I recently came across this pack (not an affiliate link) by Sierra Designs while at Target, and knew that I had to give it a try. Here are my thoughts and full review, including pros and cons.

I have been searching for a 35-45L backpacking pack for a while now; I was looking in many places such as Waymark, Z Packs, etc. However I just could not bring myself to spend $500 or more on a pack. This one was $40, so I figured that even if it didn’t fit my ultimate goal, it is still a great pack to have on hand.

Summary

For all my people who want the quick overview here are my thoghts:

  • yes it is worth the price
  • well constructed
  • fits all my gear, as an UL backpacker (base weight under 15 lbs)
  • not well suited for the more traditional weight backpacker
  • bear cans with the pack require some extra situating
  • not waterproof: needs a bag liner and rain fly
  • overall do I recommend? yes
  • Capacity: 40L / 2,441 in3
  • Weight: 2 Lbs 9 oz / 1.2 kg
  • Dimensions (L x W x D): 21.3″ x 12.8″ x 9.5″ / 54 x 32.5 x 24 cm

Pack Details

This pack has one main pocket, with a drawstring top and water bladder pocket. I cut, tied, and re-burned the draw sting, as it was longer than needed; I definitely recommend doing this, this way you will not have any excessive string hanging when the pack is closed.

In the brain of the pack (also known as the part that clips over the top) there is a top pocket and small front pocket.

As for straps, there are the the two clips that hold the brain down, featuring a thick bottom part that has room for attachments.

There are 4 loops on the bottom where additional gear can be attached.

The two carry handles are on the bottom front and top back of the pack; and there are the two cinch straps on the sides to compress the contents of your pack.

Finally there is a flat front pocket and two large water bottle pockets.

The back and shoulder straps/ hip belt straps are padded; and the shoulder straps have elastic loops for attachments and a chest strap to distribute weight.

Cons

  • no hip belt pockets
  • may not fit all sizes; I wear a fitted pack size s/m and it fits well for me, if you are not that size, it may be slightly large or small. The best way to see is to try it on in store or be sure that there is a good return policy if you buy online.
  • needs additional bag liner/ rain fly
  • no ice axe/ trekking pole loops; you may need to get creative using or adding loops with this one

Pros

  • lightweight (at approximately 2lbs)
  • VERY well priced at $40
  • spacious inner pocket
  • right size any time for an UL backpacker or for a shorter trip for a traditional backpacker
  • good amount of additional outside pockets, right amount for good organization
  • padded hip belt pockets/ shoulder straps
  • loops on bottom for additional attachments

Closing Thoughts

Overall I am very happy with this pack, it turned out to be perfect for what I need as a light traveler. I have taken it on several smaller trips and am excited to try it out on a longer trips!
