Sea to Summit Trek TKI is a great all round sleeping bag, insulated with water-resistant down for warmth and compressibility, ideal for colder temps with ratings 5°C to 0°C comfort limit. The sleeping bag is semi-rectangular in shape wider than a mummy bag for some extra room to move from hips through to feet. Has full length zip so can be used as a quilt. Measures 183cm long with width 81cm at shoulder / 54cm at foot.

Ideal for hiking and camping with bag weighing 830g. Compresses down to 5.1L and comes with its own compression bag. 


  • Insulated with high-loft 650-fill-power Ultra-Dry duck down for warmth, light weight and compressibility; EN Lower Limit rated to 0°C
  • Ultra-Dry Down is a water-repellent polymer treatment applied to the 650-fill down; retains 60% more loft and absorbs 30% less moisture than untreated down
  • Baffle construction allows the down to remain fully lofted and keeps it from shifting
  • 30-denier shell fabric treated with a durable water repellent (DWR) finish and a 20-denier soft-touch, breathable lining
  • Full-length side zipper and foot zipper allow bag to be converted from sleeping bag to a duvet/down comforter; this also allows 2 Sea to Summit bags to be zipped together
  • Oversize draft tube backing the 2-way zipper keeps the warmth in and the cold out; zipper is backed by stiff, anti-snag tape for smooth operation
  • Stitched hood panels provide structural support to enclose your head in colder weather, and a static draft tube runs around the hood to maximize warmth around your face
  • Differentially cut inner layer is smaller than the outer layer to create a consistent thickness of insulation that prevents cold spots
  • Large zippered interior security pocket is great for stowing a few essentials, alleviating middle-of-the-night fumbling and preserving battery performance in cold weather
  • Comes with an Ultra-Sil compression sack


  • Temp ratings: 5°C comfort, 0°C lower limit, -15°C extreme

Which courier service do we use? We typically use Castle Parcels and Post Haste couriers. Delivery is signature required (except for rural deliveries) … feel free to send us delivery instructions if you’d prefer courier to leave your item (no signature required). Sorry, the couriers cannot make PO Box deliveries. 

Are tracking details provided? Once your purchase is dispatched an automated email will be sent to you with the courier tracking details for you to follow your item's progress. 

Can shipping be combined? Purchases can be combined to save on shipping costs but the final cost will depend on total weight, volume and destination. If unsure or you have a question, please contact us and we can let you know what combined cost will be. Maximum weight is limited to 25kg to send in one package.

How long does shipping take? We try to get your order on its way as soon as possible. Generally, when orders and payments are confirmed in the morning we do our best to ship them out on the same day. Orders confirmed in the afternoon will be dispatched the following day. For orders placed on Friday afternoons or over the weekend, they will be sent out on Monday.

Typical delivery times are next working day for Auckland and North Island addresses and 2 working days for South Island delivery. Add an extra day for rural (RD) addresses. Note that during the December peak season courier company delivery may experience some delays due to greater volumes.

If for any reason you have not received your order in the expected timeframe, please refer to the emailed tracking link and contact the courier company with your tracking number. As the courier service is ‘signature required’, if you are not home to receive your order when it is delivered, a calling card is left for you to arrange a convenient time for redelivery.



Which service do we use? We use eParcels - items are picked up by NZ Post and sent to Australia where they are delivered by Australia Post. When dispatched you will receive an automated email with the tracking details. Delivery is signature required. Faster courier services are also available with FedEx but please note that rates are for major cities only. For rural areas please contact us to confirm pricing as this can vary greatly.

How about courier services? We can also send items via FedEx which is quicker, tracked and signature required. This service is more expensive - please contact us if interested and we can quote you the actual price depending on product you're interested in and delivery destination.

What about taxes? Please note that any taxes or customs duties due for purchases entering your home country are not included in the purchase price and must be paid for by the recipient.    



We believe our reputation and future is only as good as our product and the satisfaction of our customers. We strive to provide quality products, however, if there is any quality issue, we will do our best to rectify the situation as quickly as possible. Purchases should be checked upon receipt and any problems reported to us within 10 days, identifying the problem (preferably with photo evidence).

All purchases are covered by a 12 month warranty and the Consumer Guarantees Act against defects in manufacturing or materials. As is common practice with most camping goods retailers in NZ there is no warranty for storm or wind damage, normal wear and tear, UV degradation, accident or misuse.

After consultation with us, the buyer is responsible for costs of returning any item if necessary (as many issues can be resolved online) for assessment to determine repair, replacement or refund as appropriate. We will try to repair or replace any faulty parts or item to factory standard. If this is not possible we will exchange it for any of our other products to equal value, or where none of these is possible we will refund the cost price (delivery charges are non-refundable).

Where products have been used, packaging has been opened the buyer or the buyer has had a ‘change of mind’, they cannot be returned for refund.
