Solitary 35 Ultralight

We have combined our knowledge and experience with the latest technology in ultralight materials to make what we believe is the best 35L ultralight mountaineering/climbing pack in the world. Named after one of the most iconic features in the Blue Mountains, the Solitary 35 combines the trifecta of ultralight, durability and comfort. We have not sacrificed any of these to deliver you the ultimate pack. 

We have carefully selected materials that have the best environmental credentials in their field - including fabrics made at Bluesign® approved facilities from recycled pre-consumer waste and recycled plastic bottles. The pack itself has been designed and made in Katoomba - Australia, by professional machinists who take immense pride in their craftmanship, are paid a real living wage at a facility that is powered by 52 solar panels and acheived a Gold rating from Low Carbon Living - Blue Mountains

We have tested this pack in the fierce Australian bush, the alpine peaks of Europe and the vast Red Rock of Nevada. Designed by a team of people at Summit Gear that have decades of experience is climbing, mountaineering and hiking, we know you will love this pack as much as we do.

The body of the pack is made from UHMWPE - Ultra 200 X which has a tensile strength that is 15x stronger than steel. It is incredibly lightweight, abrasion resistant, waterproof, UV resistant and is incredibly hard to tear. Weighing in at 119gsm this is the ideal material for the highest performing pack.

The back of the pack is made from Ultragrid™ – a true innovation in sustainability and strength. Ultragrid is woven at a Bluesign® approved facility with 210d recycled yarn from pre-consumer industrial waste and is interwoven with Dyneema thread.  Ultragrid™ provides exceptional tear-strength and visual impact.  UltraGrid™ has a C0 DWR coating, free from toxic PFCs, and is finished with a waterproof 1500mm PU backing.

We have incorporated a stretch pocket into the hip belt – ideal for a smartphone and snacks which is made from UltraStretch™ - a 4-way stretch mesh woven with the highest quality Ultra fibers. This fabric is so tough that our auto-cutting machine cannot cut it, thus requiring hand cutting with carbon shears to bring you the performance and longevity that would expect in any Summit Gear pack.

The base of any pack takes a pounding, we have used Ultra 400 X UHMWPE (non branded Dyneema) which is highly abrasion resistant yet incredibly lightweight.

The Solitary 35 seams are fully taped sealed to ensure that the pack is entirely weatherproof. The fabrics used on the pack are waterproof and the taping of the seams significantly reduces the amount of water that can get through the pack, making it suitable for use in wet climates. 

The Solitary 35 has a removable frame sheet. The frame sheet provides extra support during those long days moving through the mountains. However if weight is a premium it can be easily removed, leaving a very comfortable cored 10mm closed cell foam pad, and at 650grams is ideal for climbing epic routes.

There are virtually no commercial manufactures of hiking packs left in Australia – we aim to kick this trend and prove all the others wrong! We can do this by cutting out all the middle guys, enabling local manufacturing to support living wages and delivering exceptional value and innovation directly to you.
