Top Pack Cover

Sea to Summit Ultra-Sil Pack Cover

user rating: 5 of 5 (4 reviews)

The Sea to Summit pack cover is a lightweight and weather resistant pack cover that does a good job in keeping the pack dry. My main use of this item so far has been on a 30-day through-hike on the John Muir Trail where I experienced rain on 10 of the 30 days. The cover got a good amount of use on this trip with lots of "putting it on, taking it off" each time I stopped. Even so, it did its job well and stood up to the rigors of the trail.

Reasons to Buy

  • Lightweight
  • Weather resistant
  • Durable (for what it is)
  • Green color blends in well in the forest

Reasons to Avoid

  • Expensive
  • Heavier than some of the (makeshift) alternatives

There is some disagreement about whether a pack cover is worthwhile or necessary. Some prefer to use trash bags or other waterproof materials to wrap around their packs to keep them dry in inclement weather. While there are advantages to that approach, there is something to be said for using a purpose-built piece of gear. Some advantages of using the Sea to Summit pack cover in lieu of a plastic bag or other material include: more durable than a plastic bag or other light material includes an elasticized trip around the edges to hold the cover on the pack includes a snap straps to go around the pack includes its own micro stuff sack for compact storage On the flip side: it's heavier than some of the alternatives at 4.6 oz (including the attached...

Top Pack Duffel

Patagonia Black Hole Duffel

user rating: 5 of 5 (3 reviews)

Patagonia's Black Hole Duffel line has 4 sizes, 45L, 60L, 90L and 120L. All are made from a durable water resistant fabric which can take a beating. I have the 60L size which is perfect for hauling around a ton of gear while still being carry-on size.

Reasons to Buy

  • Durable material
  • Shoulder straps
  • Carry-on size

Likes Size/Shape: The 60L duffel is just within carry-on size limits. With a little coaxing, I've gotten it to fit into even the smaller overhead compartments. For carrying gear on a plane, a duffel bag has advantages over a backpack in that it doesn't have any hard panels that can't be compressed. Also, a rectangular shape can hold more volume than a backpack which is generally taller and skinner with a rounded top. Finally, the rectangular shape is easily stacked versus a cylindrical shape like the North Face Base Camp Duffel.

Pack Duffel

The North Face Base Camp Duffel

user rating: 4.5 of 5 (5 reviews)

My size small base camp duffel is a favorite for short work trips and toting small amounts of extra gear to and from a trailhead. It is built to withstand harsh punishment, easy to carry, and easy to access the interior contents. Cost is the only negative.

Reasons to Buy

  • Durability
  • Good opening
  • Good shoulder straps—carries well
  • Handles and straps

Reasons to Avoid

  • Pricy

Available from carry-on size to trek-swallowing massive, the base camp duffel might be the most indestructible and comfortable way to get your stuff from one place to the other. Mine is a size small, and I use it primarily for air travel, national and international, and for storing extra stuff to toss into the back of the car for a hiking trip. Mine is about five years old. What makes this such a great bag? MATERIALS AND CONSTRUCTION The bag itself is pretty simple—one D shaped zipper opening, super durable handles, straps and materials, very usable shoulder straps for getting this through airports or carrying to a remote bus stop.

Top Dry Bag / Compression Sack

Sea to Summit eVent Compression Dry Sack

user rating: 4.5 of 5 (11 reviews)

A necessary accessory for any down sleeping bag, combining water resistance with good compression. A bit heavyweight, but it’s definitely lighter than a pound of water inside your sleeping bag. Quite durable and very convenient to use.

Reasons to Buy

  • Offers good protection from accidental water exposure
  • Easily compressible
  • Durable 70D Nylon fabric, lasts for years
  • Offered in various sizes

Reasons to Avoid

  • A bit heavyweight
  • Larger sizes are quite expensive

Fully compressed XS bag with 3-season sleeping bag inside (compared to 450ml Toaks mug) Before purchasing a pair of such bags in 2013 I traveled a lot with synthetic sleeping bag packed into a regular fabric compression sack. In bicycle trips sometimes we have to ride under a week-long rains, so a good protection against water exposure (especially in case of sensitive equipment, such as sleeping bag) is a must for us. We know that the water will always find a way under any rain cover. Traditionally we packed our gear to plastic bags from nearby shop (or carried a roll of durable trash bags in long trips), and in really bad weather we doubled the bags for ultimate protection.

Dry Bag

Sea to Summit Lightweight Dry Bag First Aid

user rating: 4.5 of 5 (1 review)

Quick to spot, this easily identifiable dry bag is an ideal way to store one’s First Aid Kit. This waterproof bag is available in 1L and 3L sizes- ideal for the minimalist, groups, or a first responder with a larger First Aid Kit. Being waterproof (not submergible), this bag is ideal for virtually anyone on the go- not just for hikers and water sports.

Reasons to Buy

  • High Visibility (Also Light Reflective)
  • Clear Window To Identify Important Contents
  • Waterproof

Reasons to Avoid

  • Plastic Buckle/D-Ring May Break Over Time

SUP'ing at Saltpeter Creek near the Chesapeake Bay   In the ever-growing field of outdoor recreation, few innovative products catch the eye of the ‘Outdoor Industry’. Born in Australia in 1983, Sea to Summit continues to modernize the outdoor world with the First Aid Lightweight Dry Bag. Although simple, the idea of a high visibility First Aid Kit seems to be a ‘no brainer’…   3L version next to a standard 32oz. Nalgene bottle for reference High visibility is important for locating important items, like a First Aid Kit  This dry bag (First Aid Kit not included) has an easy to use roll-top style closure, with a D-Ring.

Top Pack Pocket

Granite Gear Hiker Wallet

user rating: 5 of 5 (1 review)

This great little product may seem unnecessary, but it will grow on you! I recommend the Hiker Wallet to anyone that goes into the backcountry that doesn't want to carry their big heavy wallet!

Reasons to Buy

  • Inexpensive
  • Weighs next to nothing
  • Convenient
  • Durable

Reasons to Avoid

  • Um... mine didn't come with a cool mini carabiner? Lol
  • Not waterproof

Okay, I admit it—this was an impulse buy! But I am happy that I bought it! This is a great little product from Granite Gear that I have been using for several years now. It's one of those things that isn't really necessary, but you'll be glad you have it. After I purchased it, I thought "Well this is silly. I don't really need this." But over the years, I've realized its worth, and it has become one of those items that goes with me on every backpacking trip. Face it—the wallets we all use everyday are full of stuff that just isn't needed (or wanted) in the backcountry.

Pack Pocket

Granite Gear Add-on Pocket

user rating: 5 of 5 (1 review)

A handy pocket for keeping small items or gear secure and handy. The Granite Gear Add-on Pocket can be installed vertically or horizontally on a shoulder strap, waist belt, MOLLE webbing, compression strap, etc. Foam padding protects what’s inside, and provides some insulation from the cold for battery-powered gear.

Reasons to Buy

  • Universal fit
  • Ease of attachment and removal
  • Shoulder strap attachment is quite sturdy
  • Size

Reasons to Avoid

  • None for me

I bought this add-on pocket just for carrying my cell phone in a safer place than pants or chest pockets. It also keeps it from getting all sweaty. My iPhone 13 Pro fits almost perfectly, and with the opening at the top of the pouch I don’t have to worry about the phone falling out if I forget to zip it up. This was not the case when I carried it in my jacket’s chest pocket, and it resulted in my walking several miles back and forth next to my trail, looking for my phone in a couple feet of snow.

Nite Ize S-Biner

user rating: 4.5 of 5 (3 reviews)

One of the best backpack / keychain accessories available. The flexibility and practical nature of the S-Biner allows for countless applications. Usage ranges from securing keys to a belt loop to hanging a lantern or water bottle from my pack.

Reasons to Buy

  • Small
  • Durable
  • Practical

Reasons to Avoid

  • No locking mechanism
  • Spring clip is a weak point

Usage: The S-Biner is a straightforward piece of gear. The dual hook nature allows a user to latch objects to other objects. The spring clip makes this task super easy, and keeps the attached item secure.  Features:  Due to the simplicity of the S-biner, there isn't much to talk about. The device is composed of two hooks in an "S" shape. A metal wire acts as the clasp, and is mounted in such a way that it springs closed. The clasp is very easy to open and close.  Durability: The S-Biner can take the abuse within reason.

Pack Duffel

Gregory Alpaca Duffle

user rating: 5 of 5 (2 reviews)

This is a review of the largest (120 liter) Alpaca, whose primary role will be long trips and transporting my big backpack and gear. Durable fabrics and features mean the bag will last a very long time. It has comfortable shoulder straps and multiple handles for getting around. Top opening is big, a plus for packing. If there is a downside, the removable shoulder straps lack a quick release—takes some work.

Reasons to Buy

  • Durability
  • Shoulder carry
  • Multiple handles
  • Big opening for packing
  • Storage options, small but useful

Reasons to Avoid

  • Weight
  • Cost
  • Removing shoulder straps

  BASIC INFO Shows how the shoulder straps attach at the top. Dog and starfish not included.   The Alpaca 120 is a big bag, no way around it. Capacity is 120 liters, or about 7,300 cubic inches. It weighs about 4 pounds, empty. [for the sake of comparison, the extra large LL Bean Adventure Duffel that the Alpaca replaced holds 139 liters and weighs a little less than 3 1/2 pounds]. The main pack is made of 900 denier polyester ripstop with a TPU coating on the outside, making it effectively waterproof in the rain unless there is a concentrated stream of water hitting the zipper and avoiding the overlapping cover—very unlikely.

Top Stuff Sack

Granite Gear Air Zippditty

user rating: 5 of 5 (2 reviews)

Just the right size (.6L) for the little odds and ends you want to keep in one place when hiking, camping, backpacking, or any other outdoor activity. Well-made bags in high visibility colors, great for small first aid kits, fire starting kits, snacks, electronics, and more. A perfect way to bring some order to your backcountry existence.

Reasons to Buy

  • Good design, good materials, and lifetime guarantee
  • Translucent fabric allows one to see contents
  • Strong zipper provides bag with structure (it arches)
  • Weather-resistant (silnylon fabric + weather-resistant zipper)
  • Bonus bag! (reusable packaging)

Reasons to Avoid

  • Weight could be lighter (but fine for most users)

Multi-use Organization for the Outdoor Enthusiast As any outdoor enthusiast knows, organization can save time, prevent loss, and bring peace of mind to one's outdoor experiences. Pieces of kit lost in the depths of a pack or scattered in the pack's "brain" only bring frustration. Where is the other battery? Where did my pocket knife go? Didn't I have another Clif bar? These are questions I've asked myself many a time. Despite knowing the value of organization, I have at times hesitated to purchase gear for organization, relying instead on plastic bags or skipping it altogether in the name of saving weight or spending my money on other, more essential items.
