, they'll pay the postage. So what's the harm of trying? 

You will not find a list of the pack features here, the website holds all of that info. Take a look though, it is certainly worth it. I would just like to mention a few things that really drew my attention.

  • The bag's suspension, fit, and durability are the same you find on larger packs. Most smaller packs lack the backbone of a 50L or larger.
  • Not only is the bottom of the bag hardcore 840 Cordura, but also the bottom of the hip belt. Something commonly overlooked but also a very common wear spot when putting your bag down.
  • Really easy to dial in proper fit with Rip N Pull adjustable harness.
  • Drain holes at bottom of bottle holders. This is handy when you have a sweaty bottle and don't want to soak your pack.

It took me one day on the trail with this pack to find a point of comfort that I haven't found with another bag. At the end of the second day (mile 18) I was actually astounded when I forgot that the pack was on my back. Not sure if I was trail drunk or something, but thats never happened before, especially not with 25lbs.

One more thing, check out the Compression Stackers. Trailspace doesn't have them listed, but they are a brilliant innovation. A compression bag that is actually the shape of your bag. No more wasted space in the pack. Forget those little holes left by all the round bags you have, grab one of these. Mine fits perfectly in the bottom of my bag with room for my tent poles inside.

Manufacturer's Description

The Flatiron is the smallest pack in our Expedition Series and this versatile pack is intended for quick and light backpacking. Though it is a small expedition pack, it is not small on features. We thought it should still be built with the comfort, adjustability and features of a larger pack.

The Flatiron maintains all the right stuff to set itself apart from all other packs in this size range. To improve access to your gear, we put a long vertical water-resistant zipper on the front of the pack and 2 large stretch pockets on the each side for stashing those on trail essentials. It has a sturdy single aluminum stay/HDPE frame system, ventilated backpanel, dual-pivoting hipbelt and plenty more features that make it unrivaled by all other small and light hiking packs out there. For ultimate versatility, the aluminum stay can be easily removed without even opening the pack for more mobility while scrambling.

Retailers' Descriptions

Here's what other sites are saying:

MHM's Flatiron 42 Backpack is a slightly larger version of its well-received Flatiron 38 pack. It may have seemed impossible to make that pack more versatile and functional than it already was, but this update seems to have pulled that feat off. The addition of a little more space makes this an ideal pack for overnight trips or more, if you pack right. Stuff it full of all the gear you need; its tough materials and smart construction can take it, and the supremely comfortable suspension enables you to carry it in comfort.
