Hydraulic Dry Bag

ENGINEERED FOR STRENGTH AND DURABILITY

$64.95 – $99.95

Sleeping Bag Temperature Ratings Explained

The EN Rating scale is a scientific test to determine the warmth of a sleeping bag. The test produces a Lower rating (for male sleepers) and a Comfort rating (for female sleepers). Both are listed in the features table on the product page.

A unisex sleeping bag with a Lower limit of 23ºF means a man should be comfortable down to air temperatures of 23ºF. The same bag will also have a Comfort limit, in the realm of 32°F, so a woman would be comfortable down to an air temperature of 32ºF. These ratings require a sleeping mat with an R-Value appropriate for expected ground temperatures – without this, the sleeping bag itself is unlikely to keep the sleeper warm enough.

A variety of factors impact sleeping bag warmth - the above temperatures are merely guidelines, not guarantees. It’s important to think of a sleeping bag, an appropriately insulating sleeping pad and a liner as a sleep system. For example - if you plan on sleeping in nighttime air temperatures of 27ºF / -3°C, choose a bag with a gender-appropriate rating of 23°F / -5°C, plus a sleeping mat with an R-Value of 2.5 to 3, and consider a Reactor thermal liner.

Description

The Hydraulic™ Dry Bag is the burliest dry bag we make. It is designed for demanding conditions where rough and tough treatment is to be expected. The 600D heavy duty abrasion resistant TPU laminated fabric and RF welded construction throughout give the Hydraulic its superior strength. The interlocking non-wicking roll-top makes it easier to close the large format closure, and RF welded lash loops provide secure attachment points. An oval base means the dry bag won’t roll away when you set it down. All models use our Field Repair Buckles, which can be replaced in seconds using a Philips screwdriver.

ARE HYDRAULIC DRY BAGS...?

  • Suitable for paddle sports? Absolutely. The tough TPU laminate is perfectly suited to watersports use, even in environments where sharp/abrasive surfaces may be present.

  • Waterproof? The fabric is more than adequately waterproof (10,000 mm hydrostatic head) – just avoid submersion, as water can seep through the roll-top closure of any dry bag.

  • Suitable for canyoneering? Yes and no. Canyoneering is extremely hard on equipment – a Hydraulic Dry Bag is unlikely to survive more than a couple of seasons without needing to be retired.

Technical Features

600D Hydraulic Fabric

The burliest fabric in all of Sea to Summit's products, this is constructed similarly to our Stopper fabric but has a few key differences. The Hydraulic fabric starts with a 600 Denier carrier fabric, then has TPU laminated to both sides of it to create an unstoppable waterproof, abrasion, and puncture resistant fabric. With two full and separate layers of TPU, you have some built-in redundancy against holes from abrasion. This fabric is also UV stabilized and won't crack in the cold.

Thermoplastic Urethane (TPU)

Thermoplastic Urethane (TPU) is a PVC-free material used in a number of functional areas within Sea to Summit products:

 

  1. As an airproof barrier in our Air-Sprung Cell™ and Self-Inflating mats. Here it is used in a liquid-extruded format – the TPU bonds to the face fabric for the highest possible level of reliability.
  2. As a waterproof barrier in our Accessory Guide Cases and Map Cases; and in several models of our Dry Sacks. Here it is used in a film format, where its superior flexibility (even in cold weather) and waterproofness are key.
  3. As a waterproof barrier in the Nylon Folding Bucket. This particular film is also food grade – ideal for water storage.
  4. As a transparent window in View Dry Sacks and Travelling Light products – allowing you (and TSA inspectors) to see the contents.

PVC Free

This product is free of any Polyvinyl Chloride (PVC). This means that the production process is significantly more environmentally friendly, and the disposal of the product at the end of its life will also not burden the environment. With advances in modern polymers, it also means there's no reduction in performance.
