Tall tent pole from two trek poles and 3 straps


Three straps are included with the pyramid tarps. With these you can make a long pole for setting up a pyramid tarp using two trekking or ski poles. Using adjustable trekking poles makes the tarp pole adjustable too.

Thoughts on Tarp Setups


Some of nylon’s stretch can be mitigated by how the fabric pieces are cut out. Curves etc. in seams and hems can help maintain shape. I far as I know, nylon is still the fabric of choice for shock absorption (parachutes, ropes) and does a good job for shelters suddenly loaded by wind or snow.

It does sag a bit at times from temperature drops or moisture. In something like a pyramid tarp, having a method for adjusting the pole upward to take up slack from within the shelter is nice. If your tarp pole is not adjustable, this could be as simple as having a stone handy to place underneath the pole. If you use outside shear poles, reaching under the hem and pulling the two pole bottoms inward can do the same.

Two wooden poles can be  lasted to hold the tarp up from outside.

Be sure in any case or fabric type you stake out the hem in the right shape. On a symmetrical 4 sided mid, a diamond shape instead of a perfect square will produce saggy walls with any fabric. Floored shelters are easier to get the stake out pattern correct. On a floorless shelter you could tie tiny cords corner to corner to insure proper and repeatable layouts.

Stake corners in a perfect square and slightly stretched. This prevents a diamond staking pattern which will cause one corner to be up in the air.

Take a pyramid tarp, cut it in half and add an A Frame door and you have the Alphamid TM. Half Pyramid floorless shelter 4×8 by 5′ feet tall. 30d silnylon Weighs 13.5 oz A floorless tarp which is quick to set up, light and inexpensive. A favorite for winter campers, it can be set up over a snow pit for extra roominess. It includes a stuff sack. Use your ski probe poles, hang it from a tree limb or order the separate shock corded pole to set it up. Just clip the buckle at the bottom of the door, zip up the zipper, stake out the four corners evenly and put up the pole. Additional tie outs are on the center seams. The apex is reinforced , the zipper is a #5 coil. The taller steeper pitch sheds snow and rain much better than the competitors shelters as well a providing more headroom. Includes 1 oz. pole connector (3 webbing straps) so you can use two trekking or ski poles to make a height adjustable pole. Fabric is not flame retardant and will burn and melt when in contact with high heat or flame. Keep away from camp stoves, gas lanterns, campfires etc.
Great shelter for Search and Rescue-very light and you can set it up over a prone victom without
moving them. Current color is grey.
