Background: As an avid hiker all of my adult life I have thru-hiked the Appalachian Trail in the eastern US and sections of the Pacific Crest Trail in the western US. I currently reside in the desert southwest and spend most weekends and all vacations hiking and exploring. I prefer long hikes and traveling with a light pack. My current base backpacking weight (not including food or water) measures about 10 lbs (4.5 kg). My web site: http://www.toddshikingguide.com/
contains information, descriptions and photographs of many hikes and canyons in Arizona and Utah.

Field and Test Information:
 

Location(s) of test:

The bug liner was taken on several trips to various locations around Arizona in the Kaibab and Coconino National Forests.

Terrain:

Terrain consisted of juniper and pine forests at higher elevations to desert grasslands. Elevations ranged from 4000 to 7000 feet (1200 to 2100 meters).

Weather Conditions:

Night time temperatures ranged from lows in the 40's F (9 C) to the 70's F (21 C). Nights were clear with occasional wind.

 

Description of Experience and Comments on Product Performance:
 
The Integral Design Silshelter Bug Liner is a fully enclosed non-free standing shelter with a no-see-um netting body and nylon bathtub floor. The bug liner may be used as a bug proof shelter on dry nights or in conjunction with the ID Silshelter if inclement weather threatens.

Setting up the Bug Liner:
The Integral Design Silshelter Bug Liner requires 6 stakes to set up, one for each of the four corners and one for the front and back. Since no instructions came for setting up the liner, my technique has been to stake out each of the corners. Each corner has a loop of webbing connected to it for this purpose. Next I place a hiking pole (point down) at the head of the tent placing the handle of the pole in a cup shaped piece of fabric designed for that purpose. I then stake out a guy line located at the top of the liner to hold the hiking pole in place. My experience is that the cup shaped pole holder is a little too small for the hiking pole I typically carry (a Black Diamond FlickLock). The top of the handle of this pole has a broad flat area to distribute the pressure across the hikers hand. This works nicely when hiking with the pole, but does not fit very well into the holder provided on the liner.

Setting up the foot of the liner is a bit of a mystery to me. The foot has three loops sewn at evenly spaced intervals around the foot box with a single cord routed through the two outer loops. My technique to date has been to wrap the cord around a stick at the level of the foot box, about 24 inches (61 centimeters) above the ground, then stake the cord into the ground to secure it. While this set up technique is functional, it doesn’t seem correct. Because only the outer two loops are used at the foot box, the tension of the cord pulls the loops together, creating a crease in the liner's bug netting. I would think that, if properly set up, all fabric of the liner would be taut. I have not figured out a successful means of setting up the liner to achieve this result.

The entire process for setting up the Bug Liner takes me less than 2 minutes. Since just the head and foot of the liner require guy lines, there are only two trip hazards associated with the shelter.

Once the liner is set up, if you have the Integral Designs Silshelter, you simply throw this over the top of the Bugliner and use the same stakes to secure it in place. An additional stake or two is required to secure the door of the Silshelter in case of rain.

Description of Product Performance:
The first thing to mention with the bug liner is that it is completely enclosed. With the door zipped up the occupant has a barrier of mosquito netting or nylon between themselves and any biting bugs. As a shelter that advertises protection from bugs, the product does what it is intended. With that settled, let’s take a look at some of the other features.

After setting up the liner it’s time to crawl inside. One thing I found is that the pole that supports the head of the liner is propped up right in front of the ‘C’ shaped zipper door. This reduces the amount of room you have available to get inside the liner and makes it impossible to enter from the left side facing the shelter (since the ‘C’ shaped door doesn’t open as far on this side). I did not find this to be a problem when using the liner as a solo shelter, but with another person inside the shelter (particularly if they are occupying the right hand spot) I had to carefully crawl over them to get inside. This is complicated further by the fact that the door has a 3.5 inch (8.9 centimeter) lip above the ground that must be stepped over when entering or exiting.

Once inside, I found that there is enough headroom to sit up if the liner is used as a solo shelter so that I can sit right in the middle with my head at the tallest part of the shelter. Because the liner is shaped like a triangle, the slope of the netting drops quickly from the center of the liner. It is therefore not possible to sit up when there are two people in the liner since there isn’t room to sit in the middle and the roof is not tall enough on the sides where the two people would be sitting. There is enough room for two people inside the shelter to sleep comfortably though it’s a snug fit. There is little extra room available for any gear or personal items though. For a solo camper, all equipment could be brought inside the shelter at night if desired. For a couple, most of the gear would have to be left outside.

One thing that did bother me slightly was the fact that the sides of the liner sagged in towards the center. This is due to the ‘A’ frame design of the shelter and the fact that it is secured at the corners, head and foot only (there are no guy lines for the sides of the liner to pull them out. Because the sides bow inwards, it reduces the amount of space available in an already confined space.

As a standalone shelter (in pleasant weather), the bug liner is very breathable due to the fact that the entire body is made from no-see-um netting. Breathability is hampered somewhat when used in conjunction with the Silshelter since it simply drapes over the top of the bug liner with no tie out points to provide an airspace between the two shelters. I found that by keeping the door of the Silshelter wide open at night, the movement of air was sufficient to keep condensation from building up within the shelter (keep in mind that this test was conducted in Arizona where humidity is fairly low). I have not had the opportunity to test the shelter during a rain storm with the Silshelter battened down against the elements.

 
Conclusions:
 
My experience with the Integral Design Silshelter Bug Liner has been somewhat mixed to date. The lack of pitching instructions and my inability to get the foot of the shelter set up tautly leads me to question whether I'm setting it up properly. The shelter works very well for the purpose it's intended (keeping the bugs at bay), but is somewhat confining when used as a shelter for two.

Likes:

  • Light weight
  • Packs fairly small
  • Sets up quickly
  • Doesn’t have a lot of guy lines to trip over
  • Completely enclosed, keeps the bugs out
  • Very breathable when used as a stand alone shelter
Areas for Improvement:
  • No set up instructions, particularly for the foot
  • A little small for my tastes with two people inside
  • Not possible to sit up when two people are in the shelter
  • Sides of the shelter bow inwards
  • Between the location of the hiking pole and the lip, the door is a little difficult to get in and out of
  • Fabric hiking pole cup is too small for the handle of my hiking stick
Long Term Test Plan:
Over the next 4 months, I plan to conduct additional tests on the  Integral Design Silshelter Bug Liner. I have several hiking trips planned in Arizona and Utah and plan to use the Bug Liner exclusively during this time. I am hoping to further test: comfort in the heat of the AZ summer, rain and wind resistance during the summer monsoons and longer term durability.
