Backpacking Background: I've spent a significant amount of time outdoors working as a research geologist in the field under a variety of weather conditions and environments. I've traversed mountains, swamps, tropical island interiors and coastlines and even crawled around inside caves. I'm also an avid traveler and amateur adventurer- I've driven 1720 mi (2770 km) across Peru on a 3-wheeled motorcycle taxi and will soon embark on a lengthy 40-day car camping trip from England to Mongolia. I might not always be backpacking, but give me a piece of equipment and I guarantee I will put it through its paces!

The 115L SealLine Boundary Pack comes with all straps and buckles attached to the bag in their proper configuration. Included are the shoulder straps with an adjoining chest strap, a waist strap, top-to-front cargo straps and corresponding snap buckles, and a brief instruction manual with a diagram detailing strap placement and product care.
The SealLine Boundary functions as a backpack-portable, waterproof and watertight dry storage bag. Sealing the bag is accomplished by pinching the top of the bag together, forcing out any excess air, rolling the top of the bag downwards at least once, and then buckling the ends securely to the sides. The more wraps achieved while rolling the bag closed, the better the seal. When rolled-up properly and cinched down tightly the bag is water-tight, and the reinforced rubberized skin is impervious to water or moisture getting into or out of the bag.
Field Information: I've used SealLine's Boundary Pack under extended and particularly demanding conditions on two occasions, the first being on a ten-day field research expedition to Sapelo Island, Georgia, and the second on a month-long trip across Peru. Those locations and subsequent product performance are as follows.
-Sapelo Island lies on the Georgia Atlantic coastline of the U.S., with an interior covered by pine forest and surrounded on three sides by tidal creeks and coastal marsh. Weather conditions for September 2011 were hot and humid at 80 to 95 F (27 to 35 C), interrupted by occasional thunderstorms and heavy rains for periods of 2-4 hours. Terrain consisted of marshlands and tidal sand bars, with transport to and from location by boat. Hikes were typically one to two hours through wet and muddy conditions, with some waist-deep wading. Tides were semi-diurnal (two high and two low tides over a 24 hour period) with a range of approximately 8 ft (2.5 meters) above sea level.
-Performance at Sapelo Island, GA: each morning and evening, for ten days, the bag accompanied me on lengthy boat cruises and performed beautifully. Its rugged design withstood constant battering and abrasion aboard a cramped watercraft with all sorts of loose equipment rolling around. When closed securely it kept contents dry and protected from the elements, which ranged from sea spray to thunderstorms and torrential downpours. Though the bag frequently marinated in bilgewater for hours at a time, lying in the bottom of the boat until something inside it was needed, I never experienced any problems with the contents getting wet. Hikes using the bag as a pack were relatively short, typically less than a half mile at a time through marshland, but its rubberized shell, shoulder straps and chest buckle were an absolute necessity given the conditions and unstable terrain. When loaded with heavier items it would become uncomfortable over long distances and/or for extended periods of use, but the straps were adequate for loads under 25 lb (11 kg).
-Peru exhibits nearly every type of climate and terrain imaginable, and I can safely say I experienced all of them while traveling from Piura, on the northern coastline, to Urubamba in the southern mountains in late September of 2012. Weather conditions ranged from hot and dry, hot and humid to cold and wet, and included rain, snow and even hail. Temperatures ranged from 25 to 90 F (-4 to 32 C) and elevations from 100 to 14,000 ft (30 to 4270 meters). Terrain crossed consisted of desert, arid coastal lowlands, lowland jungle, wet highlands, dry highlands, and alpine. For this trip the bag was used almost exclusively as luggage, secured to the back of an open 3-wheeled motorcycle taxi on a 1720 mi (2768 km) 14-day road trip. When not traveling on the road the bag was used as a backpack for short periods over the course of two weeks.
-Performance in Peru: for the first week the bag stayed on my back as I jumped from hostel to hostel in Lima. Weighing in at 32 lb (14.5 kg) given the contents, the bag was manageable for an hour or so at a time, but occasional breaks were necessary to relieve discomfort. The bag's simple, sleek and rugged design proved advantageous for repeated taxicab rides and use as a checked bag on airline flights. Nothing ever spilled out and when I had packed conscientiously I could easily retrieve items from the top when needed. Following a flight to the city of Piura, the bag was strapped to the back of a motorcycle taxi and became a piece of weather-proof luggage for a two-week journey across the country. It was removed every night and replaced each morning, sometimes carried out on short excursions, but generally remained on the back of the mototaxi for at least 12 hours each day. By the end of the trip the bag was filthy, reeked of gasoline that had leaked from a spare can, was thoroughly scratched and scraped and had one small puncture, but none of its contents was ever exposed to the weather, mud, road dust or the gasoline, at any point during the trip. It again reverted to use as a large pack for another week before making a return trip to the U.S. as checked luggage.
The SealLine Boundary Pack is a rugged, durable, reliable and convenient top-loading weatherproof and waterproof backpack for short-range backpacking and/or outdoor activity under the most extreme environmental conditions. Its especially well suited to extended outdoor exposure in wet, sandy and/or muddy conditions, motorcycle and boat travel (kayaking, canoeing, etc). Available in a variety of colors and sizes, there are plenty of options for both style preference and cargo capacity.
Things I like:
1. Extremely durable, rugged, waterproof and water-tight rubberized design.
Roll-up top makes storage capacity more flexible as items are added/removed.
3. Easy to pack and unpack.
4. Low-maintenance, easy clean up and repair if punctured.
5. Backpack straps are a big plus when compared to duffels and dry sacks.
Things I dislike:
Shoulder straps, chest strap and waist belt are inadequate for extended use or excessive weight.
2. Dry weight of 3 lb 6 oz (1530g) means it's a bit on the heavy side.
3. I worry that the buckles may be susceptible to cracking or breaking.
