The Isotherm Jacket is a lightweight synthetic jacket that is super warm and extremely breathable. Ideal for active use in cold conditions.

Description  Features

Whether backcountry skiing or ice climbing, the Isotherm Jacket is built for the active purists.

The lightweight 20-denier Pertex Quantum down-proof fabric is filled with Polartec Alpha insulation for warmth when you’re on the move; breathable Polartec Power Stretch panels allow uninhibited movement. Layer this incredibly lightweight puffy over a midlayer for warmth when you’re on the move.

 
  • 20 Denier Pertex Quantum Fabric
  • Polartec Alpha Insulation
  • Polartec Power Stretch® Panels
  • Zip Hand Pockets
  • Zip Chest Pocket
  • AirExchange Lining
  • Interior Mesh Pocket
  • Elastic Bound Cuffs
  • Elastic Drawcord Hem
  • Angel-Wing Movement
  • US style Zipper with slider on the opposite side to UK Zipper

The Polartec Power Stretch side panels gives the shoulders and sleeves excellent breathability and a four-way stretch for uninhibited movement, but the real story is in Polartec Alpha itself, designed to be worn when you are active - so on the move - there are alternative insulation garments that are more suited to wearing around camp - Strata is about keeping you vented even though you are also being kept insulated.

Its quite a breakthrough, especially for cold weather walking when you need insulation but start sweating hard when you reach a strenuous bit. Weight for weight Polartec Alpha is only about half as warm as Primaloft so the king of insulation keeps its crown - but Alpha has its place - I recently wore an Alpha garment all day while walking in Corsica in particularly cold conditions and stayed warm & comfortable for the duration - I kept checking my baselayer, which stayed completely dry.

The Jacket features an AirExchange Lining that will help the jacket to breathe and has a bonus of feeling soft against your skin. There are 2 good sized hand warmer pockets with a a small chest pocket for storing a phone or other valuables. There is also a large interior mesh pocket that would be good for storing gloves or a hat. The elastic bound cuffs and elastic drawcord hem will help prevent cold air from getting in. The Isotherm Jacket is ideal for keeping warm during active use with out over heating.

UK Orders

We aim to ship all orders placed before 3pm Monday to Friday, on the same day. Free shipping is offered for UK Orders over £15 order value. The form of shipping will be at our discretion and will be at the most cost effective service. For most parcels this will be Royal Mail Second Class Post, the timescale for delivery is not guaranteed but Royal Mail aim to deliver second class post in 3-4 working days. Some parcels may require a signature.

Faster Tracked Services

Faster shipping options can be purchased at the checkout - see the drop down menu, First Class post is available, as is Next Working Day Delivery. We can arrange Next Day Delivery for a Saturday (when the order is placed on Friday) - call us for charges on an individual basis (01740 661467).

EU Orders

We aim to ship all orders placed before 3pm the same day. The default shipping is 'Standard Delivery'. This is an airmail service which does not offer tracking but is very reliable. We have learned from experience that transit times for non-UK orders can be very unpredictable. To geographically close countries in Europe the times are generally up to 4-5 days but can sometimes take a lot longer - we don't know why.

So, for EU Orders over £15 in value we offer FREE delivery, but the service time is unpredictable. If you need your order by a specific date you can opt for a faster service at the checkout.

Faster Tracked Services

Faster tracked shipping options can be purchased at the checkout - see the drop down menu on the checkout page for options. Typically the service we can offer is 2,3 or 4 working days, if you require a faster delivery than is showing on the drop down menu please contact us at info@worldbackpacker.co.uk as we may be able to help.

Rest of World Orders

We aim to ship all orders placed before 3pm the same day. The default shipping charge is 'Standard Delivery'. This is an airmail service which does not offer tracking but is very reliable. We have learned from experience that transit times for non-UK orders can be very unpredictable. To geographically close countries in the times are generally up to 4-5 days but can take a lot longer - we don't know why. Countries farther afield generally take longer but the spread of transit times is amazing, we have been notified of parcels arriving in Australia after 3 days and others taking a month and (rarely) longer than this.

So, while the shipping options for ROW are quite cheap the service time is unpredictable.
